<Michael_> Hi everyone!
<lundman> hno: good luck with uboot, its hard work, but worth it in the end :)
<Michael_> Is there anyone that can help with a bad focaltech touchscreen after wrong firmware flash?
<Michael_> I already have tried to flash the eeprom from the touchscreen, but it fails on reading the ID :(
<Michael_> I think the eeprom is empty...
<Michael_> Anyone? :(
<bsdfox> what's stored in the eeprom?
<bsdfox> probably just calibration data and maybe serial number or something
<Michael_> i think it is now empty
<Michael_> the driver does not load because he does not find it...

<Michael_> from what i know, the focaltech touchscreens have a little firmware...
<hno> slapin, odd.. Let me hunt a bit.
<Michael_> did anyone here knows how the FT5406 from focaltech that are found in many A10 tablets works?
<hno> slapin, found it.
<slapin> ah, cool
<Michael_> here is the dmesg that i've got when it tries to update the focaltech eeprom: http://pastie.org/private/15yzlrnf8sqry0nmkiqga
<hno> had a little filter in evolution that kindly hid most new mails.

<libv> jquip: so you got a ttl uart to usb device?
ibrah has joined #arm-netbook
<libv> jquip: you can ignore +?V
<libv> jquip: gnd is any ground you can find
<libv> tx/rx, could be anything
<jquip> libv: yes finally!
<jquip> hno said no way further if i dont get one..
<jquip> so yeah :)
<jquip> but..libv i can't find the darn pins.. where do I connect them?
<libv> jquip: i suggest taking better pictures of both sides of the board, this one is a bit out of focus near the cpu
<libv> jquip: this is the million dollar question
<jquip> libv: hahaha.. yeahh
<jquip> lemme get a better shot and upload... 5 mins..
<libv> if nothing obvious points to uart, like a group of 4 pins made to be soldered, then it usually is on the test pads
<libv> you see a group of 4 test pads to the left of the A10
<jquip> well for what its worth: yes... I have a hunch it could be those... to the top left where the board ends right?
<jquip> center top side..
<jquip> its already kinda marked with a white border...
<libv> i count 5 connections there
<jquip> yes there are 5 and one of them (at the bottom) is square..
<jquip> if you notice it a bit..
<libv> square is gnd.
<libv> notice that i stated 3-4 for uart.
<libv> the one you are talking about is probably usb
<jquip> hmmm, it seemed like the only obvious one though..
<libv> count.
<jquip> ahah yes I counted there are 5 :D
<libv> so definitely not
<jquip> uploading front and back pics in 10 mins..
<hno> jquip, hard to say with such blurred picture. But there probably is uart somewhere as they have provided pads next to the CPU for JTAG but not UART.

<hno> jquip, odd. Looks like serial may be going to that P5 after, on pin 1 & 2. The square pin is NOT GND.
<hno> (pint 1)
<hno> s/pint/pin/
<ibot> hno meant: (pin 1)
<hno> jquip, what is connected on P4? Some USB device?
<jquip> well this guy has three usb ports,, one of which is OTG..
<libv> :)
<jquip> it apparently had a another mini usb port(dev port i think) which has been removed.. if you look at the left of the three usb's
<jquip> you can see the dent
<jquip> ahemm... I
<jquip> i'm still not as brilliant as you guys..
<hno> jquip, what do the cables connected in P4 connect to?
ibrah has quit [Ping timeout: 252 seconds]
<jquip> P4 definitely seems to be that dev mini usb
<jquip> which was removed
<hno> P4 is straigt opposite on the board, next to the GL850G USB hub.
<jquip> Oh!! that one
<jquip> *slaps head... i didnt see that..
<jquip> that one is going to the webcam
<hno> jquip, I think that board can come with either 3 full size USB, or 2 full size USB and one micro-USB.
<hno> jquip, is that an USB web cam?
<hno> No wifi?
<jquip> arrgh...
<jquip> correction.. p6 -> webcam
<jquip> p4 wifi chip..
<jquip> p6 is toward the right of the p4 header
<hno> Anyway, UART is almost certain on P5 pin 1 & 2 (square pin and next pin).
lerc_ has quit [Ping timeout: 250 seconds]
<hno> P5 and P6 are probably USB ports. Should be easy to verify by starting the tablet and looking what's on the USB bus.
<hno> Err, P4 & P6.
<jquip> mostly seems like.. I'll check what lsusb gives
<hno> P4 looks like it has alternative mounting with on-board wifi USB module on J4.
<hno> In P5 the pins are probably TX, RX, VCC, GND, GND.
<jquip> okay...
<jquip> I've seen other chips which are not part of the main board, with the wifi chip stuck onto it..
sspiff has joined #arm-netbook
<jquip> should i solder the pins onto them now? and fire up minicom 115200
<hno> libv, "Processor Manufacture: AMD " "Processor Model: Allwinner A10 "?
<libv> someone else said in here that the top description should always be ignored
<hno> looks like
<hno> Android 4, but no touch screen.
<oliv3r> Backreading (sorry i'm slow; ps nice sharp pics) it looks like the mini USB is directly connected to the USB port next to it
<hno> yes.
<oliv3r> jquip: you can solder your ground to somewhere that's 'guaranteed ground' (e.g. measure between one of those P5 pins and any gnd/shell and use that) and then just hold your wire against one oft hose wires to 'test' it
<oliv3r> but hno seems to be spot on with square (pin 1) and pin 2 being tx/rx (or rx/tx) so should be fairly easy to figure out which one it is
<oliv3r> test pins for the PS2 port seem to be somewhat exposed at the bottom next to the SD card slot
<oliv3r> and you can solder some extra nand into U9 :D
<hno> So the flat cable in J10 is most likely keyboard. jquip?
<hno> those test pads corresponds to the pins of J10.
<oliv3r> J9 is probably then a PS2 mouse or touchpad?
<oliv3r> though J9 seems to be called GND_K1, could be keypad1 even
<oliv3r> if there's extra buttons maybe?
<hno> The Holtec chip is an EC.
<oliv3r> where did you spot that?
<hno> next to the USB ports.
<oliv3r> ah yes I see
<oliv3r> temperature sensors? PWM for fans etc?
<hno> And USB hub is opposite the board.
<hno> I would guess keyboard + keypad + power button + something more.
<hno> because if they knew how to use the A10 they would not have an EC.
<oliv3r> lol
<oliv3r> so badly designed board?
<hno> Not badly designed. Designed using stuff they know works.
<hno> but very odd layout.
<libv> will the ec get in the way?
<hno> in the way of what?
<libv> like the ec's on x86 which make coreboot/flashrom pretty impossible
popolon has joined #arm-netbook
<hno> not really. It's messy on the X86 laptops as the EC is usually using the same flash memory. In this case the EC has it's own built in mask rom.
<oliv3r> on that holtec chip, port A could be connected to some IC which is also unpopulated. Wonder what they'd want there
<hno> The EC is just there so they did not need to worry about how the PS2 & deep standby modes of the A10 works.
<libv> as for the 13.3" a10 device without a touchscreen: android is not the goal for most of us here anyway :)
<oliv3r> Why are there 2 crystals near the A10? X2 is probably a 32 kHz crystal for the RTC, but X3 ... also can't find the 24 MHz Main osc., don't think it's X4 ..
<libv> but we are a bit of a niche
<oliv3r> which netbook does this mainboard come out of?
<jquip> Hallo sorry was away... hno: J10 is for the keyboard
tzafrir_laptop has joined #arm-netbook
<jquip> j9 is for the keypad
<oliv3r> hah!
<oliv3r> what notebook is this? some more pics to look at? just curious is all
<libv> oliv3r: i think it is the allwinner netbook as pasted all over aliexpress
<libv> the one that resembles the via wm* devices
<libv> board made to fit the same hw it seems, which explains why hdmi is missing
<mnemoc> the only "better" thing yones' laptop has is the screen
<mnemoc> others are junk
<mnemoc> they neglected to add sata and hdmi
<mnemoc> jquip: the h6 is 10" and 1024x600. yones' is 13.3" and 1024x800
<jquip> libv: yeah youre right, a wm8650 netbook did come out with the same outer shell .. its the same design , with the a10 board
<jquip> this has 10'' inch

<jquip> I just dont get it.. why would they not offer linux with these laptops.. they would be so much better to work with.. and to make the android system you still need the base linux kernel anyway... Android for a laptop is such a bad bad business decision..
<hno> jquip, because Allwinner have not understood Linux.
<jquip> they know to make microprocessors!! and they have never worked on a linux machine???
<libv> for that matter, who in that business has understood linux :)
<mnemoc> jquip: they have a ubuntu server for compiling and everything else is windows based
<mnemoc> all code is ^Med
<mnemoc> and GBK encoded obviusly
<oliv3r> that IC+ IC is a 'Mobile Multimedia Broadcast Demodulator IC'
<oliv3r> its sad that these companies work that way, but I guess they don't really care enough, they just want to sell their chips lots and lots
<oliv3r> but I guess having expertise in house (android in essense is still linux) would be much better in the end

<jquip> it does not have radio, what makes you say that...

<oliv3r> hno: IC+ IF101
<oliv3r> near the SD card
<hno> Ah, see it now.
<oliv3r> the datasheet i ffound (could be diffeerent chip, of course) claims that it's some sort of analog demodulator
<hno> That should be the ethernet PHY.
<hno> with transformer on the other side.
<oliv3r> ah, the trxcom does look like one
<oliv3r> and the connector right of the pink one is an ethernet port, i thought it was sata or somesuch, ethernet makes more sense :)
<hno> Can't really read the chip markings on the IC+ chip, but it should be an MII PHY.
<jquip> i can help.. wait ...
<oliv3r> I thought I read IF101A LF 1234C15 CP4F200.00
<hno> Not sure if that's an F A or B.
<jquip> oliv3r is right

<slapin> mnemoc: they are still very angry with me though, cause I come to work late and report nothing for weeks, while department I work in is not that important (hardware development provides far less income than sales), and they consider closing it every year, so I hope I find something cool before they close hardware department.
The-Compiler has joined #arm-netbook
<oliv3r> *facepalm* why are you always late!! :(
<slapin> mnemoc: my paid work, if left as is, would take 24h/day, and the rest of team is very motivated and young (and underpaid), I'm well paid, but very lazy and slow, comparing to them. I resolve fuck-ups fast for them, this is probably why I'm still needed.
<slapin> oliv3r: I can't do anything about it - put any time where I'm required to come to work, and I will be late. I can comply with short-range schedules, but I can't come 12pm every day to work, I can do it for weeks and even for several months, but then it gets into chaos.
<hno> slapin, too much other interesting things to do.
<oliv3r> lol
<jquip> slapin: sometimes it does have a tendency to come and bite you back hard though...
<slapin> oliv3r: if projects are not schedule-intensive and managers don't care much on arrival time, I perform well, but as managers become bigger and try to do what they think they are for here, to get things in order, than troubles start.
<slapin> some people illustrate totally altruistic approach, even spending nights at office before release, even living here for weeks, so I look very unmotivated before them
<oliv3r> ah, you work for some gamestudio :p
<slapin> and everybody have families and small kids, so that can't be used as an excuse...
<jquip> it's true for all research + coding based projects.. you cant really put a number of days on the thing... the same bug which took 3 days to figure out one day can take 15 minutes on another..

<oliv3r> What i ment though, is that what those gamestudio's do, hire young kids, that are motiviated, pay them next to nothing and make them work long long hours

<jquip> I get output , but all garbled output...
<slapin> jquip: check your ground connection
<jquip> is it a good idea to connect to the ttl GND?
<RaYmAn> ground has to be connected for it to work.
<slapin> RS232 grounds should be connected together and to both power grounds
<slapin> otherwise there might be power offset between appliances
<slapin> or other bad things
<jquip> * gulp.. i have connected them both..
<slapin> jquip: check with some instrument
<slapin> jquip: also check if pin 5 is connected to the ground too.
<jquip> i get good signals.. i 've put the machine on android... when i press the lock button i get some signals, when i press the unlock i get a line..
<jquip> slapin: this is the machine pic: http://linux-sunxi.org/File:H6-netbook-mainboard.jpg

<jquip> can't go and get another one soon ..
<slapin> jquip: so cool device
<jquip> its pl2303HX .. it should hold
<jquip> :D
<jquip> okay slapin: pin 4 and pin 5 on the board are GND, so i should connect them both together with the GND on the usb-ttl device??
<slapin> jquip: well, I don't know, but there's lot of bad quality cables on market because someone invented a way to fake pl2302 with some wiched chip which even can't do clocking right
<slapin> jquip: I mean pins of RS232 DB9
mad_away has quit [Quit: Leaving]
<slapin> jquip: shielding, pin5 should be connected on both sides, and grounded on both sides
<oliv3r> you can connect your USB chassis (or PC chassis) to the gnd of the netbook (pin 4/5) and pray
<jquip> slapin: heyy no worries, if its needed, i will get another one... ... but for now, let's just try.. all i have done is
<oliv3r> but i doubt usb -> rs232 gnd is not connected on your cable. might be completly different issue :p try connecting with different baud rates?

<focus_well> Anyone got photos of boards with A10 taken off? I need to see tracks and drill holes. I been looking at all the other photos of boards and I got a pretty good idea where chips can go, but I need the next final step - how the tracks are laid out under the BGA.
<focus_well> Also I not see too many photos of components underside of A10 bga. Some are correct, but one had not many capacitors - that is shocking!
<jquip> In P5 the pins are probably TX, RX, VCC, GND, GND.
<slapin> oliv3r: the shielding is often not connected, and devices power supplies often have no gnd pin hence offsets, so grounds should be connected no matter how
<jquip> ahh okay:
<jquip> right now i am connecting only pin4 or pin5 to GND
<jquip> let me connect both..
<oliv3r> well if you have a multimeter
<focus_well> Actually not having capacitors under the A10 may not be shocking if what the A10 really require is one big tantalum and engineers make mistake about that.
<oliv3r> measure the USB case and the 'gnd' on your rs232 cable/side, should be 0 ohm :)
<oliv3r> otherwise get some wire, connect it to your PC chassis and to PIN4/5
pwhalen has quit [Remote host closed the connection]
<oliv3r> focus_well: there where a bunch of cheap tantalums at the bottom of the A10
<oliv3r> cheap caps, don't think they where tantalums*
<focus_well> The recommended design uses lots of cheap 0.1uF capacitors. All fine and OK. But I see one mboard without capacitors! That had me thinking. May be the design engineers not correct.
<oliv3r> jquip: on the upside, I think if you get a broken identical mainboard, you can desolder the NAND chip and solder it on the empty spot quite easily to double your nand ;)
<oliv3r> if it works (tm) (sometimes its good enough :p)
<focus_well> May be the A10 require a large Tantalum and save cost with not putting in so many small 0.1uF capacitors everywhere.
<jquip> oliv3r: muhahah!! if i desolder and connect it on the other side I get double the RAM???
<focus_well> It if came down to it, I'd have to sacrifice one of my mk802 to get the photos of tracks under the bga. But rather not :-)

<jquip> or mailing list..
<focus_well> jquip: that was my thought - someone may have damaged an A10, or out of curiosity put one in the gas oven and took off the bga. :-)
<focus_well> jquip: Where is mailing list?
<jquip> wha??
<jquip> you're not on mailing list??

<jquip> the old one was arm-netbook but now that's for EOMA related chatter..
<focus_well> jquip: I'm on the EOMA one.
<focus_well> Any good asking there for such photos?
<jquip> yes yes please do..doesnt hurt to ask... EOMA people are more hardware oriented and might have torn a device or two... you might get some ,,,"bah... go to linux-sunxi" but that's okay right?

<Guest52002> is it possible for anybody to point out how I can get the Mali GPU Linux EXA/DRI2 and X11 Display Drivers working with a headless Debian Wheezy with a 3.042+ kernel on the Hackberry device. I would like to get it booting on screen via HDMI connect.
<Guest52002> So I get a console but with the fbdev module.
<Guest52002> I want to build a r3p1 armhf driver to integrate that into my x.org. However, Debian repositories do not seem to have the following two packages:
<Guest52002> libdri2-1 libdri2-dev
<Guest52002> I tried to follow instructions from linux-sunxi's Mali 400 wiki page. http://linux-sunxi.org/Mali400
<Guest52002> but they are written for ubuntu distros
<jquip> Guest52002: try compiling those libraries from source..

<jquip> oliv3r: :D good on ya!!! * pats on the back :)
<oliv3r> lol
<slapin> oliv3r: what is so stupid about ccm?

<oliv3r> it's long and a lot of work
<oliv3r> my typing bone hurts!
<oliv3r> just outing some frustration! I probably have to go over minor fixes sometimes anyway :S
<slapin> oliv3r: it is at least somewhat documented
<oliv3r> SRam controller gonna go up next, should be much shorter. that's for tomorrow!
<slapin> unlike NAND controller
<oliv3r> slapin: it is? other then what I just put up I mean
<oliv3r> well yeah, the nand controller is even more stupid!
<slapin> oliv3r: :)
<oliv3r> anyhow, the CCM documentation is horrible and full of errors
* slapin actually thinks it (NAND controlelr) is too clever clever instead

<steev> allwinner peeps, is there an a5?
<Turl> cortex a5?
<steev> no
<steev> wtf processor does that have
<Turl> steev: >Processor1.0 GHz Apple A5
<steev> right
<Turl> yeah that looks about right ;)
<Turl> :P
<steev> look at the top details though
<steev> it claims to be an "All winner A5"
<Turl> yeah
<Turl> #3 in Computers & Accessories
<Turl> o.O
<mnemoc> actions, the company from which allwinner spinned of, has a quad cortex-a5
<mnemoc> off*
<mnemoc> but that's probably an A10
<mnemoc> didn't know telechips' a5 supported sata
<Turl> the tablet has sata? o.O
<hno> slapin, I think we need to do the same to know how much to read. The two kontrollers are quite similar in many ways even if the bits differ.
<slapin> hno: I see no much similarity, as it directly controls control lines like ALE and CLE, etc, and commands and data are quite well separated.
<mnemoc> Turl: that amazon listing says it has ;-)
<Turl> is Polaroid PMID705x an A10 device?
<mnemoc> Turl: btw, I did finally receive 2 "amazon basics" class 10 SD cards... and, just like the cheap chinese class 10 cards, writing is around ~4MB/s
<Turl> mnemoc: with amazon you can return them at least ;)

<RaYmAn> nice :)
<mnemoc> after two weeks in memphis' post office mine reached NY today...
<RaYmAn> woo!
<RaYmAn> that's progress
<RaYmAn> of sorts
<mnemoc> :)
<mnemoc> i naively had the hope they had forgotten to update the state but it was already crossing the pond
<mnemoc> but no
<RaYmAn> :(
<hno> slapin, page read commands annoys me. Seems to do what they shuould up to 2 sectors, but have to reset the controller to access the result, ram locked out otherwise.
<RaYmAn> Did I mention I took mine apart and reflashed the rootkeys with dev keys?
<mnemoc> RaYmAn: url? :)
CaCtus491 has quit [Ping timeout: 264 seconds]
<RaYmAn> url?
<mnemoc> RaYmAn: no blog post describing the process? :(
<RaYmAn> it's rather easy
<mnemoc> RaYmAn: can you get rid of the scary dev mode warning on boot that way?
<RaYmAn> yep
<mnemoc> neat
<RaYmAn> It's easier than it looks
<RaYmAn> in fact, you don't need to take it apart at all
<RaYmAn> you just need ot take out one screw
<RaYmAn> didn't know that :/

<RaYmAn> It's rather cool
avernos has joined #arm-netbook
<specing> Turl: what?
<libv> i'd guess that the coreboot guys at google lobbied hard for that one
<RaYmAn> it doesn't use coreboot
<Turl> specing: the EC on the chromebook has source code available
<Turl> "Really. Opening the case will allow you to modify the read-only firmware that makes recovery possible. If someone from teh internets says "You need to reflash your BIOS", they're almost certainly wrong. "
<Turl> heh
CaCtus491 has joined #arm-netbook
<libv> there is a difference between actually using coreboot or involving some coreboot guys
<libv> david hendricks has quite a lot of commits in the ec.git, and he's definitely a corebooter
<RaYmAn> of course
<RaYmAn> it also uses DT properly <3
<RaYmAn> as opposed to nexus 10 (same soc, same kernel version)
<mnemoc> this EC supports stm32 too.... maybe we could use it for eoma? (if such thing ever leaves the vapour state)
<RaYmAn> it is STM32
<RaYmAn> on chromebook
<RaYmAn> mnemoc: I'll probably do a quick writeup once I have a custom u-boot working
<mnemoc> :)
<RaYmAn> the chromebook has one of these: http://www.st.com/internet/mcu/product/216844.jsp
<specing> Turl: reflash your BIOS, now!
<RaYmAn> you're kind of screwed if you break the SPI flash
<RaYmAn> well, unless you fancy trying to reflash it by hijacking signals
SouL_ has joined #arm-netbook
<specing> RaYmAn: is it desolderable?
<RaYmAn> specing: I have no idea :) I certainly wouldn't be able to, lol
<specing> I have SPI-capable AVRs around :)
SouL_ has left #arm-netbook [#arm-netbook]
<RaYmAn> ... IlmBuE5UcgmJ-TKR0EftPDaNuvuJ-aZhbXE7jGd-OlXWggg0Pk7QlsXNAa7H4C8&attredirects=0
<RaYmAn> ffs
<RaYmAn> there
<RaYmAn> it's probably easier to do with one of those 8-pin soic8 clips you can get
<RaYmAn> as long as the first 2MB of the SPI is intact, you can recover
<RaYmAn> so all I did was change some flags and replace the keys, then re-enable read-only for htat part
<RaYmAn> but at least I can sign my own u-boot for the RW part and play with it safely
<Turl> specing: I did actually, the other day
<specing> well I think I'll pass this one
<specing> no sata, no HDD, no 100M+ ethernet line
<RaYmAn> yeah, it doesn't have sata brought out - eSata port would have been nice
<RaYmAn> it does have an USB 3.0 port though
<specing> also at $250 it is the same price as intel atoms
<specing> which usually come with 250GB+ HDDs
<RaYmAn> It's targetted at cloud stuf
<specing> Also I dislike the bulky framing
<RaYmAn> given you know, chromeos is a browser-based os :P
<RaYmAn> bulky?
<specing> around the screen
<RaYmAn> lol, I suppose. It's thin and bulky at the same time ;)
<specing> I mean there is literaly 2 cm of plastic at each side of the screen
<specing> and 3 at the bottom
* RaYmAn shrugs
<specing> even my 4 years old x86 laptop isn't as bulky, come on
<RaYmAn> it probably weighs three times as much
<RaYmAn> :)
<specing> EVEN MY CHINESE A10 TABLET ISN'T THAT BULKY
<specing> RaYmAn: agreed
<RaYmAn> but I dunno
<RaYmAn> I think it's rather nice
<RaYmAn> it looks bulky, but it doesn't feel bulky
<specing> RaYmAn: has a billion more peripherals, 32 CUDA cores and an actual HDD
* mnemoc doesn't understand why the crappy screen :<
<specing> maybe if the chromebook were $150 I'd buy it
<specing> but at $250 -- no way
<RaYmAn> specing: but it weighs a lot more, makes a lot more noise, gets hotter
<mnemoc> RaYmAn: how about the battery life?
<RaYmAn> mnemoc: tbh, it's not *that* bad. It's certainly insanely better than adam ;)
<specing> and makes me a thousand times more productive than on some cloudy stuff
<RaYmAn> I don't really have any solid numbers tbh
<RaYmAn> I'm kind of strugling to find ways to properly use-use it ;)
<RaYmAn> I live too close to my workplace to really use it for travel stuff
<RaYmAn> specing: It's a different market I guess
<RaYmAn> It's not intended to compete with bit crap-laptops at 250$
<RaYmAn> it's at most intended to compete with netbooks, and it certainly rocks in that area - even with only 16gb storage.
<Turl> aren't the craptops called netbooks these days? :)
<RaYmAn> I dunno
<RaYmAn> netbooks has to be small in my world
<RaYmAn> lol
<Turl> or is a craptop a big screened netbook?
<RaYmAn> is there any real definition? lol
<Turl> <12 is a netbook on my book
<Turl> 13 is limbo
<Turl> >13 is laptop
<specing> Anyway, has anyone gone through the parts and checked how much of that $250 is real
<specing> ?
<specing> >15 is an UPS'd desktop
<RaYmAn> as in how much it costs to manufacture?
<RaYmAn> There isn't much info on the Exynos5/Cortex A15, so I dunno if you can really calculate it very well
<mnemoc> <=10 netbook; <=14 laptop; else, UPS'd desktop
<hno> specing, agreed. My 15.4 do not quite qualify as laptop.
<specing> mnemoc: :)
<RaYmAn> mnemoc: mm, I don't consider the chromebook a laptop at all at 11.6
<Turl> >=15 is a notebook :P
<RaYmAn> it feels too small
<specing> >=15 is a heavybook
<mnemoc> my thinkpad is 11.6
<hno> laptops are not notebooks. http://en.wikipedia.org/wiki/Notebook
<Turl> "For notebook computers, see Laptop."
<hno> a tablet or large size phone (both with stylus) might be able to realistically claim notebook title today, but not a laptop or netbook.
<RaYmAn> hno: http://www.google.com/search?client=safari&rls=en&q=define:notebook&ie=UTF-8&oe=UTF-8
<RaYmAn> 2. A portable computer that is smaller than a laptop.
<RaYmAn> I doubt you can really say with any particular confidence whether it is or isn't. Language evolves ;)
<mnemoc> you can't call laptop a device that burns your lap, passes most of it's life plugged to the wall and needs a backpack to carry
<mnemoc> carriable desktop with builtin display and battery
* Turl prefers a suitcase
* RaYmAn hugs his IBM PS/2 truly "luggable" "laptop"
