Where is the Bios Chip located aspire1700

hi all
have asked before but as yet no replys,
anyone know where the bios chip (surface mount) is located on an ascer aspire 1700 motherboard??
managed to find a pic of the board so if anyone can let me know which is the bios chip would be helpful
thanks in advance
steven

 

Well, why do you want to remove the BIOS chip ?!

 

Hi.

might be the chip with the white label on where the battery plugs into the board with the letters 5L on it.

If the chip is in a socket it`s most likely it!!

 

in answer to firs question, flased bios went bad, now lappy just wont boot, have used usb to try and reflash just dont want to work, blank display no post or anything,even on external monitor,
second answer, i thought that two, but acer says it is surface mounted,not pull out, have checked all over for diagram showing chip locations on m/board, to no avail, was going to remove it if i found which onw and see if acer would send out a pre programed one and re place, know its going to be hard but as nothing working at moment not got alot to loose, if it works great,if not will sell as spareseverything else works (or did before bios flash) screen , inverter h/drive/floppy/cd/dvd combo,most prob get more breaking it judging by ebay prices than its worht working, but would like to get it up and running if only to prove it can be done, acer will reprogram if i send whole laptop to them but £30 each way postage plus £50 reprogaming is well over the top , bet the chip only cost a few pence(or pounds) so its got to be a cheaper option

Your notebook's BIOS chip should be in the form of a 32-pin PLCC package. You'll need special tools to remove it. I don't have the SG for your notebook, and the manual won't indicate where the BIOS chip is located. So its upto you to find it.

A 32-pin PLCC chip looks like this:


I think you should try removing these two chips, possibly the one right next to the DDR socket in the image.

 

also forgot to mention there is this guy who recons he knows how to do it ,but tells you only half truths, sort of goes the long way round thinking its stolen,then when reading posts he sent, looks like he wants money for help to fix it (via help writing an autoexec.bat file)check it out yourself on my other post.
help with acer bios urgent see what you think

 

thats quite like the socket chip with 5L on it ,in fact thats the only socket chip on the board, thanks for the help will call acer am and see if i can get tec support to tell me where it is, have asked before but the guy didnt know or was,nt sayin, at the prices they charge can understand why
steven

 

I doubt Acer will help you replace a BIOS chip. They will press on a motherboard replacement.
Search BIOSMAN on google and see if you come across some useful info there. PLCC extraction tools are available there.

 

Cheers andy will do
steven

 

I suppose you have tried the recover information below!

http://www.biosman.com/biosrecovery.html

 

yes your right andy acer want to replace the motherboard just got email from them today
steven

 

ok andy have taken off the botton sticker think it had 5L on it, it would seem that although its a square socket it has something round init so not bios, the only other is that at top right just behind mem, and that is solderd to the board, so guess that that is the one acer were sayin that it is fixed to the board so guess thats going to be tricky getting off, but dont want to start till 100% sure that ,that is the bios, and i can get or order a new chip ,(programed i hope)
steven

 

hi tinderbox
yes i have but they dont cover alot with regards to a Phoenix bios i have email em with details waitin on reply
thanks
steven
(still no up and running)
i have however found out that (andy,s post) the bottom chip with the L5 sticker, is not the bios when i removed the sticker its a square something or other wit a round bit fitted, so guess the one (see pic) at the top may be the bios and its fixed to the m/board,so prob so job to de solder and remove, but dont want to do that untill 100% sure that it is the bios and i can get hold of anotherone (hopefully pre programed)
thanks for the tip tho
steven

 

Check out these links:

AS 1700 MoBo - http://cgi.ebay.com/Acer-Aspire-170...ryZ60265QQrdZ1QQssPageNameZWD1VQQcmdZViewItem

(Cheaper than Acer I guess...., and later you could fiddle around with your own MoBo)

 

cheers andy but US $249.00 plus postage to UK is to much to pay (laptop was just a bit more than that to buy (was working then) not really ready to give up on it yet tho
,i have located somebody near me with the same laptop, would i be able to get his to write bios code to floppy, might help if i got a chip, or is there some way of connecting his acer up to mine and getting it to flash the bios again? via usb, serial or something else??
just a thought
steven

 

if we can't find a working BIOS RECOVERY METHOD, you will have to either buy a pre-programmed BIOS CHIP, or find someone with a chip programmer that is compatible with the type of BIOS CHIP your motherboard has.

i've programmed many DESKTOP chips, but i don't have the hardware required to program a chip with connectors on all 4 sides.

your best bet might be to contact an AFTERMARKET BIOS supplier like BIOSMAN.

 

Have been looking at the m/board and just wondering, is not american mega trends a bios maker?
if so the large chip in the top od the diagram (see andys post ) has loads of legs far to many to de solder)
has printed on the top of it

SMsc
LPC47M192-NC
BO243-C8482
8H113463F
AMERICAN MEGATRENDS
STA SINGAPORE

any thoughts on that chip???
steven
ps if it is the bios i,m f&c%ed
cos there is no way I could get that off or put another one on so guess thats why acer say get a new board!!!

 

Out of the two chips, check which chip has 32 pins....9 pins on two opposite sides, and 7 pins on the other two opposite sides.

 

cannot see any other chips with bios names on then & wouldnt have thought that they would put american megatrends on anything but a bios chip, and they support Phoenix bios i think?
steven
any other thoughts????

 

that chip would be the top one you highlighted, the other with american megatrends , god has 32 or more on each side
steven

 

the one you highlighted in dig top rigt has
sst
49lf040
33-4c-NH
0319077-BA
printed on top
9 pins both of 2 sides, and 7 pins on the other 2 sides
it is situated just below & to the right of the megatrends one
steven

 

The chip with american megatrends should have nothing to do, since your notebook has a Phoenix BIOS where as that chip indicates that it has AMI firmware on it.
The other chip on the top, should be removable, check this out.



If you can find the extraction slots, then it maybe possible to remove the chip. I have never heard of PLCC soldered chips, and I removed one just like it on my Dell D630.

If not possible, I guess a mobo replacement is maybe the only option you got.

 

didn't Phoenix purchase AMI??

i still think the socketed chip is the BIOS,, but the AMI chip makes me wonder.. has the original poster ran PC WIZARD to see if it says the BIOS is socketed??

 

Actually PLCCs are not shown as socketed by PC Wizard. Same for my 3680 and D630. But the chips can be removed. I don't know, I've only heard SOIC BIOS chips coming as soldered.

And I guess Phoenix bought Award, not AMI.

 

you're right it was award they bought....

but i'm pretty sure PC WIZ shows my bios as socketed... if it is true or not i don't know... i've yet to do a full tear down

i just did a screen capture showing that my bios is socketed.. see the attached jpeg

to get to that screen just double click the motherboard icon on the left window and it will pop up a motherboard info screen on the right..from there double click the BIOS line at the TOP right windows and then in the bottom portion you will see the BIOS VERSION, and below that the BIOS SOCKETED: YES

don't doubt the bigO... i've probed the info these hardware programs have... and i try to keep up with what i can...

 

Just new it would,nt be my day, when i saw the pc wiz screen new i had that installed on laptop and had run it , so have pulled the h/drive and conected up to my pc , found what i was looking for a print out of the mainboard, saved it as text file, dont think you would be interested in all of it just the bios text , see below:

the bios is not socketed its solderd, just new i would,nt be that lucky,
steven

 

looking at what it will boot think my only option is to get it to try and reflash via cd rom, seems the only thing its trying to read when you power on at the moment, any ideas as to how to create one?
have downloaded a prog called CrisisDisk but thats to make floppy,not cd , i think the prog PHLASH16 is selfbooting, have just copied over what was on floppy to cd but did not work, am i missing something ,combination of keys, have tried Fn+B/Fn+ESC/Win+B, do i need to get an autoexec.bat file to tell it to run phlash?, trouble it dont know what to put in it let alone write one
well had enough 1:57am here now, going to get some sleep
thanks to all who have & still are helping
steven

 

PLCC - not soldered, removable.
Weird thing is that all 3 notebooks 3680, 5315 and the 1700, have 32-pin PLCCs. But it is maybe because of BigO's BIOS utility (Insyde) that maybe conveying information as socketed. (Whereby socketed BIOSs are only available in desktops, in laptops they are surface mounted)

Its upto the OP now, whether to try an extraction, or swap the MoBo

 

Andy
today I have spoken to tec support at acer, would,nt belive what they want to first asses then repair, so not going into that, however have found out that the bios chip i need to replace (or repair) is the one you were talking about with 9 pins and 7 pins(top right hand in dig) so now need to sorce one if them chips and if poss get it programed, i am assuming that the chip once flashed with the bios program will contain what it need to work,so will contact mr bios and see what he says?
will keep you all informed other than that any body who has a busted aspire 1700/1710 mobo want to get rid of will buy from you drop me a line & let me know
