Acer Aspire 3680 Laptop Display/ Mobo Problem

[mish87]

Hey Guys,
Wsup?

Few Months ago i got an Acer Aspire 3680 Laptop
but the problem is its more likely dead.
ok

• I press the power button and the power led comes up and the fan spins for a while and goes silent,
• Still no post or no bios or nothing on the display just dead black
• so i keep waiting to hear any windows startupsounds but nope nothing
• nor the HDD led blinks so its not booting! or no bios display or nothing
• i tried and external monitor but still nothing
• then i downloaded a service manual and opened it up to see if sme thing was loose
• but evert thing was intact visually
• so i dusted and blew up all the dust inside
• and put it back together and turn it on hoping it will come to life
• but still nope
• same problem persists
• so i plugged in the hhd to my Desktop and used it(it works)
• and yesterday when i was arranging my room i saw it just lie there dead in a corner and thot will try turning it on again
• And voila it did turn up and i got into bios n stuff but it had no hard drive so cudnt go to windows
• but wen i saved and exited bios
• it again goes to staying dead
• and one thing i noticed was the lcd was dim even wen i tried maxing out with fn key n brighten key.

Has any one come across this, is this a mobo problem or a display chip or what ?

i tested the ram and the hard disks they work perfectly.

it cant be bios corruption, cus i tried flashing in new bios for the model from acer too

one guy says its a loosened or burned display chip

O dunno whats wrong?

please help me bring back the poor thing to life

Thank you!

I think some power problem. Not sure just check your power input.

I second INDRANIL. You should check the power supply. Something might be wrong with the BIOS too. Remove the CMOS battery , wait a couple of minutes and put it back again. Report back here.

i tried pulling out the cmos battery for a few minutes n back but no luck.
but how do i test the power input ?
i dunno
is there a tut anywhere?

Your case is a weird one. I don't know what else to say...

i have face that problem with my laptop also. its the display chip problem. your VGA chip is not working. change the display chip and your laptop is back online

You are hopefully aware of how hard it is to replace a chip is on a laptop, I hope...

Can you direct me to a link or somewhere, i can do this , like a tut or something...
i want to try this, i guess its a chip prob as well.....

BTW:
one guy asked me $80 at a local it store to fix it,
he says heknws the problem, and says its common in acer laptops...
but when i asked him if it was the chip or the power he wnt tell me wats wrong,

The same prob occured to me except my bios screen came but no display after win xp loading screen comes, second mine was an acer desktop. To fix it I tried re-installing but to no avail. Even tested ram and removed cmos but to no avail. Angry i tapped the graphic card(the golden part) with a pen ,rebooted and voila it worked like a charm. If no bois is coming I suppose its a faulty ram. does laptop give any beeps while booting. Try replacing the ram. My computer always crashed with a BSOD and I figured it was a faulty ram. Dont trust the local computer engineers the may looting you. Infact they may even further damage your computer.
