Start up problem: Acer Aspire 7520

Syndrum² · 2014-02-07 15:12:41

hey, I have not used the laptop for 3 years because i bought a new laptop the last time he worked as far as I remember
Now the problem is when i press on the power button i hear the fan for 2 seconds and then stops
The screen stays black and 3 lights continue to flash.
I do not know what that means, but the last time he was still working perfectly
and now no longer out of nowhere!

bios battery might be dead by now but not sure lost settings would stop it from booting?

sounds like a motherboard issue

I looked at the battery it is not replaceable the battery is stuck on the motherboard.

those 3 flashing lights can be a error message from the power on self test (post) try google on "bios post message (your computermodelname)"

maybe i dont know i have read on some forums that the problem is the cpu,
but i do not think so because all the lights go on.

Anyway, Syndrumpep...

if the question is "can I solve this by me"

the answer is no.

Good luck with assistance

It seems you are not alone then that blinking should be a fault message, see if you can find it in the manual

edit: if nothing else helps you can try "bake" method, back in 2008 nvidia changed to lead free soldering witch caused a lot of problem http://www.theinquirer.net/inquirer/new … -defective

there is some reading here about the issue http://www.techsupportforum.com/forums/ … 43165.html

it seems the nvidia card is a plugin modul so i would try remove it and bake it if everything else fails

iwe done it with a geforce 8800 gt card once

I have read in many reactions that they have removed the motherboard,
and they have put the motherboard in the oven with 200 °C for 7min and have solved the problem :0
I'm going to try that in the night

There is nothing wrong with the video card, because screen turns on, only stays black..

The problem was the nvidia chipset i've warmed up to seven minutes with a hairdryer
and let it cool for 10 minutess and he did it again! sounds a little crazy but it worked!
