Acer Aspire 5920 Black Screen

Grogs56 — Sat, 31 Aug 2013 20:20:09 GMT

This notebook is suffering from a black screen on start up. After a minimum amount of research this appears to be quite a common issue which can be fixed by reflashing the bios! I have downloaded the relevant file from the Acer Download section but the dos file is missing, can anyone help with this missing file?
Cheers
Stephen

I would really like to know where you are seeing this information about flashing the BIOS to correct no display, please.

Have you attempted to connect an external monitor to the system?

I too am interested in this BIOS reflashing to cure black screen, because to be honest

I have never used a BIOS reflash to get the screen going. I've managed to get screens

going with drivers, screen replacement, inverter, motherboards, heated up MXM

cards in the over, etc, but never a reflash

Maybe this is a new trick for an old dog to find out about.

Hi this is one of the links which is suggesting a bios flash as a cure for a Acer black screen....Check out this video on YouTube:

If you can supply any other fix I would appreciate any help...

Hi Tommy
I have connected the 5920 to a external monitor and get a normal start up window for approx 10secs, and then it reverts to a black screen...the laptop screen is black from power up?

I watched the vid at the link you posted and found it interesting. I don't know, but I

have had probs with something like this and it was the graphics chip needing to be

"reballed" back into the motherboard. Acer's get hot as do most all lappy's and the

solder that connects the chip to the mb breaks down somewhat causing the

two parts to fail to interface with each other after the unit starts to warm up.

It's just too bad it's not an MXM type board where you could either heat up

the card in the over to reseal the solder or just replace the card. Also it's really

critical that the cooling radiator be clean and decent thermal paste be used

on the chips. Sure makes a big difference.

I hope it isn't this, but there are company's that reseal chips to boards or there

are used boards avail with warranty's on ebay.

N2gc Thanks for your reply, the actual model is Acer Aspire 5920-5A2G12Mi...it doesn't have a seperates graphics card! I was wondering that if I bought a seperates graphics card and installed it, would this override the on board graphics and basically cure this issue?
Many thanks
Stephen

I don't know where you would install it unless that board has some terminal

that allows extra cards. The card as you know is integrated with the motherboard

and it might just be that you'll have to decide if it's worth having a company

to reseat the chip into the board, go for another, board or maybe... use a USB

powered external graphics card if such an animal exists, to cure your lappy's

graphics.

It's not cheap anyway you look at it, but were it me, I probably go with

a used motherboard with a warranty even though most warrantys are

only good for around 30 days or so. But not all is lost. I'll pm you a link

as it's against forums rules, I believe to link such ads.

Could you recommend a new m/board?
