Acer Aspire 7520, Black screen.

Hi everyone!

I have an Acer Aspire 7520G. When I installed XP on it, Vista was preinstalled, I managed to accidently flash bios from Windows. When the program started to reflash bios, it stopped somewhere in the middle and the computer died. I could move the mousepointer, but that was it... When I then tried to reboot, the screen is just black. No starting screen or anything. Just black. I can hear the hdd and cpu workng, and the fan is spinning. So nothing wrong there.

So, i've been reading the Acer-thread here. And tried almost everything there. So i'll try to make my own thread, before my last resort, sending it to Acer! So, if anyone has any ideas, or think they know how to do it. Please tell me.

Currently it's 4 versions of my bios. All of them contains both a WPH and a ROM file. (So it wont fit on a floppy). And i have managed to get the computer to read a recovery-floppy(with either a WPH or a ROM file.), But when it stops after a few mins. It never reboot itself... I've been trying with and without the hdd.
Well, thats all the info I have.
All hels is appreciated!

//Regards Fwosth

Ahh, flashing from Windows seems to be asking for trouble...

I was afraid you'd say that.

Just gave it my final attempt. Same story, I get it to read the usb floppy drive for about 1-2 min and then it stops reading but doesn't reboot. I've been at this point with all 5 wph bios available at Acer (1.07,1.11, 1.21, 1.30, 1.32) and after a manual unplug->plug->boot it still ends up with merely a black screen. Crying or Very sad

I've been flashing loads of devices for 20+ years and this is the first one that fails so badly I can't recover it, making this also the worst system I had so far. The specs are nice for the price but the machine sux Smile

No more Acer for me. Neutral

I'll buy a case tomorrow to backup the harddisk and then I'll call Acer and act stupid...

Tnx for the reply and good luck with yours.

Thanks, but as you could have read above we already tried all the methods described in that topic and it's not working for our model.
