Bios Mods -The Best BIOS Update and Modification Source › Bios Mods Forum › Unlocked Phoenix BIOSes › Acer. Acer Aspire 7520. Bios for ACER ASPIRE. Download and update your Acer Aspire 7520 1.33 motherboard BIOS - PH7L1ACF to the latest version.

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. 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.

(from other topic) I have downloade the Bios recovery disk program, and made a Recovery Disk with version 1.07 of the Vista Bios. (I have no autoexec.bat, no fix.bat, and i didn't replace the plash16 file.) Anyway, this gives the 'best result', the USB-floppy reads the floppy for like 1-2min, otherwise just about 10-20s.

I have the 7520 (one with a Gforce 8400) and have the exact same problem. I tried every way from the but my screen stays black and it doesn't reboot. At this point the only thing I can think of is that the lowest version of the Bios available at acer site (v.1.07) is not the original version (i.e. We'd need lower).

Though, quite frankly I don't think it matters whether you have the original or newer. Anyway, did you manage to fix your 7520? If yes, any tips for me? - Dead Acer Owner. 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. 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 No more Acer for me. I'll buy a case tomorrow to backup the harddisk and then I'll call Acer and act stupid.

This post seems to be useless one year later but i'm so happy that i had to post a reply, just in case someone else have troubles with his laptop. I just succeeded in booting my acer 7520g laptop!! I thought it was dead coz i tried all the solutions that i found with google and none of then seemed to work (fn+esc keys, crisis disk, bootable cd with all kind of bios with many and many different extensions and filename.tested almost all hardware parts.) actually i just have to press tightly near the touchpad to launch the boot, the laptop does not restart every 2 seconds, all works like a charm!! Hope it will help someone!! Thanks ktulm, Didn't think it would work but it did. Tried to open the case to see why but couldn't get it off.

What I did find is that if you remove the motherboard cover, the large one on the bottom, there are two wires, on white and one black, coming from under the battery compartment to a rectangular, component near the speaker. I happened to catch on of these and it came off the componet.
