Acer 7520 black screen during POST
by jecasas - 7/17/12 2:49 PM
My father has an Aspire 7520 and some days ago he told me to install W7 in it.
I came up with the idea of upgrading the bios, as there was a newer version available (1.33). Bios and tool to flash it were downloaded from official Acer web, and flashed under windows.
The update was succesful (or that's what the program said) but from that moment, every time you turn on the computer the screen will remain black until windows welcome screen appears. The computers works fine except for that period of black screen during boot,
This happen with the integrated screen and the vga port (using an external monitor).
I can access the bios but see nothing in the screen... and this is annoying. I've tried to downgrade bios (with no success), also tried to restore system... but i'm running out of ideas...
Any suggestions about how to bring back the screen during post will be welcome...
And if someone has had difficulties understanding my english... well, it's not what it used to be. I hope I have expained myself well enough
Thanks in advance!
