Hi guys!

I have an old aspire 7720z ick70. I tried to update my bios from 1.14 to 1.45 and while the flashing the device stops suddenly. I wait for a couple of hours and nothing works (tochpad, keyboard, power button...) so I get the battery out and get it on again. Now nothing works (power button, power leds...nothing).

Searching by forums I have found that there is a key-treak to wake up the notebook and re-flash the bios with a usb pendrive, but I can´t found the treak for my device.

Could somebody help me, please?

Thanks in advance.

P.S.: sorry about my english...I think is not so good.

(Acer Aspire 5515) I was checking outthis BIOS updage instructions and cant seem to figure out what files to place on the flash drive or what to rename them. My situation currently is that I get the black screen of death and I cant update in Windows 7 Ultimate which I currently have installed.

It would be amazing if you can help me for I have been at this for days.

The files in the bios zip folder are:

CK MS-DOS Application

Flash32 Application

KAW6100 Windows Batch File

KAW6100.ROM ROM File

KAW6100.WPH WPH File

phlash16 Application

readme Text Document(contains no instructions)

Thanx in advance for anyone who can help!
