Hi, I have question about your post CQ62-220 intel version, your good bios image 1484.bin, as you posted, is the same as bios F37 from website (you tried at beginning).
I compared your bin with fd file from website F37 image by command fc /b, there are no differences. This image makes my CQ62-220ec running with blank screen. Can you help me please? Have you tried reflow of GPU before ? Thanks, Petr

Re: Presario CQ62 Dead Board Help
Hi ,
I have same bios issue as Speedypro, CQ62-220sa with M/B AX35E.
Mainboard was totally dead, charging LED not lights.
I have removed bad flash chip EON EN25F80 8mbit , and replaced by new
flash chip programmed by F37 version.
Now M/B is charging, LED lights, system is ON doing POST, but blank screen.
POST is ending on POST code " C7 - Initialize notebook dock late."
Any idea about this code, please ?
