Acer Aspire v5-571p-6815 Stuck with Bios Password


Oct 23, 2010
I've been struggling with my laptop for about 5 hours now.

It was working fine with Windows 8 and I wanted to reinstall the laptop to Windows 7 due to virus.

But pressing F2 didn't get me access to Bios. I noticed that some Acer Aspire V5's can't access Bios as it's hidden/locked so I was surfing webs to find solution and I stumbled upon thishttp://

"The Accepted Solution #1" says download the unpacked bios image then run it through the command prompt. Which I did and F2 did get me to Bios but I faced a really big problem. It's asking for Bios password.. I have never setup Bios password to begin with..

I can't get past this screen. I have tried disassembling the motherboard to pull out cmos battery for 5 minutes and didn't work(I broke my screen doing this). I also tried shorting the password gap(G2201) and this didn't work neither..

When I try to load OS normally it says "Operation System not found"

I'm stuck and I have no idea what to do.. I'd appreciate help!!
