acer aspire v5-571p 6815 bios password

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 this http://community.acer.com/t5/V-and-VN-Series-Laptops/No-access-to-BIOS-Aspire-V5-571G/td-p/157643/page/5

"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!!

If you can get it to boot from a USB,

For "Operation System not found", Check if the setting in Boot tab has changed from UEFI.

On the Acer Aspire V5 series, if you open the bottom cover and remove the RAM you should find a couple of pads on the board labelled G2201. Remove the battery and power cord from your machine. Use a piece of wire to short those two pads. While holding the wire, plug the machine back in, then hit the power button. This should clear the password. I had to do this a number of times, but what finally worked was to hold the power button down while the machine came on, then shut off. I cycled this a few times then eventually the password was removed and I was able to get into the BIOS setting screens. Good luck!
