Windows 7: Keyboard and Mouse Sometimes Inactive at startup

Hi all! In searching for solutions, I came upon this site and think it's just great. After reading some of the posts, I have to be a member immediately.

I have been experiencing problems recently with my pc. For clarity, I will list them:

1. For the past 2 to 3 weeks, my usb keyboard and mouse are inactive at start-up, therefore I am unable to login and go any further. I have to turn off and start again. After several turning on and off, it might work.
2. I usually unplug my computer when I am not going to use it for some time (e.g. overnight) and although I properly power down before I unplug, I notice that as soon as it is plugged in, it starts to boot. This never usually happen. I should be able to plug it in, THEN turn it on whenever I want , as I used to do. This is also when the keyboard and mouse are inactive.
3. Whenever this automatic boot occurs, and I turn on and off many times until the mouse and keyboard become active, my date and time always revert to sometime in 2002.
4. The pc has also become very slow.

Please, I really need some help asap. I cannot afford to have this computer completely fail. Thanks much.

Hi Welcome to Seven Forums ... Look in your Bios Settings for an BIOS option auto power on after unexpected loss of power ... Should be in Power Options .. Looks like your Battery could need replaced ... There could be many other faults you have .. But lets see how that goes first ...

Thanks much for your response. I checked and it says "enabled". What next?

Disable it that should resolve that issue .. Report back then how your USB Ports are working ..

Your clock going back to 2002 when the power is unplugged is usually a sign of the CMOS battery being bad. It's usually just a small watch battery on the motherboard and you can get them just about anywhere. As for the KB and Mouse, when the bios reverts back to default the legacy support for USB could be getting set to disable.

Additional info:
During one of my many tries this morning, a screen came up showing specs for my computer but with the keyboard and mouse inactive during that time (and this was shown only for a split second) I used my camera to snap what was on the screen. I notice that a line at the bottom says about "Unknown BIOS error" etc. I am going to watch for this again and capture more of what is at the bottom of the screen. In the meantime I've attached what I was able to capture.

See if you can Post a screenshot of the Error .. The Link below will help you achieve this ..

Sorry, I uploaded a file with the last correspondence - don't know what happened to it but I'll try again. Please remember also, that the message came up while the keyboard and mouse are inactive, so what I captured was with a camera. I am also going to send my BIOS power setting.


Thank you Shawn, I'm sure this step by step should work now.

No problem what is the Error Code i can not see it proper ?

Sorry it took so long but I just got the opportunity to see that the error code is 0012. Two lines of additional information is below that but I couldn't catch it quickly enough. Will try and get that soon.
