Laptop Keyboard and Mouse is not working properly now. Last time this occurred which was about 3 months ago, I reset-ed Windows 8 and it was all working again. When this occurs, in both incidents, I can't go to bios, can't enter password to login, can't open on-screen keyboard(except sometimes), and even if I get open, using it is same as using the keyboard. Mouse errors: LMB changes to Select all thing so I can't click anything. This issue is same at least most of the time. Keyboard errors: This varies a lot from time to time. I reset-ed OS this time too and the problem still exists unlike before. Ex: I'm not sure this key is this or not, but it was I think Z is ctrl, x is alt, a don't work, ctrl, alt, shift don't work. Then, keyboard itself keep on pressing space or opening windows help and support. And then I updated my BIOS and now the problem was a little bit solved or I think it would be best to say the problem changed bit. Now z,x,a, spacebar, ctrl, alt, shift, everything working,except ! and maybe a few other keys, but now It keeps pressing caps lock, shift and opening up windows help and support. Then I restarted, and now I pressed F2(BIOS) and it let me in. I tried changing the boot priorty order but those keys F5/F6 aren't working, so I restarted, now again I can't press F2. And sometimes laptop beeps for some reason on booting up. There are no keyboard drivers except the default one and sticky and filter are all off. Hope you can help me.
