How can i reset bios if...

...I cant see the screen? I know my Acer has a restore defalts F-key but i cant see what it is.Long version; I changed an option in bios that had to do with selecting PCI or Onboard. I changed it to Onboard, and now my computer screen stays black, although i know it is still booting up normally, and i can still get into my Bios.
I found a guide online about removing the battery on my motherboard... But i dont think i want to try that yet :(How can i reset bios if...
Looking inside the PC at the mainboard, there is what is called a ''Jumper Switch'' within no further a distance than an inch away from the battery. It is used to ''Clear the CMOS'' of mistakes such as yours. It has three tiny pins, and the normal location of the jumper device's is called the DEFAULT setting. The jumper makes electrical contact between two of the pins at a time. If the battery looks too hard to remove (it's not, not really), you can move the jumper to connect the other pair besides the default pins. If I recall correctly, you leave the ''wrong'' pair connected for ten or twenty seconds (perhaps you need to hit the power switch as well, I'd have to check the individual MB manual if I wanted to do this myself; and you have the leave the little battery out of its socket for a lot longer, maybe an hour, maybe even overnight -- I've forgotten now). Then, you return the jumper to cover the default pins, and the BIOS's settings are all back to their normal starting point (also referred to as ''Default Values'').Your mistake is relatuvely common, as is forgetting a hardware log-in password, so there are a lot of pages like the one below:http://wiki.answers.com/Q/How_do_you_reset_the_BIOSHow can i reset bios if...

I wont lose any information on my comp im hoping...

The vast majority of PCs are running just fine on their default values. Only the enthusiast PC owners are likely to want to tweak various settings to attempt to increase the overall efficiency or top performance of their systems (BIOSes are where the majority of overclocking settings are accomodated).
