Updating laptop cmos bios
I guess I'm going to need to bite the bullet and pull the PC apart to make sure the battery connections and the pc board traces are good. I have three other computers and do minor repairs to computers my family has, so I am familiar with basic servicing.I checked the battery with my meter/battery tester and it's fine. I've also replaced CMOS batteries in my other computers with no problems. I've run a hard drive test utility many times and other tests, and all seems OK. I never had this many problems with my HP, Dell or Compaq computer.More specifically, it enables you to use the keyboard, see a display on the monitor, access the hard drive or CD drive, etc., all without the need for an operating system.The BIOS is the software that carries you from the moment you power on your computer to the point where the operating system begins to load, providing the instructions necessary to access the hard disk, memory and other hardware.By the way, I appreciate everyone trying to help me and doing so so quickly.Everything appears to be asked and answered already and this appears to be a weird problem.The lazy solution for now is just to leave it plugged into a surge protector like I'm doing.This surge protector is also a UPS power supply so even if the power fails, I have time to shut down and the CMOS memory will probably hold.
It seems it uses a little power to keep the cmos memory in place, even if there are problems with the battery circuit. It often will not start then it runs the repair utility, usually System Restore, to get it going. I know enough about computers to have a good anti-virus and firewall in place and a repair program; I use System Mechanic Pro.This is why you can restore your BIOS to its default settings simply by removing the motherboard battery for a few minutes. The motherboard manufacturer provides a file which will overwrite the default file on the CMOS chip itself, providing the motherboard with a new or updated set of controls. I then rebooted and corrected the date and time, loaded and saved the factory CMOS defaults, and the computer starts fine. Unless the computer has been subjected to a power surge I can't understand why this should be occurring. (usually the ' ' side of the battery should be face up). (I'm a retired sound and communications service tech. I replaced the battery on the motherboard after first unplugging the computer. The negative contact in the battery socket may not be making contact. You could also check with Gateway to see if there is a BIOS update to address this problem. Did you check that the new CMOS battery is the same way up as the old one was?However, if I turn it off and switch off the power strip, the CMOS memory is lost and I must repeat the process. If it's inserted the wrong way up it won't do any harm, but neither will it be able to do it's job. I'd better know by now which side of a battery is which! I did also notice how easily it is to bend the contacts.
