On desktops, it’s easy to get to, and it’s only held in place with a metal clip. On laptops, you’ll need to open the machine up to get to the motherboard, and that might be better left to a professional. Restore settings that may have changed as a result flashing the BIOS. I’ve been working on an older HP Pavilion XE743 with Win98SE and an Asus MEW-AM motherboard with 810E chipset and socket 370 that has Phoenix BIOS. Does your motherboard have a jumper switch on it to reset the BIOS?
If the BIOS was recently updated, the CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings.
If a virus has updated the BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default. If the cause is a dead battery, all you need is a new one. The CMOS battery is located on the computer’s motherboard.
Maybe you could try that & see what happens. You’ve got to try to get into the BIOS somehow. I don’t think your board is going to even attempt to boot off anything (CD/hard drive/etc) if it’s getting stuck during the BIOS startup. My experience of Gigabyte boards has been quite a negative one, and every time it boils down to BIOS problems. Have you tried seeing if there is a BIOS update?
The jumper position, time to wait, and location of the jumper are completely dependent on the motherboard. and my learn this here now computer shows CMOS Time not set error with checksum bad error and usually auto reboot after some time.
I can’t really run anything because my battery is dead so it starts up and immediately gives me a critical battery error and shuts down. It’s possible that the problem is just caused by the CMOS battery being dead. The simplest test would be to replace it with a new one (they are pretty cheap to buy).
Unfortunately, not all CMOS batteries are removable; some manufactures will only allow a replacement battery to be added. Locate your CMOS battery – Find the battery within your computer and ensure that it will be accessible and that it can be removed. Most computers today use a coin cell CMOS battery; an illustration of commonly used CMOS batteries can be found here. If you are unable to locate your CMOS battery you will need to contact your computer manufacturer.
Normally there are two other things that cause your problem besides the CMOS battery. I had the same problem fixed it by replacing the battery. The way i figured mine out was to remove the power cord from the psu for about 5 min. When i restarted all my settings were back at default. Go back into the bios and check the settings for your Harddrive, and boot settings.
Helped my dual Athlon MP board when it started suffering random BIOS issues. In my Googling, i came across one chap who said removing (and replacing 10 minutes later) the cmos battery fixed him. If possible, remove the battery and take it to the location you plan on purchasing a new battery from.
