Other Problems and How You Can Fix Them Yourself

Here are some other things that might be a problem for your computer.

Defective power socket

The DC Jack (power supply socket) shows no damage and the current is there and still your notebook will not boot? Especially with systems that are older, the power supply socket/charging socket often is worn out because of constant plugging in and out. This website will offer you the spare part that is suitable for this problem and will correct possible errors that stop the device from properly starting or booting up.

Empty CMOS RTC battery

Your computer is not saving the bios settings? This situation is often linked to an empty or defective CMOS Bios battery. In majority of cases, the CMOS battery is only plugged and not soldered. By just replacing the CMOS Bios battery yourself and use it as you are used to is the easy way.

CMOS error and causes

Has your PC, computer, tablet or notebook suddenly stop working?

Are BIOS settings reset after each boot up?

Error messages

Will you get an error message after starting such as:

  • CMOS Checksum error
  • Invalid Date and Time
  • CMOS configuration mismatch
  • CMOS settings wrong

If you are getting these error messages, then the error is possibly due to a defective or empty CMOS backup battery.


 The term CMOS stands for Complementary Metal-Oxide-Semiconductor and is a memory module/battery where the bios settings for your computer are stored. If the CMOS battery is defective or empty, the settings for the system are reset at every start, and this result in one of the above error messages.
