Hi
it is not advisable to replace cmos bettery on your own if you are not aware of opening notebook
because each and every notebook wil lcome with its own tricky fittings
so if you dont know how to open your notebook
just go to ant technician and let them do it for you

Does this P.C have an internal battery, and if so can it be changed


If you mean a BIOS or Backup cell, yes, akk OC's have. We cannot comment on how to do it as you don't reveal the make and model.

AFTER SWITCHING ON, SCREEN STAYS FROZEN AFTER SAYING CMOS CHECKSUM ERROR- DEFAULTS LOADED


Hi there,

When starting your PC, the following error message is displayed:

CMOS wrong
CMOS MEMORY size WRONG
CMOS Checksum Bad
CMOS checksum error defaults loaded
Warning! CPU has been changed please re-enter cpu settings in the cmos setup and remember to save before quit!
You are prompted to:

Press F1 to resume
Press F2 to load default values and continue


This is due to the fact that the CMOS, which contain data related to the BIOS, has been reinitialized and that your PC has been reset to factory settings.

Solutions:

Reinitializing the BIOS
  • Change BIOS battery
    • If the problem persist this may be due to the fact that the battery powering the CMOS (when the computer is shut down allows the CMOS to store information), is depleted.
    • The CMOS battery is a small pin found on the mother board, you can refer to the manual provided with your motherboard to change it or have the nearby computer technician change it for you if you don't want to risk any damage.
    • More information with: Replacing the battery of your motherboard (CMOS battery)
Post back if it is not working we will be happy to help you.
Hope this helps.
Cheers!!!!

How do I replace a dead cmos on acer 4520LCi travelmate laptop? The laptop no longer keeps track of system time when shut off completely. Can you tell me the exact location of the cmos so I can be able to...


Hi,

what you replace is not the CMOS, but the CMOS battery.

On an ACER from those years the CMOS battery looks like a coin, or a coin wrapped in plastic and connected to the motherboard.

On most models from same series the battery is located on the lower side of the motherboard, like on picture below:

On some model the battery may be located underneath the keyboard.

Here disassembly instructions for a similar model.

Try it with only the battery.
Try it with only the power cord without the battery.
If neither of these work, you most likely have a bad motherboard.

Cannot Boot


Removing the cmos battery isn't always enough to reset the bios you may need to find the 'JBAT1' terminal on the mobo and put jumper across pins 2-3 then back to 1-2. But it may be a faulty mobo where the charger connects to the board.
