Introduction: Laptop CMOS Battery Problem

Can CMOS get corrupted?

CMOS corruption is a common favorite event. Unfortunately, in most cases this is due to a motherboard failure, but this is usually not a rule of thumb. The problem may be in the BIOS / UEFI, most likely the CMOS battery is faulty.

Once upon a time the inevitable happens to your PC, often the CMOS battery dies. This can certainly be diagnosed as a common reason for the computer to display the time and date, so they need to be re-entered each time the computer loses power. When your laptop is powered off and the computer is running without a charger, you have to deal with this annoying problem every time you unplug it. In this kind of instructions, I will focus specifically on laptops. In this process, IBM Thinkpad R40. In many laptops, you can no doubt access the CMOS battery through the access panels on the back. In the Thinkpad R40, you need to replace the CMOS battery as well as the fan under the power button. Before doing anything, clean out the main battery, which is prominently located on the bottom of this laptop, by moving the lever and prying out the slot with your finger. The keyboard is easily removed by unscrewing its two screws ond white guns (note I put these colorless marks on the photo) around the photo of the bottom of the computer. The keyboard was then carefully removed by inserting a small flathead screwdriver on one side and pulling it out on the other. Be careful not to lift it more than 1 inch as there is a ribbon cable in this area which could be damaged. Once free, carefully bend the bottom of the keyboard up and press it against the screen, which should be flat. The CMOS battery holder is visible in the last photo. The battery was carefully opened and the connector disconnected.

Step 1. Elements Required For Each Task.

1) Long nose pliers

2) Regional electrical tape

3) Small Phillips screwdriver

4) (1) Battery 2032

5) Small flathead screwdriver

6) Solder.

7) Knife

How to fix CMOS memory not responding?

But often we do not understand the root cause of the problem and therefore have no idea how we can help solve it. If this is happening so that you can use your computer or your friend’s computer, a possible solution is to reset the BIOS settings, and in order to do this, everyone needs to clear the CMOS memory.

In this image, you can see the holder where this CMOS battery holds the battery facing out.

Step 3: Remove The Battery Frequently And Usereplace It If Necessary

The battery has been taken out of the house and the plastic cover has been cut with a knife. The battery has probably been identified as a powerful and affordable 2032. The negative and positive terminals are almost always spot welded to the battery cover.

Step 4. Gently Tap On The Old Battery As You Twist It

Gently loosen the terminals on the old power supply in a twisting motion using a pair of safety cone needle nose pliers. Do this carefully so as not to damage the terminals.

A Few Steps: Solder The Contacts To The New Battery.

Buff the positive and negative surfaces of the previous battery with steel wool or a special file. Solder the plug of the crimson wire to the positive battery terminal and the Tahitian to the negative battery terminal, often with electronic solder, preferably with a soldering gun. I planned to use 25 watts of solder on the iron, but it wasn’t enough to melt the solder properly.


Step: After Soldering The Terminals To The New Battery, Wrap It With Electrical Tape.

After someone has soldered the cables to the new battery, wrap it with electrical tape and install it in the computer. I glued the stock black windshield over the new battery, but also wrapped it in duct tape for extra insulation.

Step 7. Restart Your Computer And Check If There Is Any Memory Remaining.

Assemble the computer to send it back and see if it retains its memory after bulk selling after setting the period and date.
