It is unlikely to be the cmos battery as there are signs [music] that your laptop is booting - shine a light into the screen if you can see an image but it is very dark then it is likely that the screen backlight is not working. If this is the case the most likely causes are a faulty inverter or a faulty screen cable - both can be obtained as a kit quite cheaply on ebay if you have the ability to fit them.

How do I remove the backup battery from my Thinkpad 2647 T23? I'm trying to remove the POP.


ThinkPad T23 2647

Manufacturer - IBM
Series - T Series
Subseries - ThinkPad T23
Machine Type - 2647

1) Remove ALL power. Remove the AC adapter (Charger), and Battery.

2) Battery removed, Battery Compartment facing you.

Look at the right inside edge. There is a small plastic cover inside the Battery Compartment.

Remove the one Philips head screw, then remove the cover.
Backup battery, CMOS battery, or RTC battery. SAME/same.
(Real Time Clock battery)

Also, here is the Service Manual,

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-ibmlenovo

Drop down to the 8th line. (ThinkPad T20. T20 in blue)
Scroll over, and left-click right on - T23

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.

After you click on the file name, (T23), it may take up to 30 seconds, before the first page comes up.

Start on Page 66. Backup Battery is on Page 67.
OR,
In the Bookmarks menu to the left, click on -

1) The + sign to the left of -
ThinkPad T20, T21, T22, and T23 series.

2) The + sign to the left of -
Removing and replacing an FRU.
(Field Replaceable Unit)

3) Left-click right on - 1010 Battery Pack, and 1020 Backup Battery.

Nice to have when you are going to clean that puppy out.
(BUY, and wear an ESD wrist strap. Connect it's alligator clip to a good ground source.
Average price is around $3 to $6)

Also nice to have to upgrade the Processor, and a myriad of other things.

Hello how to reset bios password of ibm thinkpad t23 2647


Hi,

To unlock the bios password on your laptop, you will need to remove the cmos battery on your laptop for some minutes and insert back, the cmos battery is located on the motherboard of your laptop, once the cmos battery is removed from the motherboard for some minutes, the bios password will be reset, and that fix the problem.

Take care.

IBM Thinkpad will not hold date & time.


Replace the backup battery and run BIOS Setup Utility to reset the time and date. This will resolve the issue.

Ibm thinkpad turn on no work


If you're not getting any external display action then that means it's probably a motherboard issue / hardware issue.

First thing you're gonna want to try is reseating the memory and trying to boot the computer with the battery out.

Second, if that doesn't work next thing you can try is removing the cmos battery (with the battery and power adapter out) and letting it sit for 5 minutes with the cmos battery out.

Also, do you get any led lights or any kind of action from the laptop (fans, beeps, etc.)?

Monitor is blank when we turn the computer on.


Maybe not. Find the FN key. It is usually BLUE in color
Then look on TOP row of Computer keyb (or all over) and find CRT/LCD.
Press the FN and that key and your screen should come back. You accidentally sw. it to CRT (outside, external monitor)
