    I have the same problem. When I plug in the power cord into the yellow thing in the back it does not connect. I think it has to be a bad connector - not the motherboad. Is it easy to replace the yellow connector? Please help

I've run into this many times with IBM machines. The power management chip on the motherboard has failed. Unfortunately, you will have to replace the motherboard in order to fix the problem.

Ibm thinkpad T43 lap is not charging when connected with ac power supply .Can u help me


Whenyou connect the power adapter into the laptop, does the power LED light up? Ifnot then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a dry solderjoint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

T43 LAPTOP NOT TURNING ON. EVENTHOUGH THE BATTERY IS OK.WHAT COULD BE THE REASON? KEYBOARD LOSE CONTACT OR ANY FAILURE OF COMPONENT


1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad
.
6. The motherboard could be defective & needs to be replaced.

Ibm thinkpad t43 wont boot


Remove the battery, and unplug it from the wall. Leave it for 30 seconds and then try turning it on with just the power plugged in. So without the battery. Best of luck, Ravi Shanghavi, Ottawa

IBM T43 Screen Turns OFF After Removing Charger Cable


Sounds like a bad battery to me. If you have a DC voltmeter you can check the battery.

No power


Check and verify the AC adapter is working.
If it is then you can try removing the battery with the adapter connected try to boot the laptop.
If it boots, reinstall the battery and check to see if it is charging.
Hope this helps.
Good luck.

Laptop ibm t43 does't turn on if it's not plugged in


This generally indicates that you have a short in the battery, or that one of the fail safes in the battery has kicked in. A new battery will correct the issue.
