Can you take your battery out and turn on just with the adapter plugged in? Works? The adapter is ok. Windows is not recognizing your battery so it can not charge it. Remove the power again, put the battery back in again and notice if it is loose or not a good fit.
Ask the service center to test your system with a different battery as they do wear out! Samr thing with a different battery, the charging curcuit and connection from the battery system to the motherboard may have gone out or received damage from a short curcuit or power problem... in this case they may be correct about the motherboard.
If the system is still under grarantee, let them do the work... if not, continue to use the machine without a battery, only connected to wall power... till something else goes wrong. The repair may be more expensive than a newer model.
I think it would be better to isolate the problem of the machine what could be the cause of the problem if its software or hardware. If its a hardware we have to check what hardware is causing the problem. If its software mostlikely it can be resolved by reinstalling OS(windows).
Try to do this.
1. Remove the battery and Unplugged the AC power
2. Press and Hold the power button for 1 minute without the battery and AC power.
3. Put it all back.
4. Check if the machine would turn on.
If the machine still not turning on most likely its a hardware. It could be the Power Port at the side of the machine, the Motherboard, Memory, LCD or the Hard Drive.
If the machine turns on or give a display kindly check what message it gives you because it could be a problem also with the hardware.

If the led on the power supply turns off after connecting it to your laptop, the problem most likely lies with the power supply especially if the machine will run on battery power. This can be tested by
1. Turn the laptop off.
2. Remove the battery and power supply plug.
3. Press and hold the power button for at least 15 seconds to reset the laptop.
4. Replace the power supply plug into the laptop without replacing the battery.
5. If the computer will not start and there are no lights turning on on the laptop the power supply is bad.
6. Replace the battery and attempt to start the machine both with and without the power supply plugged in.
This could be a problem with the motherboard. Try to do troubleshooting first. If you will be getting the same thing then you need to have the motherboard replaced. Take out the battery then unplugged the power adapter from your computer. Press and hold the pwer button for 30secs without the battery and the adapter unplugged to the computer. Put everything back in then restart the computer. Call our techsupport at 18774536686 then press option 2 if same thing happen.
It does not need the battery to turn on if you have the power brick. Most bricks have a green light to indicate they are working. You should also see some indication on the computer that it is getting power.
Not turning on could be many problems including a bad power brick, bad on/off switch and many more items.
I don't get paid for advice so if this answers your problem, I would appreciate 4 thumbs.
Firstly insert the battery. When you plug the PSU into the machine
does a charging light turn on? If not then check the fuse in the mains plug as
it may have blown. If the fuse is OK then you may have a defective PSU,
although the motherboard could also be defective. Try a new PSU to determine if
which component is faulty.
Now remove the battery and insert the PSU. Will the machine
turn on or do any power lights illuminate? If power lights illuminate and the
machine will not turn on then I would suggest the motherboard is at fault. If
the machine turns on briefly the turns off before displaying the splash screen
then I would suggest the RAM, CPU or motherboard is at fault.
If the unit works without the battery installed then it is
probably a battery problem, although it is possible the charging circuit n the
motherboard is fried.
Hope this helps,
Hi, The Thinkpad T42 doesn't have a reset button on it like the older IBM's used to.
There could be a problem with the battery. With the machine turned off remove AC power and then the battery. Plug in AC power again and see if the laptop will boot without the battery. If it boots let it load up as normal and then shut it down again, reinsert the battery and try to boot it up. If it boots fine, if not then there is a problem with the battery.
