Batteries can develop a dead short and cause a no start. Try starting without the battery. Other things you can try is checking the power supply with an ohm meter,or plug it in and stick it in your mouth, but me personally, I'd use the ohm meter. Also check the memory, a faulty memory chip can cause this. If none of these work, them I'm afraid the problem may be with the power management chip on the motherboard. If the pm chip is malfunctioning, then motherboard replacement is your only option.

My ibm thinkpad laptop stopped working and I thought it was the power supply but I got a new power supply and it still doesn't work.


Please clarify - "doesnt Work".
Does anything happen at all when you press the power button?
Are there lights indicating charging when it's plugged in the wall??
Is the battery in the laptop???

Please use the "continue with this expert" option and reply with a bit more information about your problem.
Thanks!!

IBM ThinkPad R40 No PowerUp


If the the ram is the problem of your system, there should be a power on light on the system. indicating that some of the component of the system is not working correctly. But since you mentioned there is no light, it is the possibility that the problem is the motherboard itself.

Laptop will not turn on


The two most common causes fot this on the IBM machines are the battery and the memory. Start be removing the battery and starting with the power supply only. Then remove the memory and try each chip one at a time in each slot. If these don't work, then I'm afraid a component has failed in the power management system on the motherboard. Failed power management systems are also common with these, but not as common as a battery or memory failure. If it's the power management system, unfortunately, the motherboard will need replaced.

This could be a problem with the battery, try removing the battery and starting on the adapter only. If this doesn't work, then I'm afraid it is going to be a motherboard problem, most likely with the power management system, this is the most common area with this type of problem. You can take it in for diagnostics, but I'm afraid you're going to end up having to replace the motherboard in order to fix the problem.
