I have been using IBM thinkpads for a while now and have never faced such problem. I have an IBM thinkpad which is installed with Windows Xp on it. Last night the thinkpad shut itself down while working and now it does not turn on. All the LEDS on the thinkpad glow when power button is pressed. Can anybody here explain me What is the problem with dead IBM ThinkPads? Any help is highly appreciated.
It is possible that the battery of the laptop is out of charge due to which the laptop is not booting. Sometimes the battery of the laptop does not get charged when connected to the AC adapter. If such a situation occurs then the system will only work till there is enough charge in the battery. Connect the laptop to the AC adapter and let the battery charge for about 3 to 4 hours. Disconnect it from the AC adapter and check if the laptop is booting.
If the system is not able to access the RAM chips then it will not be able to start. The files which are required for the operating system to boot are first loaded in the system RAM and are then executed from there. Hence if the system RAM is inaccessible then the system will not boot. Open the laptop and remove the RAM chips from its respective slots and clean the connecting terminals. Replace the RAM chip back in its slot and boot the system. If there are multiple RAM chips then try and boot the system using single RAM chip at a time. If for any RAM chip if the system does not boot then discard the RAM chip as it may be faulty.
As the laptop was working when it shut itself down, I suspect that there is some heating issue related to it. If the internal components of the laptop gets heated up beyond the threshold level then the system will shut itself down to prevent damage to the internal components. In this situation I would suggest that you take the thinkpad to the nearest service center and get it checked. If there is any hardware failure associated to the problem, it will be solved for free if the laptop is under warranty. Otherwise some charges will be levied.
The motherboard of the computer is responsible for all the functions which are carried out by the computer. Hence for proper working of computer, the motherboard should work properly. If the motherboard is not working properly, then the system will give problems which are similar to the one which you are facing. Get the motherboard of the laptop checked and see if it is faulty or not. If the motherboard is faulty then you will have to get the motherboard replaced.
Most of the laptops face the problem with residual charge storage. Residual charge gets stored near the RAM chips and other components on the motherboard. If the residual charge stored on the laptop reaches the threshold level then the system will not be able to access all the components and hence will not boot. To bring the laptop back to working state, you will have to clear the residual charge of the laptop. To clear the residual charge from the laptop, shut down the laptop and remove the battery. Press and hold the power button for about 30 seconds. Replace the battery and check if the laptop is booting or not.
According to me the power bank on the laptop must not be working properly due to which the system is not able to power up. Power bank situated on the motherboard of the laptop must not be able to provide correct voltage levels to all the components which are connected to the computer. Hence when you are pressing the power button the system is not able to provide right amount of voltage and hence it is not powering up. Ge the powerbank on the motherboard checked and if it is faulty, get it replaced. Replacing the powerbank will solve the problem.
