Lenovo Thinkpad X240 Troubleshooting

This troubleshooting page will help you diagnose problems with the Lenovo Thinkpad X240.

Faulty Touchpad ¶ 

The touchpad is sometimes unresponsive.

Touchpad maybe dirty ¶ 

Once the touchpad gets dirty it may seem less responsive. The touchpad may only be covered and can easily be cleaned off to fix this issue.

Short Battery Life ¶ 

The battery life is short so the laptop will power off soon without a charge.

Faulty Power Adapter ¶ 

Make sure the power adapter is plugged in and that the light is on. If the light is not on while the power adapter is plugged in, the power adapter is faulty.

Faulty Battery ¶ 

Plug in power adapter and make sure the light on the power adapter is on. If the computer only turns on with the power adapter connected to it regardless of how long you charged it, then the battery is faulty and you should replace the battery.

Aged Battery ¶ 

The battery has a certain amount of power it can store and over time this amount can decrease. The easiest fix to this problem would be to replace the battery with a new one.

CP moving slowly ¶ 

The CP will often take more time to do simple task.

Not Enough RAM ¶ 

When there are too many things such as documents and programs, the laptop might work slower than the usual. You will probably need to delete some old files that are no longer in use.

Frequent Overheating ¶ 

The laptop will overheat and possibly shut off or freeze.

Fan overheats ¶ 

If fan is getting too hot or not working the fan may possibly be overworking itself and is not strong enough for the laptop. In order to fix this a new fan must be installed.

Dirty fan ¶ 

Once the fan gets dirty it may seem less responsive. A quick clean will speed up the fan making it work faster.

Hot area ¶ 

If you are using your laptop outside, the sun might affect the laptop’s fan. It will probably make the laptop hotter and cause the fan to work harder. To fix this, taking the laptop to a cooler area should help.
