Lenovo ThinkPad A285 Overheating

The more demanding the tasks your device handles, the more heat it produces. A rise in temperature doesn’t necessarily mean your device is overheating or at risk. There are a few simple ways to check whether the heat levels are within a safe range.

• Open Task Manager: Press Ctrl+Shift+Esc.
• Click on the Processes tab.
• Click on the CPU column to sort processes from highest to lowest CPU usage.
• Identify and end processes that have a high usage of CPU. Click "End task".
• Continue until CPU usage returns to normal levels.

A lack of air movement can also occur when the fan inside isn’t working properly. Fan failure could be caused by dust blockage or a broken fan.

Listen to see if the fan is working correctly. If the fan is making a normal sound, showing signs of proper function. The fan should not be the problem. If the fan is making any clicking, breaking, or grinding sounds. You may want to replace the fan. Please refer to the Fan Replacement guide if you need to replace the fan
