Sometimes, improperly connected external devices can prevent startup. Try removing USB drives, the mouse, and the keyboards, then restart the laptop to see if the issue is resolved. If the Acer laptop can turn on normally, it may be the culprit.

Fix 6. Reinsert CMOS Battery

On the motherboard of a laptop, there is a small circular battery called a CMOS battery. It is conducive to offering power to the BIOS (basic input/output system) to control the laptop’s basic operations. If the CMOS battery is loose, you may run into a startup issue.

So, try to reinstall this battery via these steps:

You may run into CPU overheating or hard drive overheating. In computing, overheating issues are serious since chances are that your PC malfunctions now and then. When your Acer laptop is overheated, it may shut down accidentally or not turn on at all.

So, when your Acer laptop won’t turn on, wait some time until the machine cools down. Then, try to power it on to see if it can boot up.

Besides, make sure the cooling vents on your laptop are not blocked and they are clean & dust-free since dust can accumulate and block airflow, causing your computer to overheat. Clean the machine using a can of compressed air.

Fix 8. Change Thermal Paste

There may be a dried-up thermal paste on the CPU. In this case, nothing can transfer heat from the chip to the heatsink, leading the Acer laptop to get overheated. As a result, the PC shuts down abruptly and cannot turn on for a few hours.

To solve the Acer laptop not turning on issue, change the thermal paste:

Step 1: Open the back case of your laptop.

Step 2: Unplug the power cord and remove the battery.

Step 3: Remove any cables that connect the fan to the motherboard and remove the heatsink to access the CPU.

Step 4: Clean the previously applied thermal paste from the CPU chip and heatsink.

Step 5: Apply the new thermal paste.

Step 6: Assemble all the parts you have removed again and turn on your PC to see if it can start up.
