My Acer Laptop keeps on turning itself off improperly.. without an unknown reason
It is about 5 months

At first we thought it is caused by some virus..
so we have it reformatted.
New OS.. No files

Still it SHUTS DOWN IMPROPERLY.

So, we asked somebody to open it..
Then he said, It might be because of overheating..

Then he operated it with a cooler.
Still, it turns off improperly.

Next he said it is because of the battery.
He removed the battery..
It was operated with its adapter.
Again, It turns off improperly

What may be its possible problem T____T ?
What can I do with it?
Help please.

Since the OS was already reinstalled and the battery removed (see ), the behaviour is most consistent with a hardware or power-delivery fault rather than malware. and are correct that a depot repair may be needed, but a few focused checks can narrow the cause before sending it away.

Quick, non‑destructive checks to try first:

  • Check system logs (Windows Event Viewer for Kernel‑Power events or Linux journal/syslog) and note exact timestamps when the shutdown happens. Matching a log entry to the time of the cut makes diagnosis much easier for a technician.
  • Rule out RAM and storage: run MemTest86 (from USB) and a SMART test for the drive. Intermittent hardware errors often produce abrupt power loss.
  • Verify power delivery: test with a known‑good compatible AC adapter, wiggle the DC jack while powered, and watch for immediate shutdowns (this isolates a loose jack or failing adapter).
  • Confirm cooling/fan behavior: check that fans spin at boot, watch temperatures in BIOS/UEFI or with a monitoring utility, and clear vents with compressed air. A failed fan or detached heatsink can cause sudden protective shutdowns.

If comfortable opening the case and the laptop is out of warranty, reseat RAM and drive connectors, inspect the DC jack and motherboard for loose components or bulging capacitors, and check the heatsink/fan assembly. Do not attempt soldering or major repairs if the unit is under warranty.

If these checks do not reproduce or explain the shutdown, document the exact conditions (idle vs load, plugged vs battery, any movement) and pursue professional service or RMA. Back up important data first. The symptoms described — abrupt power loss with software already ruled out — commonly trace to the DC jack, power circuitry on the motherboard, or a failing cooling/fan assembly, and a repair shop will be able to confirm and quote.

This is likely a hardware problem - most likely it has some overheating component (CPU, RAM, etc). You need to send it into the repair depot for warranty service.

Take it to the repair shop.

Hello,

My first guess would be it is overheating. Check the vents and make sure that there is some sort of air flow out at least one port. Often people will sit their laptop on something that can block the incomming air flow and the system will shutdown rather than burn out the processor. I also have to agree with taking it in for hardware/warranty work.
