Laptop Keeps Restarting Or Shutting Off Randomly?
This is different from a laptop that won't turn on at all — here it powers on, but repeatedly restarts or shuts itself off afterward. The cause can be the charging circuit, the motherboard, or just a software/driver issue — we diagnose the real cause first (from RM100–180+ for the assessment) before quoting a repair, since the final cost depends entirely on what we find.

My laptop always gone to blue screen and keep restart and still blue screen. I was happy because, it takes only 4-5 hours to fix the issue. I had 0 knowledge about laptop/computer. He manage to figure out that my motherboard is corrupted. Thank you. Worth the price

Google Review · Kepong BranchWhat's going on
A real example we received: a customer sent a video showing their laptop turning "on and off like that" repeatedly, and the first question asked was whether this "can even be fixed" — not the price. This is a common pattern for this symptom: people are more worried about whether it's serious than about the cost at the outset.
Common signs to look out for
- Laptop restarts repeatedly without any user command
- Shuts off suddenly during use, then powers back on by itself
- Stuck in a boot loop at the logo screen
- Shuts off especially during heavy tasks (gaming, video editing)
What usually causes it
- Overheating — the system shuts down to protect itself
- Faulty or unstable RAM
- Corrupted or incompatible operating system/driver
- Charging circuit or motherboard not delivering stable power
- A weakening battery causing an unstable power supply
How we diagnose this
Stress test
We run the laptop under load to see whether restarts happen due to heat or another cause.
Temperature & RAM check
Thermal readings and RAM tests are run to catch the most common hardware causes.
Power circuit & motherboard check
If the basic hardware checks out, we inspect the charging circuit and motherboard for an unstable power supply.
Software/OS check
If the hardware is confirmed healthy, we check system logs and drivers for a software-based cause before quoting a final price.
