Quick answer: Most laptops that won’t turn on have one of four problems: the charger, the battery, the charging port or a fault on the motherboard. Try the free checks below first. If it’s still dead, a technician can tell which one it is in a free diagnosis. Updated November 2026.
Did it die after a spill, a drop or a burning smell? Unplug it and stop pressing the power button. Each attempt can spread the damage. Skip the checks below and see laptop water damage repair.
Free Checks to Try First
- Charge it for 30 minutes. A fully drained battery can take a while before the laptop shows any sign of life. Check that the charging light comes on.
- Try another socket and check the charger. Look for a light on the adapter brick, kinks in the cable or bent pins. If you can borrow a matching charger of the right wattage, try it. See power adapter.
- Do a hard reset. Unplug the charger, hold the power button for 30 seconds, then plug back in and try again. On laptops with a removable battery, take the battery out first.
- Check whether it’s the screen, not the laptop. If you hear fans or see keyboard lights, plug into a TV or monitor. If a picture appears there, the laptop is on and the fault is the screen. See laptop screen repair.
- Unplug everything else. Remove USB drives, docks and SD cards, then try again.
What Your Symptoms Point To
Completely dead: no lights, no fans, even on the charger
If a known-good charger doesn’t help, the usual causes are a failed charging port or a power fault on the motherboard. Brand service centres often quote a whole new board for this, but it’s usually one failed chip. See laptop motherboard repair.
Only works when the cable is held at an angle
A loose charging port or a worn charger cable. This is a small solder repair, usually far cheaper than a board repair.
Works on the charger, dies the moment you unplug it
The battery is worn out or has failed. See laptop battery replacement. If the trackpad or case is bulging, stop charging it: that’s a swollen battery.
Lights and fans come on, but no picture anywhere
If an external monitor also shows nothing, it’s usually a memory or graphics fault on the board. Beeps or blinking lights are error codes that help pinpoint it. See POST.
Turns on, then switches off after a few seconds
Common causes are a failing battery, overheating from a blocked cooler, or a short on the board. If it cuts out when warm, see laptop overheating repair.
Starts, but stops at a blue screen asking for a recovery key
The laptop is working; Windows is locked. See BitLocker recovery key.
What It Costs to Fix
| Cause | Typical cost (SGD) | Usual turnaround |

Won’t Turn On: By Brand
Each brand has its own common power faults and error codes:
FAQ
Is my data lost if my laptop won’t turn on?
Usually not. A laptop that won’t power on almost always still has its files on the drive. Battery, charging port and chip-level board repairs don’t touch your data.
Can a dead battery stop a laptop turning on even when plugged in?
Yes. On some laptops a failed battery stops the laptop starting even on the charger. Testing with the battery disconnected shows whether that’s the cause.
Should I go to the brand’s service centre?
If your laptop is still under warranty and the fault isn’t from a spill or drop, yes, since the repair is normally free. Otherwise an independent shop is usually faster and cheaper. See out-of-warranty repair.
