Computer Won't Turn On?
Three common scenarios — and what each one usually means.
"Won't turn on" can actually mean a few different things, and each points to a different cause. Before assuming the worst, it helps to know which of these three situations matches yours:
Scenario 1: No power at all — no lights, no sound, nothing
What it usually means: a power issue — the charger, the charging port, a drained or failed battery, or (less often) a deeper hardware fault.
What to check first: Is the charger's LED lit when plugged in? Does the laptop show any charging indicator at all? If there's genuinely zero sign of life even when plugged directly into a wall outlet, this is very likely charger, battery, or charging port related.
How we fix it: We test the charger, battery, and charging port separately to isolate which one has failed — see our Battery Replacement and Charging Port Repair pages for those specific fixes.
Scenario 2: It powers on (fans spin, lights come on) — but the screen stays black
What it usually means: the device itself is working, but something's preventing a display — could be the screen itself, the graphics hardware, or a connection issue between them.
What to check first: Connect to an external monitor if possible. If the external monitor shows an image, the built-in screen itself is the problem, not the rest of the computer.
How we fix it: We isolate whether it's the screen, the display cable, or the graphics hardware — see our Screen Replacement page if it turns out to be the display itself.
Scenario 3: It powers on and starts booting, but won't finish loading Windows or macOS
What it usually means: a software or operating-system-level problem — a corrupted OS, a failing drive, or a Windows/macOS update that didn't complete properly.
What to check first: Does it get stuck on a logo screen, show an error message, or loop back to a black screen repeatedly? Any error code shown is useful information.
How we fix it: Depends on the cause — could be a System Installation (fresh OS setup), a Hard Drive Replacement if the drive has failed, or Data Recovery first if the drive is failing and data isn't backed up. See our Error Messages page for a specific code or symbol.

Won't turn on — common questions
Could a faulty power outlet be the actual cause?
Does a computer that won't turn on always mean data loss?
My laptop shows no signs of life at all — is it definitely the battery?
The fans are spinning but I see nothing on screen — is this serious?
Will I lose my data if my computer won't turn on?
Should I keep trying to turn it on myself, or bring it in?
