Laptop Won't Turn On
What to do when your laptop or desktop computer won't power on or boot up
Your laptop (or desktop) won't turn on. Before assuming the worst, work through these steps. Most of the time it's something simple like a dead battery, a loose cable, or a stuck power state.
Regardless of whether it's a Mac or Windows machine, start here:
- Check the charger. Is it plugged in on both ends? Is the outlet working? Try a different outlet. Look at the charging indicator light on the laptop (if it has one). If you have a USB-C charger, make sure it's plugged into the correct port — not all USB-C ports charge on every laptop.
- Try a different charger if you have one. Chargers fail more often than you'd think.
- Look for signs of life. Any lights, fan noise, or a brief screen flash when you press power? If yes, the machine is getting power but something else is wrong. If nothing at all, it's a power issue.
- Connect an external display. If the laptop seems to power on (fan spins, lights come on) but the screen stays black, the display or its cable might be the problem. Plug in an external monitor via HDMI or USB-C and see if anything appears.
Frequently Asked Questions
My laptop was working fine yesterday. Why won't it turn on now?▾
The most common cause is a drained battery combined with a charger that isn't delivering power — a loose connection, a damaged cable, or a bad outlet. The second most common cause is a stuck power state, which the hard reset fixes. Actual hardware failure with no warning is rare but does happen, especially with older machines.
What's the difference between a hard reset and a factory reset?▾
A hard reset (holding the power button) just forces the computer to power cycle. It doesn't erase anything — your files, apps, and settings are all untouched. A factory reset wipes the machine back to its original state. The hard reset described here is completely safe to do.
My laptop turns on but the screen is completely black. Is the screen broken?▾
Not necessarily. Connect an external monitor first. If the external display works, the issue is likely the laptop's display, its cable, or the backlight — not the whole machine. If neither display works, the problem is with the GPU or motherboard.
Should I try replacing the battery myself?▾
On most modern laptops, the battery is glued or clipped inside and replacing it yourself can void the warranty. If your machine is out of warranty and you're comfortable with small tools, battery replacements for popular models are well-documented online (iFixit is a good resource). Otherwise, let a repair shop handle it.
The charging light comes on but the laptop still won't start. What does that mean?▾
The charger is working and the battery is receiving power, which rules out a power delivery issue. The problem is likely with the boot process itself — a corrupted OS, failed storage drive, or a stuck component. Try the hard reset first. If that doesn't help, try booting into recovery or safe mode.
