While it may be scary, there are often straightforward solutions to get your laptop back in working order.
Cause of Laptop Not Turning On
There are a lot of potential causes for a laptop not turning on. These may include a problem with the power adapter, laptop screen, battery, or even a faulty component on the motherboard.
How to Fix it When Your Laptop Won’t Turn On
To resolve an issue with a laptop that won’t turn on, you should work from the most likely causes, which are the easiest to fix, and work your way to the most difficult. Like any electronic, laptops don’t live forever. If your laptop isn’t under warranty anymore and repair fees are steep, it might be cheaper to purchase a new one. If you do buy a new one, see if you can upcycle the old one instead of tossing it into the trash. However, if your laptop’s power light is on, the power supply is probably working. If both the laptop power light and the adapter power light are on, it could indicate a battery problem. First, if you’ve connected to an external monitor, turn up the volume. If that doesn’t work, disconnect the external monitor to see if the desktop appears on the main laptop window. If not, use the brightness function key on your keyboard to increase the brightness. Try plugging a different external monitor into your HDMI or other video output port to check if the problem is just with your laptop’s display. Detach your laptop from the docking station and plug the power adapter directly into the laptop. If your laptop starts, then you need to replace the faulty docking station. You can remove any residual electricity by removing the battery, disconnecting the power adapter, and pressing and holding the power button for 30 seconds. Connect the power adapter again, wait 30 seconds, and then turn on the system. If your laptop starts, turn it off again and reinstall the battery. It’s also a good idea to clean all vents in your laptop case because hair, dust, or other debris can also cause overheating. If this battery is dead, the laptop won’t start. You can replace the CMOS battery yourself if you feel comfortable opening the case. However, most people opt to have it replaced by an experienced technician. Try putting the old component back or sending the new one back to where you bought it for testing and get a working replacement.
