Is your laptop not booting up? Of course, it might be a serious issue or sometimes it could be something that you can usually fix yourself instead of rushing to a laptop service provider. Check these signs and try fixing a laptop that won’t boot.
Is your power supply alright?
Sometimes your laptop won’t boot up as it may have a mismanaged power supply from the Power/AC Adapter or due to a fuse in the plug.
Remove the battery and see if it works on the main charge. Make sure the charger is the right one for your laptop. You might have brought a ‘universal’ power charger once your original charger fails and it might not be suitable for your laptop. Try changing the fuse or check it by using a spare power cable in the plug. Check the cord of the charger if it’s worn out, if you can see the colour wires inside the cord, replace it.
Is your screen actually working?
Disconnect all external displays like projectors and monitors. When the power LEDs lights up and the hard disk or fans can be heard humming, then dim the light in the room to see if you can see a faint display of the screen. In fact, your laptop is booting and there is a problem with the screen where the inverter might have failed or the LCD panel is faulty and you need to replace them.
Is there any USB drive or memory card connected?
Remove any external USB drives, memory cards or DVDs. Usually, the BIOS will try to remove storage devices before booting, but sometimes it may not work.
Did you use a rescue disk?
Are you encountering error messages, or does Window freeze before logging in, then use a Windows DVD if you have one, or download the rescue disk image from other sources and burn it into CD/DVD or extract it to a USB drive? Boot from this and try to fix the problem.
Did you try booting in Safe mode?
Sometimes you can boot in Safe mode. Press F8 when the laptop is starting and choose to boot in Safe mode. Here you will be able to make any changes, uninstall recently installed programmes, uninstall recently updated drivers or create a new user, if the previous one is corrupted.
Do you have a faulty or incompatible hardware?
If recently you have installed a new hardware, that might be causing problems in booting up. Remove and try booting again. Sometimes your motherboard will have some postcodes shown in its LED readout, know what those codes means using a manual or searching online. Remove all unnecessary hardware except the basic ones and try booting again.
Is there a hard disk failure?
Sometimes your hard disk might be at fault. Try inserting Windows installation or recovery media and run Start-up repair operation. If your hard disk makes a regular clicking or spinning sound with powering down over and over, it might be broken and needs to be replaced.
