Your laptop’s power button is pressed. Yet nothing occurs.
There are few technology snafus more aggravating than when your laptop refuses to switch on. You don’t have to accept the fact that your computer has died prematurely. We’ll teach you how to figure out what’s wrong and how to repair it.
A defective power supply, failing hardware, or a malfunctioning screen might be at blame if your laptop won’t turn on . In many circumstances, you may be able to repair the issue by buying new components or changing the setup of your laptop.
However, if your laptop is older and the problem is a costly hardware issue, now could be the ideal time to upgrade.
Make sure the power supply and batteries are in good working order.
Start by inspecting the power supply if your HP laptop won’t turn on even when it’s plugged in. You might have a variety of problems with the power supply.
For instance, the issue might be as easy as using the incorrect charging cable, resulting in insufficient voltage, or it could be that the power supply has failed .
1. Remove your laptop battery entirely to see whether the power source is the problem.
2. Next, connect your laptop to a working outlet.
3. Check that the outlet is working correctly by plugging in another device; if it works, the problem isn’t with the outlet.
4. If you can turn on your laptop without the battery attached, the problem is with your battery, not with the power source.
5. You’ll have to purchase a new one, but you can get by with only using AC power in the interim.
6. It’s acceptable to use your laptop without the battery fitted; it simply means you’ll have to keep it plugged in all the time.
CMOS Battery
Another option is to replace the CMOS battery in the motherboard, which saves the BIOS settings. It is particularly true if you’re using an older laptop that’s been turned off often or has had the primary battery removed. The cost of replacing a CMOS battery is relatively low.
Make sure that all of the wires are correctly attached. Although it may seem easy and apparent, most problems with a laptop that won’t switch on are caused by a power supply problem. Your computer isn’t receiving the electricity it needs because of a loose or disconnected power cord.

Identify screen problems(most probable reason that’s why your laptop won’t turn on)
If your power supply is operational, you must proceed to the next step in the troubleshooting process.
1. Disconnect any non-essential external display devices, such as projectors and monitors, to ensure that they aren’t interfering with your laptop’s starting operations.
2. If the power button is illuminated and you can hear fans or sounds, but no picture is shown, switch down the lights and check to see if a faint image is projected.
3. If you see a dim picture after turning off the lights, the screen’s inverter has failed, and you’ll need to replace it [4].
4. Your brightness button might also be broken.
If your laptop turns on, but no picture appears, Because may damage the LCD screen. It is not difficult to repair a damaged screen; for instructions, see our post here. However, if your laptop is an older model, replacing the complete machine may be more cost-effective.
Turn off all of your laptop’s devices.
If you left a memory card, DVD, or USB drive on your laptop, which is why it won’t turn on.
The BIOS may be attempting to boot from a removable storage device, causing it to get “stuck.” Remove any USB drives and other external devices before trying to restart your computer.
Make use of a rescue disc.
A rescue disc enables you to boot your computer and repair any problems with the Windows operating system [5]. If a virus causes your computer troubles, the rescue disc will detect it using scanning tools and allow you to eradicate it.
Switch to safe mode.
If your HP laptop refuses to come on, you may be able to get it to operate in safe mode [6]. Safe mode enables you to remove any new apps or drivers that may be causing problems with your laptop. It also allows you to establish a new user account if your existing one has been compromised.
Examine your hardware The last stage in diagnosing power problems is to examine your hardware. It’s possible that new hardware, such as a new RAM kit, is the source of your boot problems. Remove and reinstall your new hardware before attempting to boot.
Unfortunately, your laptop’s hardware, such as its hard disk, might fail at any moment, and there is no straightforward cure. If you hear a clicking noise or the disk spins up and then shuts down, it’s an indication that your hard drive has failed [7]. In most circumstances, this signifies that your hard drive will need to be replaced.
Having an external hard drive handy to back up any data you may need is a good idea in situations like these.
Replace, repair, or diagnose
At first, figuring out the answer to the query “Why won’t my laptop come on?” may seem daunting. Laptops make our lives easier by allowing us to access mobile computing solutions that suit our needs.
However, if you use a laptop for work, school, and everyday multitasking, any big problem might derail your productivity.
Don’t get too worked up if your laptop won’t switch on. It’s most likely a problem with the power source, which you can investigate and rectify. Even if the situation is more complicated, there are still cost-effective techniques to test and analyze it.
If nothing else works, a new desktop computer might be the solution to your IT problems.
