If your laptop won’t power on, even when it’s plugged in could have a faulty power supply, battery, motherboard, video card or RAM. When troubleshooting a laptop that won’t start, begin with the basics. Ensure the plug to the power cord is plugged into an outlet and to the computer. Check the laptop’s battery and power connector to make sure the connection hasn’t come loose. If it’s still not turning on, it could be a problem with an internal component. However, you are definitely booting your PC if you start with it turned off.
When the computer powers up, it performs a power-on self-test to make sure the minimum hardware required to continue the boot process is functioning quickly. Write down the pattern of beeps you hear and check with the manufacturer of the PC’s motherboard to determine what the beep code means, as each one has a different set of beep patterns. Enter your computer’s BIOS or UEFI firmware setup screen and check its boot order setting, ensuring that it’s set to boot from the correct hard drive. If your laptop won’t power on even when plugged in, it could be caused by faulty power supply, motherboard, RAM, video card, battery, etc. You can ensure the computer power cord is well plugged into an outlet, and follow the 10 ways in this post to fix the “laptop won’t turn on even when plugged in” problem. Once you have done Minecraft so, it is time to check the connecting cables.

Take the motherboard out and put it on a flat insulated surface such as cardboard or wood . Do NOT put your motherboard on an anti-static bag or anything else that could conduct electricity – this can ruin your components. Install your CPU, RAM, and video card if you have one, then hook up your power supply and try to get it to boot by jumping the power switch pins on your board. If it boots up while you have it breadboarded, your case could be making contact with the board somewhere it should not be and shorting it out.

- If your computer came with a graphics card, HP may have installed a plastic cover over the video port attached to the motherboard.
- Try removing your RAM and graphics card, and reinstalling them.
- Both components require an excellent connection for the computer to boot and operate correctly.
- Similar to one of the popular power supply issues, many will neglect to use sufficient force to install their RAM or graphics card.
As far as components are concerned, the most important ones are the power supply unit at the back that supplies power to the system, the motherboard, the processor, the video card, and memory. Push the power button and ensure the monitor is getting power. Make sure the power cord for the monitor is plugged in and the video cable is connected to the correct port on the back of the computer. Verify the computer is actually powered up and running by checking the power lights on the case or listening for the fans and hard drive spinning. If you’ve recently opened the computer and touched any components, static electricity may have caused damage. If you suspect that an internal component is causing the issue, take the computer in for repairs or speak to the manufacturer for warranty and replacement details.
To make sure it is off, hold the power button down for at least five seconds. If not, you can leave it until the battery runs flat then try again. If you are getting a power or charging light, listen and watch for signs of life.
Similar to one of the popular power supply issues, many will neglect to use sufficient force to install their RAM or graphics card. Try removing your RAM and graphics card, and reinstalling them. Both components require an excellent connection for the computer to boot and operate correctly. While you’re at it, try removing the CMOS battery for a minute, and reinstalling it. If your computer came with a graphics card, HP may have installed a plastic cover over the video port attached to the motherboard. Most PCs can use graphics from the graphics card or the motherboard, but not both at the same time. If you remove the plastic cover to connect a monitor , the video will not work unless the graphics card is removed.
Generally you will see a slight change in the screen – perhaps a darker black when the backlight turns on. Or maybe the cooling fan comes on for just a moment and moves some air – check the side or rear vent for movement and listen for sound (sometimes it’s too slight to feel). Usually the hard drive is under the palmrest area to the left or right of your touchpad. Put your ear to it and turn the computer on to see if you hear anything. If the laptop doesn’t work after you’ve replaced the battery AND power brick AND tested the hard drive AND reseated the RAM, then it’s likely a safe bet that the laptop is dead. It may be cheaper to replace the laptop with a used model or to purchase a new one. Check if your motherboard might be shorting out inside the case.
The better solution is to connect an adapter to make the connection. If the monitor proves to work on another PC, the problem lies with the computer itself. Shut the computer down, then power it back up again and take special note of the number and lengths of beeps you hear as the computer begins to boot.
