Laptop not starting up

[AT01]

Today morning when I tried switching on my laptop,it didn't switch on,so I tried to plug in AC adapter and then tried,but it still didn't switch on(and there where no LED lights).So then I removed the battery and plugged in the AC adapter while the lid was closed,and the charging LED lit up,but whenever I open the lid,the LED stops shining and nothing works again.So in order to make the LED light shine again I have to replug the adapter while the lid is closed.

Hi @AT01,

I'd like to help!

Step 1: Remove discs and devices

Before troubleshooting startup issues, remove or disconnect all discs and devices from the computer.

1. Turn off the computer.

2. Remove any discs and USB devices.

3. Remove memory cards from the card reader slot.

4. Disconnect all non-essential devices such as printers, scanners, external hard drives.

5. Leave only the mouse, keyboard, and monitor connected.

After you have removed all discs and devices, turn on the computer.

• If the computer starts, reconnect devices one at a time, to determine which disc or device is causing the problem. If the issue is solved, troubleshooting is complete.

• If the computer still does not start and exhibits the same problem, press and hold the Power button to turn off the computer. Do not connect anything, and then continue troubleshooting.

Step 2: Perform a hard reset

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a Hard Reset.

After you have completed these steps, if the computer startup issue is resolved, go to HP PCs - Updating Drivers and Software with Windows Update (Windows 10, 8, 7), and then go to HP PCs - Using HP Support Assistant (Windows) to update all device drivers.

Use one of the following sets of steps to hard reset your computer:

Step 3: Run hardware diagnostic tests

Make sure the issue is not hardware related by performing diagnostic tests.

1. In Windows, search for and open the HP PC Hardware Diagnostics for Windows app.

   If the app is not installed on your computer, download the latest version from the HP Hardware Diagnostics website.

2. On the main menu, click System Tests.

3. Click the System Fast Test tab.

4. Click Run once.

   While the test is running, the time remaining and test result for each component displays on the screen.

5. If a component fails a test, write down the failure ID (24-digit code) and

   If no system component failed, continue with these steps.

6. On the HP PC Hardware Diagnostic app, click System Test, and then click System Extensive Test. The Extensive Test might take several hours to complete.

   • If an issue is not found, continue to the next step.

   • If a component fails a test, write down the failure ID (24-digit code) 

Step 4: Refresh or reset your PC

Use Microsoft's Refresh your PC feature to reinstall Windows without affecting your personal files, apps, or many of your settings.

1. On the Choose an option screen, click Troubleshoot.

   If your computer does not open to a blue Choose an option screen, skip this step and go to HP Notebook PCs – Advanced Startup Troubleshooting (Windows 10, 😎 or HP Desktop PCs – Advanced Startup Troubleshooting (Windows 10, 😎 for further troubleshooting options.

   

2. Click Refresh your PC.

   

3. Click Next.

   

4. Wait for Windows to open, and then follow any on-screen instructions.

   • If the computer starts and opens Windows, you are done.

   • If the computer does not start and opens to the Choose an option screen, go to the next instruction.

5. On the Choose an option screen, click Troubleshoot.

6. Select Reset your PC.

   

7. Click Next.

   

8. Select the quick option to remove your personal files.

      CAUTION: 

   Your personal files and settings are destroyed by performing this step. Make sure you have backed up all your important files before continuing. Do not continue if you have important files on the hard drive that have not been backed up. You might want to seek a professional data recovery service to restore your files.

9. Wait for Windows to open. Follow any on-screen instructions.

   • If the computer starts and opens Windows, you are done.

   • If the computer does not start and opens to the Choose an option screen, continue to the next step to run Microsoft System Restore
