[BrokenK]

Computer powers on, then goes into "Preparing Automatic Repair" dot dot dots go round and round clockwise than stops. Screen freezes, screen goes black, reboots, repeats.

F1,F2,F9,F10 work, Bios won't roll  back gets stuck there !

F11 - accepts command and trys to start, but screen is always black and white. Never getting the blue repair windows.

- removed ram , CD-ROM, No loose connections, never been dropped.
- performed all the tests, short and long, one took 7 hrs.

- shut off the power, unplugged all power sources except fro the CR2032, its ok. But the 2016, 9 year old windows 10 laptop simply will not boot O/S or Repair options.

Performing a hard reset clears all information in the computer's memory and may restore functionality.

• Steps for Hard Reset:
  1. Turn off the computer.

  3. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
  4. Unplug the AC adapter from the computer.

2. Update BIOS and Drivers

Ensure BIOS and drivers are up-to-date to fix compatibility issues.

• Steps for BIOS and Driver Update:

  2. Navigate to the update section and follow the instructions for updating BIOS.
  3. Use the HP Support Assistant to check for and install the latest drivers.

3. Boot to Safe Mode

Booting in safe mode forces the computer to load a limited version of Windows which only contains essential files.

  2. Turn the computer on and immediately press F8 repeatedly until the Advanced Boot Options menu appears.
  3. Select Safe Mode using the arrow keys and press Enter.
