I was using my HP Probook 4540s when the screen turned black so I shut down the computer. When I tried to boot the computer back on the computer would flash the HP logo then the screen would go black. This cycle repeats itself forever every 5 seconds the logo is flashed back on the screen. The computer was running Windows 10 before this problem started occurring. I ran tests in Bios and the results were:

Processor Check: PASSED Memory Test: PASSED Hard Disk SMART Check: PASSED Hard Disk Short DST: PASSED Hard Disk Optimized DST: PASSED Hard Disk Long DST: PASSED Battery Test: NOT INSTALLED WLAN Module Check: PASSED PCI Device Check: PASSED Video Memoery Check: PASSED

When I used to boot the computer in the past I would get an internal battery warning. Could this problem be a result of the battery? How can I solve this problem?

  • See if the NUM lock and CAPS lock leds are blinking, it could mean a problem has been detected. – simlev May 10 '17 at 13:16

  • Try using Windows Installation disk to boot, and see if you can get to safe mode. More info here : groovypost.com/howto/create-windows-10-bootable-usb-flash-drive – Vylix May 10 '17 at 13:38
