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?
