Product: HP probook 4540s
Operating System: Microsoft Windows 8.1 (64-bit)

i have a probook 4540s which keeps restarting even after i shutdown or hibernate. i have updated the BIOS, i have tried HP pc hardware diagnostics UEFI upon startup, i have tried hard reset, i have load another OS but every time i put the battery into the laptop, it turns on on its own. one thing i've noticed is that the caps lock light stays on after i shutdown, before it restart. any help would be appreciated. thanks
