Product: HP probook 4540s
Operating System: Microsoft Windows 10 (64-bit)
Hp probook 4540s - When i plug in the charger laptop start straight without pressing power button. But the display does not on. Power button light, charging LED & the power on front LED gets on and the fan spin too. Power drops or lights go off for a second (Do not no whether it restart or no) and on again. This happens continuously. I tried to fix this by Removing K/B, touchpad and removing battery & holding power button for 30 secs while unplugging charger. Cleaned the RAMs and then even replaced them. But nothing went right for me. Can any one help me regarding this?
