Product: Probook 4540s core i5
Operating System: Microsoft Windows 10 (64-bit)
Hi,
I'm using Probook 4540s with dedicated graphics card from 2013. From 2013 to 2017 I didn't find any problem without keyboard and battery damage issue.I replaced my keyboard and battery once about 1 year ago.
Day by day battery backup was reducing and before 3 days ago I found "Battery not detected" issue.
With that situation my laptop was running with charger adapter [using official HP charging adapter].
But around 15 mins later my laptop was shutted down.Then I tried to restart it again pressing power button. The cooler fan was producing loud sound with no display on or no speaker sound. Then it was shutted down again within 2 sec. I reconnected charging adapter and tried again. But nothing happened on that time. No cooler fan sound, no sound from speaker, no spinning sound from hard disk. Just the charging LED is beeping now with white color.LED is blinking continuously.
I tried to do hard resetting. Nothing happens.

My laptop was running with latest version of BIOS.


What should I do now anand what's the problem?

TIA
