Operating System: Microsoft Windows 10 (64-bit)

Hi, the battery is totally drained, has been unused for years.

I tried to power the laptop up with power supply, 19,5v 65W  with no success.

The white light on the power button is on for 6 seconds and than a very short, maybe 0,2 seconds off and 6 new seconds with light on. Right before the power light turns off, there is a short flash of orange light from the charging light.

I have tried:

Different power supply

Disconnected battery

Holding the power button for 30 seconds

Removing hard drive

Removing RAM

Removing keyboard

Different hard drive

Update 03/22/2020

Removed cmos battery

Holding Windows+B+ Power for 12 sec.

Removed wifi card

Removed card for connecting dvd player (mini sata card)

disconnected and checked all cables/plug on the mainboard

 

 

There is no sign to reaction when pushing the power button, no sound, no fan.

The lights is acting in the same pattern always.
