Black screen, blinking charger socket light, power and caps lock lights are constantly on

Hi there,

 

My laptop doesn't turn on - black screen and exhibits some strange features.

 

The power button and caps lock are on, but the light of the charger socket blinks. No noise from the fan or the HD. No beeping sound at all. I tried to turn it off, but it didn't respond - the light of the power button is on.

 

It’s not about battery. At the begging the power button was flashing, as if there was no charge. When the AC was connected and the battery was obviously recharged, the power button was constantly on.

 

No matter what I do, however, the charger socket light is constantly blinking.

 

I removed the battery, took out and put the RAM memo in a different slot. Removed the HD and then again connected it.

I tried hard restart - without battery and AC power, I pushed the power button for 30 sec. Then I tried to turn it on with battery and AC, nothing happened.

 

I hope someone has some advice.

 

Thanks a lot.
