U can push and hold the ram memory (use a single stick first) while pressing the power on button. If this method is not working, maybe the motherboard has defected.

Try checking the charger output 19v. If theres 19v, maybe the socket itself has loose.

Hello, these capacitors at the main 19v line. They are usually 25v , 10uf rated. As they are in parallel mode with others, you can leave it without replacement. But if you want to replace it, u need to reconfirm the value based on the schematic diagram.

No need jumper. Just release it from motherboard.

I have the same laptop, mate. . Exactly same. . The problem is the LCD is just blinking, mate. . And the power button is blinking as well like in sleep mode. . Any suggestion, mate?

You can try with different ram stick (1 stick) and different charger. If you dont have it, just bring and try at nearest repair shop.

Search 'pasha it solution' on google maps. If it is oversea, we suggest you to send your laptop inside your country.
