And if I press it 2 time the first it blink and then the light is ON for 10 second but no display and the light gets off again
If a power refresh or reseating the RAM doesn’t work , then there is a motherboard problem that would have to found.
Try to locate the motherboard schematics, by searching online for (insert motherboard’s “board number”) schematic, to hopefully find the schematics so that the motherboard’s power circuits can be tested
Disconnect power supply, take out battery and press power button for 15 seconds to discharge any power on the motherboard.
Take out the coin shaped CMOS battery (bottom right in photo shown above) for about 30 seconds. Put back in clip.
Reassemble laptop but do not reinsert main battery.
Try turning on the laptop with just the charger plugged in. Does it boot up?
If yes the charger is good.
If no then the charger may be defective. If possible test with another charger of similar specifications.
If good with charger unplug charger put battery back in. Turn it on. Does it boot up?
If yes you are good to go.
If no then the battery probably is defective.
