Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.
remove the battery and power cord then remove the battery on the mother board, hold down the power button for 60 seconds to drain the capacitors, if that doesn't work it's the motherboard that should be replaced.
All rechargeable batteries have a limited life, and as they age their charge capacity reduces over time and you get shorter and shorter time between charges.
Recharage batteries have a finite number of charge and discharge cycles and batteries over 2 years old are considered nearly worn out. Worn out batteries won't charge up at all.
when any computer posts/boots up.
it goes through a sequence of initialising things before booting.
i,ve been repairing computers for around 12-15 years.
1st i,d try removing the ram ( memory ) usually underneath the laptop, behind a screw cover. Or ocassionally under the keyboard.
if 2 sticks of ram are installed, remove the battery. and 1 stick of Ram. put battery on and try to boot. if no joy with that try the other stick of ram. and replace battery-Re-boot.
If this works you have 1 stick of faulty ram or faulty ram slot on motherboard. Failing this. I suspect that the CPU has overheated, and therefore a replacement Processor should solve the problem.
