Laptop shuts down 2 seconds after turning on?

[jmastera]

Sometimes my laptop does not even turn on. When I hold down the power button without a power source, then plug it in and try turning it on it will start but two seconds later it shuts off. Anyone have a good idea of what might cause this?

Hi,

It could be the battery or the motherboard of your laptop. Remove the battery then plug in just the charger and turn it on see if it will replicate the problem. If it turns on that means it's the battery. Also check if it's your HDD to test if it's your HDD.

- Remove the HDD off the laptop then turn it on.
- You'll get an error message saying boot device is missing or something and that's normal
- See if it will turn off again without the HDD, if it turns off again that means it's the motherboard.
