Laptop only works when plugged in

My HP Compaq NX9105 will only work while plugged into the mains. If you pull the plug while the laptop is running, it goes dead (much like a PC would if you did the same to it). Pretty certain the battery is fine so what needs fixing/replacing?

    So how do I go about fixing it?

    I have a HP DV1321us. It will charge the battery and run on ac supply but when I unplug it, it will die after about 3 seconds. The battery is fully charged but it just is not getting power to the motherboard for some reason. Any help would be appreciated. Thanks,

If the battery is good, then you have a bad motherboard connector.

    Usually replacing the battery it is fixing the problem. In your case you said that the battery is ok, so the problem is in the board or the connectors, to fix that the laptop must be serviced.
    But you can try before with another battery from similar laptop or a new one and see what happen first.

Hp compaq laptop no power


you 1st need to confirm that your mains adapter is working properly, does the charging light on your laptop come on when plugged in? if it does, then good.

you should be able to cancel hibernate mode by holding the power button for about 10-15 secs

hopefully this will then allow you to power up as normal,

I don't like Hibernate mode myself as I have had previous problems with it and I tend to disable my laptop from hibernating.

if the charging led does not light when you plug in your laptop the it is possible that you have a faulty Power adapter or power controller circuit.

hope this helps
