Hp elitebook 8440p power connector is broken

The_Dude8 · 01-17-2013, 02:52 AM

Has anyone taking apart a HP elitebook 8440P laptop before? thinking the power connector is broken, since it doesn't charge the battery anymore. I know the ac adapter works since i use the same adapter to charge a different hp.

How easy is it to fix a loose power connector? Anyone done it before on their old laptop?

Thanks

he does a vaio power jack fix here, his preferred method is to do a full swap and ditch custom power plug and use an off the shelf universal format jack that will work with any radio shack type multi adapter.

You can get the oem connector of ebay, but you will have to know how to use a solder iron.

are most laptops able to power up just with the ac adapter and w/o the battery right? i tried power up the hp w/o the battery, just with the ac adapter, but it does not power up at all.

Yes, you don't need the battery to power up a laptop.

The jack is loose correct?

Is the other HP you have an 8440p as well? If so, charge a battery in the other one and swap it into the broken one. If the laptop powers on with the good battery (no ac), then I would take it apart to look at the solder points on the power jack. If not, then you likely have a motherboard issue. I would rule that out before buying a jack/opening it up (because it would be free and easy).

As someone already mentioned, try turning it on with only a charged battery. If it works then the power jack is broken. If it doesn't work then the motherboard has problems.

Either way, you're looking at replacing the motherboard because the power jack is soldered to the motherboard...unless you want to de-solder the old power jack and re-solder a new power jack.
