My hp wont charge it comes on four about .15 seconds thats after its loaded up

The battery connector in the Nexus 7 (2012 model) is notoriously problematic. Sometimes dropping the device can cause issues that prevent the Nexus 7 from charging altogether. A hard reset may not work. Fortunately, it is quite easy to fix.

However this will void your warranty.

Pop the back of the Nexus 7 case open by pushing a credit card or guitar pick or small screwdriver under the edge of the black plastic case. Start from the top and gently pry the case open, working your way around. The back of the case will come off quite easily. The battery occupies the bulk of the left-hand side of the unit, and a group of six wires come out of the top of the battery to a connector on the circuit board. Gently push the plug out of the socket connector, wait 15 seconds, and push it back in. Snap the case back on and plug in your charger. You should now see the battery charge image appear.

1.Check the device's battery level for at least two bars of strength.
2.If the battery level is low, charge the battery.
3.If the issue is not resolved, remove the back cover.
4.Remove the battery.
5.Wait 10 seconds.
6.Press and hold the W key.
7.While pressing down the W key, re-insert the battery.
•The device restarts and after approximately 15 seconds, the 'Recovery' screen appears
•Release the power button but *continue holding the home button*, for another 30 seconds.

charger is faulty or dcjack is damage and might need a replacement. ie the socket where you plug the charger into.

With an extensive use of the notebook,
some times notebook would store some static charges which
indeed will stop the notebook from powering up or charging
the battery. The procedure to remove this static charges from
the notebook is known as power drain. Performing a power
drain procedure will not effect any personal data or delete
any pictures from the hard drive on your notebook.
I recommend you use Power Drain procedure by following these
steps:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.


and then after that do the BIOS update from www.hp.com .

On the the IPAQ 6515 and others, there is a USB Power option that you must enable to 'slow' or 'fast' charge from USB connection.
