Re: hp pavilion n54212L

To turn on an HP, make sure you have the AC adapter plugged in properly, and press the power key. But since you imply it has been a while since this was on, I suggest removing the battery BEFORE you start the first time.

The power key is identified by an ICON best described this way: a circle with a vertical line in the center. The vertical line is sometimes centered in the circle without touching any edges, and sometimes it is crossing the top of the circle slightly.

Once you have started the laptop and get to an OS desktop, you should check everything out to make sure everything works.

Then SHUT down, remove the power supply, insert the battery, reattach the power supply and start again.

Monitor the battery charge progress carefully. If the battery fails to charge, it will need to be replaced. This is because no matter how new a battery is, if it is left for extended periods in an uncharged state (or worse, fully depleted state) the battery will usually be defective. It cannot ever be recharged because at least one cvell will be dead.

As for the power cord, using a three-prong plug will be useless if you do not have a 3-prong jack and 3-wire cable. but if you do, you can cut off the useless 2-prong euro plug, strip the 3 wires and install a 3-lug grounded plug. Pay attention to the polarity then, because it is critical on 3 wire connections. In USA, black, white and green are the color codes. Green is the ground. In Europe, the colors are different and varies widely. Blue or brown will be the ground. You will need a VTVM to trace the continuity to the other end, to identify which is load, neutral and ground (earth). Be careful. Ifr you connect AC load to ground, you may damage your PSU -or the HOUSE !!!! :)

My HP Pavilion DV5000t 1.6GHz Core DUO Centrino Was on and suddenly went out, when I press the power button just blinks the battery icon two or three times. What could it be?


The battery is discharged, you would need to charge the notebook. If the power is plugged in and still the issue is there. Remove the batter and connect the power cable without the battery and turn on the notebook (without battery). If it turns "On" the battery has gone bad.

HP DV6917cl Pavilion laptop Quicklaunch lights will not turn off


From what i can remember with HP laptops there are two ribbon cables that rup up the left hand side of the laptop which both look the same. One to the power button the other to the LED's and hot keys on the keyboard bezel (plastic strip that runs above the keyboard)

You may have accidentally used the wrong cable in the wrong slot. Try reversing the cable. power on and see what happens. You can also try to switch ends to see if that helps.

Let me know if there is anything else.
