Question about HP Pavilion 2.4GHz Pentium 4 Notebook with DVD/CD-RW (P424)

2 Answers

Power adapter port on motherboard fried, cannot power on laptop. The original HP adapter burned up, purchased a universal and it also stopped working. I could only power on laptop with my charged battery (I used another laptop to charge my battery). Placed battery in laptop and was able to press power-on switch and it worked. Question: Can the adapter port be removed or by-passed and a USB electric power port be installed to the power switch to allow me to power-on my laptop? (I don't have a way to recharge my battery (3 hr use span? I paid $2,000 for the laptop a few years ago and it is a shame for it to sit not used for the past 3 years. Please contact me at: liznozy@aol.com Thanks,

Get you an external battery laptop charger and charge the battery that way.  Your gonna have to open this puppy up and replace the power port IC board if you want to charge by AC cord. Your non factory charger could have fried the board.  The board isn't too spendy, but you gotta know what your doing or you will crack the case or damage other parts when opening this thing up.

Give me the exact model# on the laptop. It is not too hard to repair the power jack on some of these - of course it requires a full breakdown. Typical cost is $125 plus shipping if you can't find a local shop. If this a 17" screen they use alot of juice and many of the universal pwr (that are advert. to do the job) are not enough amps. - typically 4+ amps (90w). The power jack on the mobo gets so hot I have seen it vaporize the solder as it gets looser and looser.
As far as the USB port you can only pull power out and then only a max of 0.5 amps.

Using a Dell Inspiron no apparent power to laptop with our without a adapter. New universal laptop charger...still light on charger goes off as soon as connected into laptop power port.


hi
sounds like the laptop has a motherboard fault, dell laptops need to be run from dell chargers only and at correct voltage and correct amps output. the information is normally provided on lable on the base of the laptop, universal chargers do not normally work on dell laptops, would suggest you try and use original dell charger .

First, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether

I plugged in a laptop using a universal laptop and it fried it


Connecting a power adapter with the wrong voltage or current can be deadly for most electronics, and especially "sensitive" ones, such as laptops... If I were you, I wouldn't take the risk - and change the whole system board!

Good luck,

Exact same problem


So, i have a laptop whos power supply was struck by lightning, and both the powersupply and the power house inside my laptop were fried. The sometimes on or off is because your Adapter is fried and giving random voltages, causing the computer to power off or overload. I would try getting a new adapter, but if the power part of the motherboard is fried, i would take it to a shop and have them diagnose it.
Good Luck

No power


Try purchasing an original adapter. I've had several machine of different make through my shop that the Targus adapter just simply won't run. For example, a Dell Inspiron 1100 and HP dv4000 won't run at all, and a Dell Latitude 1501 and Gateway crv503 will run but won't charge the battery. Targus adapters are junk, if you can, get your money back.
