1 Answer

I have an hp dv2500 and it won't power on. Purchased a new power cord and battery still nothing. Reseeded the hard drive and ram nothing. Tried to power on without the battery and then restart nothing. The lightening bolt was on for a period of time while charging the new battery but nothing now. The power cord light remains on. What's the issue? I see there are problems with the pca switch (power on switch)..is that my next step?

Hi,

There's a lot of causes why this has happened in your laptop. Here are some possible causes and solutions to this problem:

Since you bought a new laptop battery, probably it is good and your AC power adapter also, because you said that the power cord light remains on. I think what you mean for the power cord is that it is the AC power adapter.

First, try to power up your laptop through the new laptop battery that you recently bought if you believe it is holding a charge and make sure you don't plug in the AC power adapter into your laptop. But before you turn on the laptop, make sure that the contacts between your laptop battery and your laptop motherboard is making a good connection. Because sometimes it will not, maybe something spilled in there or there's some dust covering the contacts or some sort of dirt and they're not making a clean connection. To be sure that this is not happening to the contacts or your laptop battery and the motherboard of your laptop, pull the battery out, take a toothbrush and just scrub in between the pins of the battery there and also scrub down the the pins where the motherboard connection is (which is the contacts between the battery and your laptop motherboard, where you install the battery). If you are done doing this, put the battery in and turn the laptop on.

If the steps above doesn't solve your problem, try this one:

* Pull the battery out
* Remove main supply
* Hold power button down for 30 seconds. This will drain the charges in your battery.
* Put only power supply in
* Do not put battery in
* Turn laptop on
* Put the battery in

If you're done doing the steps above and did not solve your problem you can try the steps below:

You have to test if there's a fix voltage on your AC power adapter by using a voltmeter, usually 18 to 19V DC depending on the registered voltage written on your AC power adapter. If there is, kinda bend or jiggle the power cord a little bit to make sure the connections is tight. If the voltage remains steady, then probably your AC power adapter is good. Now we have come to the point that we need to deal with your laptop motherboard. There's a lot of reasons why your laptop won't power on even if you have a good laptop battery and AC power adapter. Maybe your laptop motherboard is partially bad, like for example if the dc jack on your laptop is bad and is not making a connection to the motherboard then it might look like the battery is bad as well because the battery is now now holding a charge or even taking a charge. Now this has happened a lot to plenty of laptop owners where their dc jack goes bad. They think their batteries gone bad because is not taking a charge anymore, they got and buy a new battery and then decide to bring their laptop to a laptop repair company because of the battery's not charging even with the new battery, that's because the dc jack is bad. You're going to probably right into this a lot where the battery's not charging because the dc jack is bad and until you fixed that, the battery's never going to charged. So how do you test if your dc jack is bad? It's simple, plug in the AC power adapter, take the battery out of the computer. If the computer doesn't power on then you know you have a problem with the dc jack. The only way to solve this, is that you have to disassemble your laptop, start taking components out one by one and finally, take the laptop motherboard out. Afte you've taken the motherboard out, look where the dc jack is connected. After you will find it, take a file tool and file off a spot on the motherboard where you can reattach the power jack and use a wire to reattach the power jack to the motherboard.

Hope you will find this answer helpful. God bless

My nc6400 won't power up even when connected to a power adapter. How can I fix this?


Since you already tried another power cord (assuming that it was a working cord and for the exact same model). Then I would say your motherboard is dead.

New battery HP g61 is fully charged but not working \


Maybe the AC Adapter Power Cord is not working. If you can't get on the laptop with the power cord then it is bad and the battery might be drained so you have no power source to power up the laptop.
If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.

To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.

To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.

This sounds like the possibly infamous Nvidia GPU defect. It is caused by heat, over time the solder fractures and separates from the board. Typically the solution is either repair it (temporary fix) or get a new board and hope for the best.

or rma the laptop if you have warranty coverage left on the hp dv2500

My hp pavilion dv2500 will not turn on at all. I can plug up the ac adapter and the blue light surrounding it comes on but it will not come on when I push the power button.


A fast check to determine whether you have a problem with the power adapter, power cord or the laptop's battery is to turn off the laptop, remove the battery, connect the power adapter, turn on the laptop & see if it works.
If the laptop works directly from the power adapter with the battery removed, then the power adapter is good. In this case we can suspect that the battery is defective.

Another possibility would be that there is a short circuit somewhere in the power circuitry on the motherboard.

HP Pavilion dv2500 - FTB


The troubleshooting you have done seems to be fine. It does not seem to be a problem with the power supply,cord or battery.Did you try a hard reset. If there is a reset button on the bottom of your laptop, you might want to try pressing that with laptop plugged in, not plugged in, with battery, without battery and different combinations thereof.
If this does not work or you don't have a reset button read on.

Before assuming it's the motherboard, there is one other possibility. There is a part called a PCA switch. It is possible this switch has gone bad or a plug might have come loose.

If you are comfortable with doing your own work, you can obtain a repair manual for your laptop online. Within this manual, it should explain what is involved in replacing this part. It is really not too complicated.

It does not sound like a hard drive problem simply because it doesn't seem to be getting power to any other part of the laptop.

You can try these steps.

HP Pavillion dv2500 laptop won't turn on


Kinda strange. Not turning on indicates a hardware problem, you made software changes. If the software changes caused a problem, it would start, just not boot to windows. I would first tryy to reset the laptop. Unplug it and remove the battery, hold down the power button for 60 seconds, then try again. If still no go, start removing hardware one at a time, hard drive, rem, wireless card, dvd rom. You may have a bad hard drive. Your pc should boot to bios if there is no hard drive installed. If that happens, run a diagnostic on your hard drive from your bios. Let me know if you need anything else.
