These computers are notorious for this, the power plug, on the cpu, the power lead of these break easily, take it apart and resolder the connections, should be 100%, or take it in to a professional, about 100 bucks

Battery not charging at all


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

NEW Battery not properly charging


Batteries have electronics data that software has to get to properly charge it. Newer lithium batteries maybe different. But apparently, you have a work around for a lengthy use of the new battery.

First of all, 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.

Why does laptop stop working through adaptor after battery flat


Hi There,

Your battery charger/adapter connects to the DC Power Jack to power your laptop and charge the battery. Since the charger/adapter does 2 things, there are 2 "cells" inside it to do those 2 different things. It's not uncommon for one or the other (but not both) to fail. So, often just purchasing a new charger/adapter solves the problem you're having. It appears that yours is continuing to charge but has stopped "adapting" AC current to DC current to power the laptop directly.

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

Battery doesn't stay charged


The problem is with the battery. All Lithium batteries last for around 1000 charges or so. Since the laptop is 2-years old the battery needs to be replaced.
I Hope this solves your problem. Kindly Accept my solution.

Compaq evo n610c battery not charging


Hello All;
I used to have these same problems. I replace my BIOS battery, which I know was dead, because all settings get reset when I unplug the power and remove main battery. You might not have to replace it if its still good. Back to the main battery problem, You have a good change of solving this by going into BIOS, and under Tools there is a Battery Calibration option. Do the calibration for the main battery and-or other optional batteries attach and it will most likely solve the problems. This calibration process will take a long time; 1-charge, 2-discharge, 3-recharge, so leave it over night or however.

There was a mention of updating BIOS. This could solve the problem too, because BIOS controls the charging unit. Also, make sure you have Compaq Power Management install on your OS, (download at hp.com).

One note: it will not charge if the battery is about 93% or higher. 93 is not exact, but close to 90%. so test by discharging to below 90% and it will start charging again.

If anyone tries this, leave a post of your success or failure.
