Hp 8440p battery won't hold a charge

Since you have replaced the battery and the ac adapter then there's a problem with your computer's motherboard. Get it serviced by a technician if he says that you need to replace the motherboard then you better buy a new laptop. Motherboards are expensive.

Looks like the CMOS battery is dead. Open up the case and check the motherboard. You will find a small battery. Buy a new one and replace it and see what happens. will have what you need or if you are lucky radio shack will have it.

Motherboard batery need replacement. Where is located?

on most motherboards the CMOS battery is a small silver disc no larger than the size of a U.S quarter dollar coin (actually a little bit smaller).
The battery is typically mounted in a slide in holder. Simply slide out the battery when the computer is shut down and then replace it ensuring you match the battery polarity when you put it back in. For eg if the flat battery has the positive side facing up (indicated by a + symbol) make sure the replacement goes in the same way.
These flat disc-like batteries are quite similar to the batteries found in some larger watches and are easy to buy at most computer shops or electronic shops. Most batteries fitted in motherboards start with the letters CR and are followed by 4 numbers. eg CR2016. The number is clearly visible on the battery. You might have to buy an equivalent if you can get an exact match. If you need some more help just ask me.
Thanks, Steve

How to change cmos battery

Locate your CMOS battery
cmos.gifOpen the computer case and find the battery on the computer motherboard, verify that it will be accessible and that it can be removed. Most computers today use a coin cell CMOS battery as shown in the image to the right.
If you are unable to locate your CMOS battery you will need to refer to your motherboard or computer documentation and/or contact your computer manufacturer for additional assistance in locating it.
Obtain battery information
Unfortunately, most manufacturers will not list the exact type and model of your CMOS battery; therefore, once you have located the battery, write down all information about the battery (Voltage, chemistry, wiring, and packaging). If possible, remove the battery and take it to the location you plan on purchasing a new battery from.
Additional buying information can be found on our battery buying tips page.
Removing the battery
Caution: While in the computer make sure you're aware of Electro Static Discharge (ESD), your computer is off, and that you're properly grounding yourself. Especially before removing the battery.
If you're computer is using a coin cell battery similar to the above example picture. Removing the battery is relatively simple. Simply use your fingers to grab on the edge of the battery and pull it up and out of the container holding it. Some motherboards have a clip holding the battery down. If your computer has this clip you may need to use one had to move the clip up and the other hand to pull the battery out.
Unfortunately, not all CMOS batteries are removable; some manufactures will only allow a replacement battery to be added. If you're not using a coin cell battery and are not able to determine how to remove it refer to your motherboard or computer documentation and/or contact your computer manufacturer for additional assistance in removing the battery or how to insert a new replacement battery.
Users with computers that do not have removable batteries only options to install a new battery will most likely also need to set a jumper when adding the new battery into their computer.
Insert the new battery
Once you have purchased a new battery, remove the old battery (as instructed above) and replace it with the new battery.
Enter CMOS values
Once the battery is replaced turn on the computer and enter all values back into CMOS or set the values back to the default settings. Additional information about getting the values back to default can be found on document CH000970.
After the values have all been entered make sure to save the settings before exiting. Many CMOS setups allow you to press a key (such as F10) to save values and exit all in one action.
If after following all the above steps you continue to experience the same error when your computer starts and/or your computer is still unable to keep the stored values it's likely that you're experiencing a more serious issues. Most likely causes are bad power supply or bad motherboard.

Not Charging Battery


Problems of battery not charging is caused either by a faulty battery, or motherboard. Check if you are still covered by warranty. In some laptops, they replace the motherboard and ac adapter.

Hope this helps

Dell Inspiron 1505; Battery does not charge; DC jack is loose..

The loose connection for the AC adapter means the motherboard needs to be replaced or the AC adapter jack on the motherboard needs to be replaced. (With Labor, it is about the same cost to buy a new motherboard as it is to have the old one fixed)

Motherboards are available on EBay for around $100

if the cmos is the problem or not sure remove the screws and find the batteries connection or buy a new one and get batteries anywhere in the world.....

cmos error, the battery for the cmos needs to replaced or look to see on the motherboard some thing with 2 or 4 pins or jumpers,
next to the jumper will habe in writting batt. or symbol big dash and little dash and big dash and little dash with lines in the middle of the dashs indicating line meaning leads or connectors for a battery device, buy the battery pack or remove the silver round disk on the motherboard and take it to anystore that carries that type of battery or batteries plus located all over the usa, foreign countries computer or electronic store, computer junk yard would even have them.

buy the battery pack that hold 4 batteries and you replace them without having to drive around looking for batties becuase that one takes AAs or AAA's and the are 1.5volts too and you can figure out how much power you need.


ps the best way and the cheapiet to find out if you have to buy a whole new motherboard first!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Laptop Problem

Its usually the culprit. If you are on a PSP with Best Buy they might be able to replace your battery at no charge.

I used to work at Best Buy so here is the scoop. Bring in your notebook ASAP to Best Buy. Take it to the Geek Squad counter and tell them that you have a service plan and would like a new battery. Under your service plan you are entitled to a battery replacement. What they will do is order you a new one, and have it sent to the store. They might tell you that you have to have it sent off for service, but in actuality they can just send the order in without your notebook. As long as you go in prior to the expiration date, and the order is sent in before the PSP expires, you should be fine.
