Try your laptop with a good previously checked AC adapter (check the battery charging process). Than try your laptop with another known good battery (with the same good AC adapter). If problem is not yet identified, you should have your laptop checked by a professional : your mainboard might have a problem.

HP Compaq 610 Not Charging


If the laptop battery is more than 3 - 4 years old then the battery could be worn out. Rechargeable batteries have a finite number of charge and discharge cycles and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced.
Rechargeable batteries will fail if stored in a discharged state for long periods.

Ways To Take Care Of Laptop Batteries


Take care of laptop batteries is also become the part of using the laptop. It is consists of so many different easy. However, before take care of batteries we must have the knowledge of due to which ways the laptop battery can be affected. Like, the Lithium Ion notebook batteries wear down due to two factors, the first is "active usage in your notebook battery" and the second is "natural aging of the notebook battery". These both will wear down your notebook battery over time so the deception is to reduce their crash while still getting the performance out of your laptop battery that you need.<br /><br />The most vital thing about understanding the laptop batteries is that they are always down a small bit of their charge. The hotter the temperature, the faster laptop batteries drop their charge. So the first step of care is to keep your laptop battery cool i.e. Notebook battery manufacturers store their products at around 60F (Be careful, it doesn't help to put them in the refrigerator; however, you can damage a battery by freezing it).<br />In the second step understand the capacity that decreases with each cycle of charging as well as discharging. By itself, it is not astonishing - but when collective with the previous point, it directs to a surprising conclusion.<br /><br />Whenever you leave their laptop battery inside the machine along leaving the computer plugged into the wall that time the laptop battery is going from a constant charge-discharge cycle. However, once its charge level goes down to an encoded level (it is differ to manufacturer-to-manufacturer), the AC adapter offers extra fluid to "top off" the notebook battery. Moreover, as the laptop battery becomes older, it leans to self-discharge a little faster that speeds up the process even further.<br />Few Guidelines for Laptop Batteries:<br /><br />- As new <a href="http://www.battery-jp.com/%E3%83%8E%E3%83%BC%E3%83%88%E3%83%91%E3%82%BD%E3%82%B3%E3%83%B3%E3%81%AE%E3%83%90%E3%83%83%E3%83%86%E3%83%AA%E3%83%BC-c-1.html"><span>laptop batteries </span></a>generally arrive in a discharged state so you must charge them minimum for four hours before their first use.<br />- Keep laptop battery cool (do not put it in the refrigerator or freezer).<br />- Try to evade running your laptop battery all the way to zero.<br />- Don't charge your notebook battery before long periods of inactivity.<br />So expand the life of your laptop by following the above listed points for take care of laptop batteries.<br />

Hp 6715s laptop battery charging bat battery backup not starting problem solyution


If I understand you correctly, you are saying the computer will run with the AC adapter plugged in, but will not start on battery power even though the battery appears to be charged. Most likely the battery is defective. If it won't run on battery power with a known good battery, then there is a problem in the power control circuit on the main logic board inside the computer.

Failure to start


Will the laptop start if the battery is removed and just the charger plugged in? I would remove the battery and charger for a few minutes and try it with just the charger plugged in. Unfortunately it sounds like a hardware fault. Let me know how that goes. The other thing to try is removing the ram and then putting it back in. this will solve alot of problems like this.
