Here are a few HP laptop problems related to that concern and some ideas on how to solve them:

One of the most common HP laptop problems involve the battery failing to charge when it is plugged into the mains. Even if the battery display is at 0% and is obviously in need of charging, this number may not increase. Another common symptom is unplugging the AC adapter, which doesn’t turn off the laptop, although the warning that the battery level is at 0% persists along with a notice that it should be plugged in. This is particularly disturbing since even new laptops have been known to exhibit these types of HP laptop problems.

The first thing you should do when faced with this problem is to remove the battery and re-seat it. In some cases, these types of HP laptop problems could be nothing more than a bad contact and this should be enough to solve the problem.

In other instances, such HP laptop problems may be the result of a dead battery, which is caused by overcharging or overheating. For these problems, you may be able to bring the battery back to life if there is a reset button provided, as in the case of many modern laptop batteries.

Some of the more alarming HP laptop problems have to do with certain battery units that have been identified as fire hazards. Up to 70,000 HP batteries have been recalled so if your laptop uses one of them, the best thing to do is to stop using them and to get in touch with an HP representative.

The Memory Effect
This occurrence is normally seen in Ni-Cad and NiMH batteries, and is often caused by the battery being recharged even before it has fully used up its stored energy. This causes the battery to eventually fail to charge to its normal capacity. The best way to avoid these types of laptop battery problems is discharge the battery fully every month before recharging it.

The cost of laptop batteries
Some batteries are designed to work only with a specific laptop brand or model, which makes them more expensive, since such batteries are typically manufactured in low volumes. Unfortunately, some manufacturers do this as a way to entice customers into buying a new laptop. Conversely, laptop batteries that are manufactured in large volumes result in lower costs for the customer.

Should the battery be left in the laptop for long period even when it is unused?
This is generally not a good idea, as this will cause the battery to discharge slowly even if it is unused. In some case, the laptop may even fail to recognize the battery if it has been allowed to discharge completely. It may also be a good idea to avoid charging your battery fully before storing it.

Battery heating issues
Most laptop batteries typically become too hot to touch when they are in use. If this happens, it might be a good idea to take it out and let it cool down for a while. If the battery heats up excessively shortly after it has been placed back in the laptop, it may have to be replaced.

Storing batteries in the fridge
It may surprise you to know that batteries can be stored in the fridge to prevent them from losing their charge quickly, although you will have to store them in an airtight container.
