Notebook AC adapter (Laptop Battery Charger)

This part, like the batteries, Hp laptop battery,is an essential element of your machine and is also the cause of a great number of breakdowns. Indeed, one of the elements most fragile of your laptop is the AC connector, i.e. the connector female in which comes to plug in the plug of your Laptop AC adapter.

 

The repetition of these plug in and sometimes their useless violence ends regularly up tearing off the female connector of the motherboard. That often occurs by stage, initially light poor contact, then as you move the cable in all the directions to find the current, the connector is torn off definitively, PCGA-BP1N,or the produced sparks roast the motherboard.

An adapter in bad condition is often the cause of a fatal electric problem to the motherboard of your laptop. To avoid that you just have to purchase a new laptop AC adapter, it is always less expensive than a repair or a swapping of the motherboard.

About the compatible adapters.

To try to save some dollars (whereas often the genuine adapters are not much more expensive) PB991A ,or simply because their retailer does not propose a genuine adapter, much buy "compatible" adapters. Let me be frank, for repairers these adapters are a blessing! Their male connector, relatively adapted to the socket of the laptop, tears off more often than others the females connectors.

Their voltage and their amperage more or less close to the needs for your laptops and a sometimes irregular flow, even straightforwardly random, and their annoying tendency "to kill the fuses" 398876-001, PB992A, PB994A, PB991A by at the same time roasting your motherboard and other power cards, are an important source of occupation for the technicians. The failure rate, properly incredible, due, in an unquestionable or probable way, with these adapters makes that I dis-advise them formally. I am the first to propose to use compatible parts when they are less expensive and as powerful as the original parts. But for the AC adapters I advise prudence.

Testing Laptop Batteries

During their working life, rechargeable batteries in a laptop are repeatedly re-charged after they have been drained. The charging is accomplished by applying externally supplied electrical current through an adopter.398876-001, PB992A, PB994A, PB991A The electrical current enters in the laptop battery and reverses the chemical process which occur in the battery while it is in use. Devices to supply the appropriate current are called notebook battery chargers.

Most of today's laptop computers are powered with li-ion batteries. Rechargeable notebook batteries have a tendency to self-discharge.PB992A, This means they discharge even while not in active use. This self-discharging process accelerates at higher temperatures. It is not advisable to leave them unused for long time, due to their poor shelf life.

Under good conditions, a typical li-ion battery can supply around 500 discharge/charge cycles, which is equivalent to 2 to 3 years of service, from the time the battery goes through the production process. As a battery is put into regular use, capacity loss occurs as a result of increased internal resistance caused by cell oxidation. Eventually, the resistance becomes so high that the battery can no longer deliver the needed energy to the laptop, even though the energy is still present in the notebook battery. This usually marks the end of the useful life of a battery. It is believed that there are no remedies to restore the battery capacity when it is worn out.398876-001 battery, Heating the battery will improve its performance only momentarily and can not be considered a long term solution.

There are many free utilities available on Internet and from software developers that help in the testing of battery status. A typical utility constantly revises its estimate of remaining battery life, by measuring the time it takes to run it down. Such utilities are particularly useful when batteries read 100 percent when fully charged, but only run a few minutes before they run out completely. A power center would accurately show a 100 percent charge but it would also show about 5 minutes of time left.
