Dell PA-10 & PA-12 have internal serial ROM chips that communicate with the PC via the tiny center pin in the powerr plug.

If that pin gets bent or is not making proper contact, the laptop USUALLY complains and runs from AC adapter but refuses to recharge the battery ..

It may not be the power supply. The Battery can only take 500 charging cycles in it's lifetime. the battery could have failed or the chip on the motherboard that regulates voltage to the battery may have failed.

Easy test for power supply is with battery removed if it still powers up the laptop than the voltage and amperage are sufficient.

When im on the computer the monitor shuts off a box appears saying power saving enabling monitor to shut down in a few seconds and then it restarts


Windows provides the following plans to help you manage your computer's power:

  • Balanced. Offers full performance when you need it and saves power during periods of inactivity. This is the best power plan for most people.

  • Power saver. Saves power by reducing system performance and screen brightness. This plan can help laptop users get the most from a single battery charge.

  • High performance. Maximizes screen brightness and might increase the computer's performance in some circumstances. This plan uses a lot more energy and will reduce the amount of time that a laptop battery lasts between charges.
    Note

    • High performance doesn't appear on the battery meter by default. To turn on High performance, open Power Options by clicking the Start button ?id=4f6cbd09-148c-4dd8-b1f2-48f232a2fd33, and then clicking Control Panel. In the search box, type power options, and then click Power Options. Under Select a power plan, click Show additional plans, and then click High performance.

If these plans don't suit your needs, you can create your own power plan, using one of these plans as a starting point.

My lap has a battery problems.keeps warning me about low charging while its being charged


I am not overly familiar with laptops, but have seen some battery problems lately.

Some computers require a power supply with a third pin - the computer will run while attached to the power supply, but the battery will not charge. If you connect with HP's website, you may be able to find out what the voltage should be at the plug. If this checks out OK, it may be that the receptacle on the computer is bad - and requires more than a casual repair.

Of course, the battery could be nearing the end of its useful life. Can you borrow a battery from someone with a similar laptop? I just found a test for the battery on the manufacture's website that may be the answer to your problem.

It is most likely that your battery is shot, but you could try unplugging your power supply, popping out your battery, and carefully clean the contacts on both the battery and where the battery connects to your laptop.

Unfortunately, the charger socket in the motherboard does not drive electricity to the battery to get re-charge it. It is a typically motherboard problem(Do not confused with a power jack problem). I can not be repaired it.
Two options work always hook with power adapter or get ride of her.

My CF-29 has battery issues


I'm just thinking that this might be caused by your power supply unit that came with the laptop although I'm not totally sure about this. When you are at home what I would recommend you do is remove the battery and just use the laptop whilst it's connected to the power supply as this preserves the life of the battery. Obviously charge the battery up and when it's full use the battery alone without the power supply unit. Carry out this test if you haven't done so already and connect the power supply but remove the battery and see if you face any problems. If it is the power supply then you may need to replace that. Good luck. Andrew

E machine 510 wont charge!


Yes, remove the battery from the laptop.

Plug-in power adapter and turn ON laptop (without battery).

After the laptop starts up and Windows has settled, put battery back in the laptop.

Allow to charge for a few hours.

Pasario 6500 laptop will not charge, charger is plugged in, turned on and laptop is running on mains power but it will not charge the battery


Most likely your battery stopped recharging. Depending on what type it is, and how old it is, it could be dead by now and needs replacing.
Most laptops can operate connected to their power supplies, even when the battery is taken out.
Some batteries need to be fully discharged for them to take a new charge and perform as new, up to a 1,000 times, according to their manufacturer's specs. Others have what's called a "memory effect". This prevents them from taking a full charge, especially when connected to the laptop almost 100% of the time, and using up some of their charge only ocassionally, when they are disconnected from their power supplies.
You can get replacement ones on eBay for less than the manufacturer's advertised price.
Good luck!

Acer aspire 4920 charging mechanism failed


Most laptops, as in 99%, have one board and everything is on it. They don't really have a power supply since the AC adpater provides DC voltage already. There is just a voltage divider that take the incomming voltage and changes it to the various voltages the machine needs. The charging mechanism is also on the mainboard. I've very seldom seen a seperate power or charging board in a laptop. Unfortunately since you've already replaced the battery and the ac adapter and since the adapter is powering the laptop then there is definitely a problem with the charging circuitry on the mainboard. This isn't something one can repair unless you start changing micro components and ICs on the board which isn't recommended. Looks like a new mainboard or a new laptop is in your future if you want it to run off battery.

Another option is to get an external battery that mimics your ac adapter but that wouldn't give you a very long run time compared to the internal battery.

Don't forget to rate my solution in your premium thread as FixYa if you think I helped solve your problem. Thanks.

If you have a volt meter measure the power coming out of the power supply and make sure the outlet is good that you are plugging it into.

Try resoldering the connection on the circuit board where the power supply plugs into it. There may be a loose connection or a crack in the board that you could jumper around using a short piece of wire soldered around the break.
