Question about PC Desktops

2 Answers

My laptop was working fine and then the ac adapter stopped charging, so i bought a brand new one. My laptop still does not turn on or give any response to a charge, even when i take the battery out to see if the battery is dead. My laptop is only a year old and i would really love to know what is wrong with it.

The common causes are:
Bad Power adaptor
Bad charge connector (on laptop motherboard)
Bad Battery

If you already have replaced your power adaptor (ac), try replacing the battery and see if the new battery start to charging or keep the charge, if not you will have to replace the charge connector located on your motherboard.

It is a problem with connection. You need to check with your hardware vendor

Yes i bought an emachine laptop and had it for a while now, and i was wondering, i always use it and leave it charge all night well now it won't charge at all and it won't even turn on !! Can you please...


Hi,
There could be to reasons , that the laptop is not charging.
1. The battery may have reached end of its charging cycle( Laptop batteries need to be replaced after 1 year to 1.5 Years of use)
2. A faulty ac adapter can also cause the same issue.

The best step forward, would be first try checking it with an alternate adapter.

Thanks for using Fixya

Compaq nx6320 won't power up


Replace your battery Some laptops don't boot up when no battery is present even it is connected directly on the power supply. Or if not to visit your nearest HP service center. If its still with warranty, use it.

Good luck kabayan. ^_~

All you need is a power plug adapter. At Radio Shack you can find one for US plugs to any other plug in another country. They will be able to order a reverse adapter, one to adapt Aussie plugs to US plugs. I'd start there and they'll find you one no doubt about it.

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.

Acer aspire 4920g charging mechanism failed


Have you tested the adapter to see if there is any power getting to your notebook period. Use a multimeter to check for DV voltage. If you can't get your multimeter probe into the middle of the plug then I use a paper click to get in there. If your adapter is not supplying any voltage then there is a problem with it. I get a replacement adapter for my wife's Acer on eBay for about $30. Just search eBay for 4920g and you should get quite a few hits for the ac adapter or power cord.

If the adapter is providing power then the motherboard in your notebook is faulty since you've already replaced the battery. A replacement motherboard might be available from eBay. Replacing the motherboard could be complicated depending on your experience so I would leave that up to a notebook technician. An Acer certified shop may also be able to sell you a replacement motherboard.

I don't think it's the motherboard, my money is on the adapter. Test it out or have it tested.

Hi when i turn my ACER 5315 LAPTOP on it runs for 5-10secs before turning off again please help thanks


Hi,


We can try some work around to narrow down the issue.

I think your notebook might be getting power from the Ac adapter. The remaining power in the battery might be giving power for few seconds and trning OFF again.

To check this, once remove the battery from the notebook and turn on the laptop with only AC adapter.

If there is no power at all, then what I guess is correct. Issue might be with the AC adapter or with the power jack on the motherboard.

If the notebook turns ON even with the Ac adapter and turned off aftetr few seconds without battery, then you have to contact service center as it could be the hardware issue.

Need an ac adaptor for laptop in paducah ky


To give you a specific answer as to a specific model system, you'll need to post the brand and model of your computer.

Here are a couple of web sites you can check out:

AC Adapter stopped working


SmitFraud is not capable of doing actual hardware harm. It can be a pain to get rid of it software wise, but it can't do any harm to the physical machine. I think you've just had bad timing with this problem.

If the charger isn't charging, there's one of two problems. Either the charger itself is faulty, and it's not thinking the battery is charged when it isn't, or the battery is faulty. I would personally take your laptop into a shop that sells the same kind, explain the problem and ask if you can plug one of their adapters into your laptop. If the light comes on and immediately goes out, it's the battery. If it comes on and stays on, it's your charger. Either way you can find out which it is before you have to spend money on a replacement. Do be sure to do it with the shops permission, though - they won't like it if you help yourself, and you might find yourself swiftly banned from the premises.

It could be one of three things. It could be a bad battery, a bad ac adapter, or the recharging circuitry could be bad. I would try pulling the battery out, and see if the laptop will startup and run strictly off of the ac adapter. If that does not work, you have a bad ac adapter. If that works, and the battery has any charge left, try running it strictly on the battery. If it doesnt work, you have a bad battery. If it does work, the circuitry is bad and you will probably need new motherboard. One other thing you can check is where the ac adapter and battery plug into the laptop, and make sure there is no corrosion that could be causing a short.
