AC Adapter issues Q & A.


<p><b>Laptop switching to battery while connected to AC adapter</b><br /> <p><b>Q.</b> While turned on, the laptop will switch to battery power even if connected with the AC adaptor (sometimes during boot-up, or after a while) until the battery drains out, he then goes to hibernation (the battery light is off). If no battery in the laptop, it will shut down, and the AC light will blink very fast. The battery (li-ion) will only charge up to 10%, where it then jumps right up to 100%, and will discharge from 100% to 90% then jump to 0%, go to hibernation, and fails to complete the process, shutting down. The adaptor makes a small "camera flash charging" sound, stabilizing at 19v. When charging, it repeatedly makes the "charging sound" Faulty AC adaptor? Or Faulty battery? Or Both?<br /> <p><b>A. </b>First problem: The laptop switches to battery power even with connected AC adapter. Most likely you have a faulty power jack. It's either broken or loose.

Computer charges but doesnt want to start up


Remove battery
unplug power cord from laptop
press and hold power button for a least one minute while power cord and battery are removed
insert power cord only
turn on laptop
laptop should turn on without battery installed
if it does not turn on you probably have some motherboard issues
.......
then install battery if it still does not turn ...and try to turn on
it still may turn on...I have seen stranger things happen with computers

**************
you may also want to try another power cord if you have an extra...the power cord may not be allowing enough power to travel thru cord

My battery light is off.


The battery might be dead. Batteries only have a useful life and after that they have to be replaced.

Does your laptop work ok off the AC Adapter Power Cord? If so, your battery is dead and your power cord is good. If the laptop does not work off the Power Cord then either your Power Cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. In either case a good battery will not charge if the power cord or the DC Jack is bad.

Check your DC Power Jack which is where the power cord plugs into the compute. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Hello,

There are three possible reasons why your computer is experiencing this power problem. What you need to do is to isolate the component that's causing it.

These are the parts which should be checked:
1. Power supply
2. Battery
3. Motherboard of the laptop.

Here's the procedure that you have to follow:

1.
Remove the battery from the computer.

2. Power the computer up with the power cord only without the battery on it.

3. Check if it works perfectly without any problems even if the battery is out. If it works, then, the battery needs to be replaced. (Note: Batteries are disposable parts. They usually die after 2 years of usage depending on how you use it.)

4.If no go even without the battery on it, check the ac adapter or cord if there's a light lit on the box of the cord. If no lights on it, double check the connection. If connections seem ok but no power, then, replace the power cord.

5. If power cord seem fine, check the hole in the computer where you plug in the cord. What you need to check is if there are any sign of damages. Wiggle the cord and see if there are lights lit in the laptop.

I hope this help.

1525 dell battery not charging.


this could be one of 3 things.

Bad battery
Bad AC power adapter
Bad internal power jack (where the plug goes into the laptop)

The easiest thing to do is to try and use your laptop with the ac power adapter plugged in and no battery. This should work but if it doesnt then you know it probably is your ac power adapter. But if you feel like you have to wiggle and hold the cord in then it may be the jack on the inside. The only way I know how to fix that is to take it apart and resoder the joint holding that part together to make a stronger electrical connection.

As for the battery if you let it sit out for a day it will discharge any current it currently has inside of it and then you can try again to charge it. If that doesnt work and your cord and jack seem fine then you will need to look for a new battery to replace the one that died. This happens over a couple of years as the battery life shortens over the life of the laptop and more so if you use it heavily.
