Hi i am max.Most of the laptops can work without the battery by removing them and connecting to the power supply directly through the cord.However if the battery is already there and the power cord is also attached to supply and switched on then the battery comes into play.As long as the supply is on battery charges and powers the laptop and when the supply is turned off it discharges and keeps the laptop running as long as there is enough charge in the battery.There is usually a small icon at the down right corner of the screen that shows the status of the battery.

I hope to have answered your query.

My mb511 won't power up


Is the laptop charger question or the laptop motherland question?
Check them carefully, then you could solve your issue.
Charge it with another charger to check if it works or not, if works, that means the laptop charger is broken.

The battery charger is not working.


I too had a problem with my chair not charging. I found out that my on board charger is bad. It's very costly to replace. However, I found a work around. I bought a off board charger from amazon for 13.94. It's listed as: 24V 2A Scooter battery Charger with XLR connector.It plugs in under the joystick. It solved my problem. Good luck.

When i put my charger my mouse pad is not working


  1. It might be due to touch-pad drivers.
  2. Use a system utility tool like Reginout to fix windows registry errors.
  3. Reinstalll Touch pad drivers.
  4. If the problem still occurs then Its due to charger. Change the charger that you are using. Use a charger whom Power(Watt) is less. Hope problem is solved.

Not charging Acer Aspire 5732z, now won't turn on!


If it does not work with the Charger while the battery is out then I would say either your charger is bad, the dc power jack where the charger plugs into the laptop is bad or you've got motherboard issues. Does the charger have a light on it to indicate that it is on when plugged in the wall? Do you see any lights when you plug the charger into the laptop?

Take an ink pen and see if the little pin inside the computer where the charger plugs is loose and moves a bit. If so that is probably your problem. If the pin is tight and the charger works, then you've got motherboard issues.

My compaq cq40 laptop charger is not working


Before you make a decision about the next step, maybe you would like to know why the laptop charger is not working. Here are some commonly found reasons for this problem.
  • You have been using the wrong laptop charger for your machine, or someone else has been using your laptop charger for another machine. This may seem like a harmless act, but it affects the battery on your laptop, and charger you are using as well.
  • Your laptop battery has become weak and worn out from excessive use. Due to this the battery is not charging at all (or charging very slowly) when you plug in the charger. In this case there is absolutely nothing wrong with the charger itself.
  • The wire of the laptop charger has got a distinct curve at one point, and this is restricting it from transmitting power. You need to look out for such bends in the wire, as this will ruin the efficiency of the charger in no time.
  • This may sound elemental and stupid to some, but it does happen to many people. Maybe you are simply using the wrong laptop charger by mistake, or maybe you have failed to switch on the power switch. Check both these things to be sure.
Any of these potential causes could be the reason behind your laptop charger not working. As a result of these, either the mains power lead of your charger may be damaged, or the power supply unit may be damaged, or maybe the lead itself is damaged or broken somewhere, or some circuitry inside the laptop is damaged, and not responding to the charger. It's hard to accurately tell which of these problems could be the real cause of your laptop battery not charging, without physically examining the machine.

Solutions and Answers

Now if you are well versed in computer hardware you can attempt to fix this yourself. Most people cannot do this, and it is advisable for them to visit a computer repair shop instead. They will examine the laptop charger not working problem, and suggest some suitable remedies for it. Depending on your budget, you can choose an option that suits you and simultaneously solves your problem. Here are some recommended solutions.
  • Buy a brand new charger which will definitely solve your problem of charging the laptop for a long time.

  • If you're hesitant to pay that amount, you can try and purchase a second hand laptop charger from eBay.
  • Get your's repaired and pay the repair shop the fees that they charge.
  • If your warranty is still valid, you can simply get the laptop charger replaced.

My charger doesnt work what i do to solve this


First, try to isolate the problem to make sure that the charger is defective.

Try using a known working charger and see if your device will charge. If it does, then buy another charger. But if not, slowly wiggle the charger connector and see if the power jack is loose.

If you find out that the power jack is loose, try to use a long nose pliers and turn the power jack clockwise to tighten it.

Good luck and have a great day!

I suggest you a few steps to solve your problem.
  • remove the charger and press the power button till all residue power is radiated.
  • then connect the charger and charge the battery fully and try booting the system.
  • if this don't work check the output of your charger and see if it is working fine.
  • if it is working fine then remove the battery and connect the charger and try starting the system.
  • if it works then there are two things possible.
  1. battery gone.
  2. IC responsible for charging is gone.
if this don't work out then your RAM is gone.

i hope you can figure out the problem through this.

Thank you.

No charger recognition


Hopefully you have damaged the charger and not the phone. Go to Best Buy or Radio Shack and attempt to plug in another charger, if that works, just purchase the charger. If not, you have damaged the phone itself and can only be fixed by an authorized repair center!
