Hello,

I think the problem is the battery you just fitted since you are able to use the adapter to run the computer, this indicate that the battery is either flat or bad, you will need to get another battery to run your system because the adapter is still very much ok since it runs the computer but could not charge the battery. The battery is the problem, get another battery.

Take care.

Msi wind u160 runs on mains power only


If your laptop works fine while plugged in but stops working while unplugged it's likely that either your laptop battery is bad or your laptop is not charging the battery properly.

Below are steps that can be taken to help identify the cause of this issue.

Leave power plugged in


Make sure the computer has been charging from the power plug for at least two hours before attempting to unplug it.


Remove and reconnect battery


In some situations the battery can become loose.
Removing it and then put it back into the laptop.

Third-party utility


Use a third-party battery utility to determine the total capacity of the battery. For example, BatteryCare is a free software utility capable of doing this.


Replace battery or AC adapter

If your computer is still in warranty we suggest skipping to the next step.


If the above steps have been completed, we suggest replacing the battery in the computer or AC adapter.

In most situations it's a bad battery.


hope this helps



Try removing the battery from the back and then running it directly through the AC adapter. Sometimes the battery and AC adapter have conflicts and it can cause a laptop to become inoperable.

If this doesn't fix the problem in any way, I would recommend trying a new battery or AC adapter.


hope this helps

NEW Battery not properly charging


Batteries have electronics data that software has to get to properly charge it. Newer lithium batteries maybe different. But apparently, you have a work around for a lengthy use of the new battery.

Not charging batteries


It sounds like you are using a 65 watt AC adapter or an Auto Air Adapter.
The system needs a 90 watt adapter to charge the battery while the system is on.

My battery on lm70 express laptop only charges to 70%.fitted new but same problem.charged in another comp.and charged fine.


How do you know that it has charged to 70% and it is the correct percentage on your Laptop?May be you need some other program that are available on the internet that will tell you the exact charge percentage. Make note that In many ways, lithium-ion is superior to nickel and lead-based chemistries and the applications for lithium-ion batteries are growing as a result. Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns.Removing the battery from the laptop when running on fixed power protects the battery from heat. Make sure the AC Adapter that you are using [on both laptops] is supplying the correct voltage and if possible check with Load.

Dell Inspiron 5160 won't charge.


wow, ive never seen a computer know what type of adapter is plugged into it... it definately sounds like a power system problem. three parts to this- the adapter, the battery, and the motherboard of the laptop, since that is what interprets and passes on the power from the batter/outlet to the rest of the parts of your computer. we're hoping it isnt the motherboard not recognizing your power subsystem...

but you took a good guess to replace the adapter. you want to make certain the old adapter-- the voltage etc that's written on it in plastic somewhere- that it matches exactly with your replacement adapter. (You just cant plug these thing into any computer it fits into, they have different requirements sometimes, even though theyre all laptops). If it does, then yes, I would assume it's the battery.

Try taking out the battery and running straight off the current, can you do it? Technically, you shouldnt need the battery, it will just act like a desktop computer.

You can get a reasonable aftermarket latop battery for 100-135 bucks, chinese. Compare it to what your manufacturer wants to charge you for a replacement.

BTW- youre out of warrantee, right?

Good luck!

Toshiba satellite A210 11-P crashes when i disconnect the power lead


From Toshiba, try step-charging the battery or Battery conditioning procedures:

Batteries don't last forever. All types of batteries gradually lose their ability to hold an electrical charge as they age. Eventually, the computer's battery charge indicator may show that the battery contains less than a full charge, even though the battery has just been fully charged. The computer will then not run for as long a time from the battery as when the battery was brand new.
You may prefer to simply replace the battery if this happens, but you may also wish to try 'step-charging' the existing battery per the following instructions.
This procedure should work for the battery in any Toshiba notebook. Follow it only when you find that the computer will run from the battery for just a short while.
Check the User's Guide for more specific information about charging the battery in your computer .

Procedure

Step-charging the computer's battery

  1. Unplug the AC adapter from the computer, and turn ithe computer on. Let the computer run from battery power until the computer turns off, indicating that the battery is fully discharged. Time this interval, but not with a software clock running on the same computer.

  2. Remove the battery pack from the computer.

  3. Unplug the AC adapter from the computer.

  4. Wait at least 30 seconds. The first time through this procedure, use a soft cloth to wipe the battery pack's contacts and the AC adapter's plug.

  5. Re-insert the battery pack.

  6. Plug into the AC adapter into the computer again and check the fit of its plug in the wall outlet, making sure the connection is secure.

  7. With the computer turned off, let the battery charge until the battery status light or icon glows green, or otherwise indicates a full charge.

  8. Unplug the AC adapter from the computer.

  9. Remove the battery.

  10. Wait at least 30 seconds, then re-insert the battery.

  11. Plug the AC adapter back into the computer.

  12. Let the battery charge again until the battery status light turns green or otherwise indicates a full charge, again.
Repeat this procedure, starting from step 1, at least three times. Each time, check to see if the computer runs longer from its battery than the previous time.

Battery Conditioning:
IMPORTANT!!
Interruptions in the charging cycle can be responsible for an issue called "memory effect" which may reduce the battery's charging capacity. Whenever you suspect the battery performance is not at it's optimum you should try using the following "Battery Conditioning" procedure.

Before you start: Turn off your battery saving features temporarily.

***IMPORTANT*** Repeat the following steps 2-3 times!

  1. Unplug the power cord from the computer
  2. Turn the computer on and let it run until it shuts itself off.
    Note: Using the CD-ROM to play an Audio CD will speed the discharge.
  3. Plug in the power cord (While the system is off) charge the battery until the battery light changes from flashing green to solid green
  4. Remove the battery for 30 seconds and then replace it.
    Note: If the battery light isn't lit, wait a few moments, if it still does not light check your power connections.
  5. Continue charging the battery until the battery light turns solid green once again.
    **REPEAT THIS PROCEDURE 3 TIMES**

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
