Battery not recognised/not charging


Turn the computer off, unplug it, take the battery out. Then hold the power button down for 10 - 15 seconds. Plug the ac adapter back in, but do not put the battery in yet. Boot the computer, then shut it back down. Put the battery back in then boot it again. It should recognize the system now.

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.

Charger not recognised


Hi,

I believe this is a known problem, all you have to do is to Download and install the BIOS update on the support website support.dell.com . After installing the BIOS update and still the charger is not recognized, it only means the motherboard needs to be replaced as well as the ac adapter. If you are still covered by the warranty, call dell tech support and they will replace the motherboard and ac adapter.

Hope this helps.

AC adapter not recognised


Try charging the battery on one of the other dell's.
If the unit runs for any lengh of time, it is not the motherboard.
It could be the A/C adaptor jack on the side of the unit.
Log a complaint will dell's customer care.
