Microsoft Composite Battery Driver: system32 DRIVERS compbatt.sys (system) Composite Bus Enumerator Driver: SystemRoot system32 DRIVERS CompositeBus.sys (manual start). Windows 10 Composite Battery Driver Missing My Toshiba laptop was working fine until a few days ago. The predicted usage time (given by the battery icon on the taskbar) went down from 6 hours (ish) to around 1 hour. Didn't happen - I had a couple of issues with the S3, it went to Acer to check a different problem out and it came back with the Microsoft Composite Battery driver missing. Battery still charges so I'm going to have a go (on holiday at the moment). I also have the Windows upgrade message in the tray so it's been identified as upgradeable (I think!).

It has become a common annoyance for some older laptops to suffer battery charging problems. When the issue occurs, with your AC charger plugged in you will notice that the battery is not charging, and hovering over the battery icon in the system tray shows 'plugged in, not charging'. This can lead to automatic hibernation of the laptop, immediate shutdown at power adapter disconnect, etc.
This issue can be caused by to distinct reasons:
Heating issues - some laptops have built-in heat sensors that will stop charging if the battery, or the laptop itself gets hot. This can be remedied by turning off the laptop for a while to allow it to cool down. It may be worth cleaning the cooling ducts and CPU/GPU heatsinks with compressed air/vacuum.
Battery Driver issues - the default Windows battery device drivers may be corrupt, or incompatible with your particular brand of laptop. If the issue is persistent, it may be worth downloading newer drivers directly from your manufacturer. Below is a solution for resetting the Windows 7 default ACPI battery drivers.
Follow the steps below to fix battery charging driver issues:
Notes: If following the above steps does not fix your issue, it may be worth using a voltmeter to verify the voltage coming out of the power supply at the point where it plugs into your laptop. Some power supply cables are prone to failure after repeat bending, and adapters can fail as well. Most common laptop PSUs should output about 19 volts, and there is a label on them that lists the input and output voltages.
The 'Microsoft ACPI Control Method Battery Driver' is a Windows service that should be set to start 'On Demand' in 'Services'. The file itself is located in %WinDir%System32driversCmBatt.sys
If the battery of your laptop is non-removable:
Similarly to the above steps, uninstall the 'Device Manager -> Batteries -> Microsoft ACPI-Compliant Control Method Battery Driver' and 'Microsoft AC Adapter' (right-click -> uninstall). After that, unplug your AC adapter from both the laptop and the wall socket, shutdown the laptop, and leave both off/unplugged for a minute before restarting.
Keep in mind that if the battery is actually bad, the above may not fix your issue.

Consider replacing your battery.' I replaced the battery with a brand new one and it is still not charging. I have 0% battery all the time and can not take it off the adapter or it shuts off immediately. Any ideas? well i also got this issue but i fix this like temp solution ... 1- first unplug the charger pin from laptop. 2- right click on the battery icon and select the different plan for the battery for example if it is set on power saver select 1 from 2 i.e balanced or high performance. 3- then plug the pin again... thats it. i solve this problem every time like this when it occurs.. hope this helps. sorry for poor English. mine is still not working, ive tried all that steps and that also hassan's comment.. pls help.. i have here hp pavilion e-450.. it is still plugged in, not charging... i can do a charge when i turn off my laptop and take off the AC adapter and the battery and push the power button for about 5-10 secs then inserted the battery and the AC adapter and it worked.. BUT when i turned it on, it says plugged in, not charging. This worked for me, but don't uninstall the battery software, just 'disable'. I tried all of the steps still I am facing the issue. please help me Thanks in advance this problem is due to change in date when you go back in different year it start charging again. this means problem is related to window. Unplug the power cord, right click on battery icon, select 'Balanced (Recommended)', plug power cord back into laptop... problem solved. Hi all... I am one of the persons who are looking for the solution that plugged in not charging occurs.. Often you would perform steps that are performing operations on device manager , restarting systems , updating bios , etc... But believe me after one month of struggle today i found the solution finally. I went to market and told the technician that my laptop says plugged in not charging.He fixed the adapter in 15 minutes and said many of the times fault occurs in cable of adapter. It only costs 3-4$.And now my battery is being charged. Please do not follow any steps , its just waste of time.. Believe me i was one of them that was very much in problem and finding solutions for these... Thanks thanks I tried ds, it worked for my DELL INSPIRON, whenever I disable d ACPI......

I tried every thing on the web and nothing worked. Finalyy I twisted and moved the wire close to pin where it connects to computer and it started charging. For some reason the wire is broken in a way that it powers the computer but doesnt charge the battery !!!! so finally after 2 weeks of 0% connected not charging to now 3% and charging .. and its going up ! So if nothing works for you I mean re installing ACPI , connecting /disconnecting battery, updating Bios, changing battery etc etc then try new adapter ! i was lucky to fing the break near the pin because thats where the the my wire was always bent!

Thanks again Hey guys, I am also facing the same problem i solved it by following steps. Step 1. Unplug battery adapter. Step 2 . Go to device manager. Step3. Under batterties , disable the microsoft ACPI-Compliant cntrol method battery( it will ask for a reboot ) Step 4. After reboot plug in charger and you see battery icon is missing so again go to the device manager and enable the microsoft compliant method , now your battery seems charging. Thats all you need to do Thanks, you are right Thank you very much. the idea works perfectly Believe me or not, I just blowed some air directly into the AC plug to remove some dust that might be causing this fault... and VOILA... it´s working again !!!... and I tried everything... including some voodoo tricks....LOL... good luck everybody !
