My posting today is a total departure from the usual subjects and issues on which I comment.
I have been beset with a problem on my laptop – a Dell Inspiron 1764 – which Google searches have shown to be a relatively common problem affecting laptops irrespective of the manufacturer – and therefore not confined to Dell. I use Windows 7 but the problem also affects other operating systems such as Vista and XP.
What happens is that when one tries to charge the battery a message appears that an incompatible adapter is being used and therefore the battery is not charging. However, power is being transmitted to the laptop and one can continue to use it but the battery will not charge.
The causes for this problem apparently vary: some say it could be a defective charger, others suggest that the battery is defective and quite a few people say that the problem is with the motherboard. Some claim that reverting the bios to an earlier version seems to solve the problem. Others suggest that it is a bug in the Windows operating system. Some people, whose laptop is out of warranty, have spent a lot of money trying different fixes.
I am using the charger that Dell supplied with the laptop so I know that it is not an incompatible charger. Tests have shown that my battery is fine. I doubt if it is the motherboard on my laptop since the fix I have outlined below takes care of the problem – at least for a while.
After endless googling, I came upon a solution almost by accident that someone said worked for them. I tried it out and, lo and behold, it took care of the problem – although from time to time when the problem recurs I end up having to repeat the process. I claim no credit for the fix – it was posted on this site. But it took me forever to find it so I thought that I would make it a blog entry in case someone does a google search and ends up on this blog.
Here are the steps to take – slightly more detailed than outlined on the above site:
1. Disconnect the AC from the laptop
2. Shutdown the computer
3. Remove battery
4. Re-connect the AC
5. Startup the computer
6. Go to Control Panel and open Device Manager
7. Expand the Batteries category and right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall . You may have just one instance of it.
8. Shutdown the computer
9. Disconnect the AC from the laptop and unplug the connection from the wall socket.
10. Re-insert the battery
11. Re-connect the AC
12. Startup the computer
This worked for me – though once in a while I end up having to repeat the process. If your laptop is still under warranty, obviously the best solution is to contact the manufacturer. But if you are out of warranty giving this fix a try may save you needless expenditure. I don’t believe that taking the above steps will adversely affect your computer – but, it goes without saying that you do so at your own risk.
