Windows 7 Plugged in Not Charging (HP DM1)

TLDR; Ubuntu/OpenSUSE ftw

I got a netbook free, because it had some flaws, including  a charging issue, being plugged in but not charging.

The symptoms where that if the battery was allow to completely discharge, such as sleeping in a bag for a few days, it would allow ac operation but not charge.

I tested different batteries with the same outcome. Other similar laptops in the fleet did not have this issue.

I found that this could clear it up sometimes.
Disconnect AC
Shutdown
Remove battery
Connect AC
Startup
Under the Batteries category, right-click all of the Microsoft ACPI Compliant Control Method Battery listings, and select Uninstall (it’s ok if you only have 1).
Shutdown
Disconnect AC
Insert battery
Connect AC
Startup

But it turns out, the real reason that it wasn't a big problem for me is that I swap out between a Linux HD and a Windows HD.

Yup, charges just fine under OpenSUSE or Ubuntu.

Yup, not necessarily a hardware problem, but a Windows driver issue.

Yup, and people still talk about Linux being difficult and having driver issues.
