Chosen Solution
I have a Dell XPS Studio 1645 (bought late 2009) the warranty has expired so no replacement possible with Dell. I bought a new battery and it isn’t recognised. (I hit the MS-DOS screen with option F1, F2 or F12) I read to uninstall “microsoft ACPI-Compliant control method battery” in the setup configuration. But it isn’t working : the power still runs the laptop but doesn’t charge the battery. I tried the same with the old battery : same issue. I bought the Dell Studio XPS 1640 / 1645 / 1647 DC Power Input Jack with Cable as a lst resort. I connected that power input jack and checked if it was charging : no success. Anybody have any other suggestions ? Much appreciated, Thanks V.
it could be from the connector or IC inside the laptop. CMIIW
