Immediately after downloading and installing Windows 10 on to my Dell XPS 15 laptop, I began seeing an error message on a black screen upon bootup: "AC Power Adapter and wattage can not be determined. Battery may not charge." I am using the power adaptor that came with the laptop: Model DA130 PE1-00. From what I can determine, this is the requisite 130 W device.
The laptop originally was installed with Windows 7 and that is what it has been using until this Windows 10 install.
When I rest my cursor over the battery indicator icon on the taskpane at bottom of screen, I see this message: "89% available. Plugged in, not charging." Yesterday, it read 92% charged.
Additionally, since the Windows 10 download, the fan has been running constantly. (I imagine this is unrelated to the adaptor message. If I should post that separately, please let me know.)
Purchased in fall 2011, the laptop, although a powerful one and seeming to run well, is no longer under warrantee.
I appreciate your guidance.
