Hi I have a Sony VGP-BPS21A laptop. It was working fine until I noticed that the battery wasnt charging. I heard the ac adaptor buzzing a bit so I figured the ac adaptor was on its last leg. So I ordered a new one. That didnt charge the battery. So I ordered a new battery. Still nothing charging.

I shut the laptop down, removed the Sony VGP-BPS21A battery(new and old) and tried running the laptop just off the old ac adaptor.

It boots up fine and is usable but I cannot get the battery to charge whether its the new Sony VGP-BPS21A battery /ac adaptor or the old ones.

Is there anything that possibly went on the board itself?????

I have been doing some research but cant find much answers out. I read some other people having the same problem but nothing answered in several forums I have read.

Hi, there!

 

I doubt it's a hardware issue.

 

I'd suggest that you go to bios, look for a "smart battery" feature there, and disable it. If you can't find it there, look for sony utilities in windows and try to do the same.

      draw.io Desktop 30.2.6 by Razvan Serea draw.io desktop is a downloadable security-first diagramming application that runs on Windows, MacOS and Linux. Creating diagrams in the desktop app doesn’t need an internet connection. This is useful when you are disconnected or when you must create diagrams in a highly secure environment, where data protection is of the utmost importance. When you use the draw.io desktop app, your diagrams will be stored on your local device. Because this is a stand-alone application, also designed to run offline, there are no interfaces to cloud storage platforms available. Of course, you can still store your diagrams in folders that are synchronised to your cloud storage if you wish. Easy-to-use diagram editor The draw.io apps work just like the office and drawing tools you are used to using. Drag and drop shapes from the shape libraries and drag to draw connectors between them. Drag connectors to add waypoints and set a precise shape and position, or let them reroute automatically. Double click and start typing to add a label to anything. Create tables and swimlane flows with a familiar tool. Style shapes and connectors with customisable palettes, sketch options, fonts and text formatting tools. Search for shapes, including in open-source icon libraries. Use our vast libraries of shapes and templates, organised into logical categories, to create a range of diagrams and infographics. Generate diagrams from text descriptions using our smart templates.
