Sudden battery drain

[greatg67]

Well, today I was working away with 30% battery available. Then all of a sudden a warning message popped up saying I had 7% bat life left and before I could reach for the plug the system either went into hibernate or shutdown? It took two reboots to get the wifi working properly again.

I have never experienced such a drastic power reduction, prior to last weeks update (30% to 7%) in a few seconds!

Did you read the message? It may have said your battery is draining at a rate of 7% per hour (based on the task you were doing at the time). Or maybe you are right.

I've been having the same problem! It's either a battery problem or something with Windows.
