Detailed description:Hi, I have an issue with my UX450F. I totally love this notebook, but this issue is totally killing my love for it!

When my book is in sleeping mode, it doesn't matter how (pressing power, from start menu, inactive time or closing lid) it sometimes immediately drains battery to 1%. Even though it was 100% and my battery life is normally between 4 and 9h, it drains to 1% in a minute. When I power it on again, I see the regular Windows login screen and a few seconds after it goes into deep sleep. After that, I can press power for 15 seconds, but the only solution is attaching the AC power. After that it looks like it's charging from 1%. But that's just impossible after a 60-80% or more charge..

I couldn't find a similar case. I'm wondering what to do. OS clean install rather not, takes a lot of time and I'm not sure if it will fix this issue.

Hoping someone has a brilliant solution.

Best Regards, Frank
