Windows 10: Battery drainage while on sleep mode.

My laptop's battery drains fast in sleep mode though its a newly bought laptop that has a good battery health. After putting the laptop into the sleep mode correctly the battery drains about 10% per hour. I tried almost all the techniques which were in google by disabling the usb devices while on sleep mode etc. The design capacity of the battery is 37, 130 and the full charge capacity of the battery is 34, 979.

Battery drain while in sleep mode (Windows 10)

Hello Dave,

Thanks for your reply.

I don't think that is normal. We are talking about excessive battery drainage...I also have a Macbook pro - when that one is in sleep mode it barely drains any battery - unless I leave it in sleep mode for a week. Here we are talking about a battery drainage from 100% to 0% in 6 hours...that's more than when I am actually in full working mode on the computer.

Also, the problem does not occur when I have not previously had the laptop connected to a projector via HDMI...so clearly, the issue is linked somehow to connectivity with something that is not there anymore.

I appreciate your attempt at helping...but did you actually look at the screenshot showing the sleep study report?

Thanks,

Niki

Then, what could be the reason for the drainage if the device is off? battery getting old? Device receive nov. 07

 

Windows 10 - Laptop battery drainage while shutdown and unpluged


I upgraded my laptop from Windows 7 to Windows 10 recently. The laptop battery is now draining 20% overnight when the laptop is shutdown and unplugged. With Windows 7 the battery drainage was negligible (even over a week). The laptop is a Lenovo Thinkpad Type 1143-3FU. The Thinkpad has a red light which glows while on. After shutdown it now flashes a few times after shutdown before stopping (rather than just going out) which indicates to me that something is still running, but I do not know what. The laptop battery is good. The computer does not appear to be hibernating because when I start the computer it shows the Lenovo screen first thing. Any suggestions?
