I recently purchased a Lenovo IdeaPad Y400 and have noticed that after I do the following:
- Use the laptop while plugged in
- Shut down and unplug (it is fully charged at this point)
- Turn it back on after a couple of days (between 5-6) - the battery indicator tells me that it is now around 60%
I realise that all batteries discharges even when not used but ~40% in less then a week seems a little excessive to me. Is this normal behaviour?
Note that the usual things like LAN wake-up and always-on USB are all turned off in BIOS/don't exist.
