I'm having a weird reoccurring issue with my Lenovo Z50 laptop. Windows 10. I normally keep the power lead plugged in and turn the laptop on on a morning and it starts up with the lenovo logo displaying, but then goes no further unless I take out the power lead. Now however, this doesn't solve the issue and I have to keep turning it on and off until finally it powers up on battery power only. Another problem is that it can't update properly because when it goes to restart, if the AC lead is in it can't turn on properly, and if I take it out, it wont update properly! Panicking it's going to conk out on me! I've not tried removing the battery and replacing yet.. Might try today. Do you think it would help with a new AC lead/battery? Or can it be fixed simply do you think? Thanks!
