So my year and a half with the Yoga Pro 3 there have been some problems.
The latest concern to crop up is that the battery on my Yoga 3 Pro would suddenly discharge for no reason. A typical scenario would be I would shut it down with around 60% power still being reported. When I would come back to it 2 hours later, I wouldn’t be able to power it up anymore as the battery was reporting as completely drained.
When I would try to charge the laptop there were times when it wouldn’t charge, even though I kept it plugged in for more than an hour.
Finally I searched online and found a Lenovo forum which had some answers. Unfortunately Lenovo, based on the irate posters, has not done a good job of finding a solution and communicating some easy to do maintenance steps which may solve the problem.
Fortunately internet posters may complain but some are resourceful and two of them, MarinM and Vladtech, came up with solutions they shared. (All steps copied directly from the forum.)
Unplug AC adapter
Open OneKey Optimizer
Choose Save Power, from top row of icons
Choose Battery Conservation, from the row below the icons (Checking Power Ultra Saving Battery Conservation)
Click the Battery Sleep Mode slider to turn it on (blue)
Shut down computer
Insert AC adapter
Turn on computer (this automatically resets the battery sleep mode to off)
01. Uninstalled battery driver from Task Manager
02. Disconnected AC power
03. Unscrew 10 bolts of back cover and remove cover. As you know YOGA 3 PRO have not battery slot, that why u need anscrew back cover to reach battery
04. Carefuly disconnect battery jack. Very easy to find because only 2 black wires going from battery.
05. Connect battery jack back
06. Plug in AC power
07. Check that battery start charging. This is up to you, but I just start the Laptop with open back cover, good thing that screen can flip.
08. Confirmed that battery charging, OKO gives 3.5 hours from 0%
09. After 2 hours, battery has reach 95%
10. Switch off AC power, disconnect power cord and close back cover. Feeling satisfaction. With myself of course not with LENOVO support.
I tried MarinM’s solution and it worked brilliantly for me. My Yoga 3 Pro is now running normally again. (Although oddly now every time I turn it on it reports more power than when I last powered it off. So if I turn it off with 70% power, the next time I turn it back on it reports 74% power.)
For good measure after I trued MarinM’s solution I also ran the battery calibrate feature of the One Key Optimization software. The calibration took a long time (over an hour) and then finally just reported that it failed and to try again. So honestly I’m not sure if the calibration helped in any way.
The Yoga 3 Pro is certainly a finicky beast. Still, I’ve found it very useful and don’t regret including it in the list of my favorite things of 2015.
