I have a question for this laptop users, Do you have a problem with drain of battery. When laptop is completely switch off and fully chrged (no speed start option in Windows, no hibernation - just completly swich off) the battery after 2 weeks is about 75 % of full charge.

When I send a laptop to service they inform me that it's absolutely normal :D But they coudn't show me such parameters in technical specifiation.

Do you have such problems?

Do you know maybe have a contact to manager in Taiwan responsible for international service? I can officially complain.

  • Any battery, even if it is not being used, will lose some of its charge! Even if you charge 100% and leave the notebook completely off for a month, the battery will not be at 100%

    Of course I agree it's normal, but come on - it's normal temperature (not cold) and in any other laptops I used it never was done in such speedy way. That means that in about 2 monts it will be drain completely! If you know how modern Li-Ion baterry works you know that it can be damaged if lower to 0%. In my opinion it's definitely wrong with battery or main board of laptop.  

  • Did you verify that it really was shut down without the fast boot and with hibernation and suspension off by pressing alt + f4 and selecting shutdown? If you have done so, do a power reset: unplug the notebook from power, turn the notebook and find the hole in the photo and press the button with a clip for five seconds! Then leave the notebook off for five minutes and then do the same for two weeks with it off and see if the percentage drops (which I think will happen)!

    Of course I shudown latop. When fast boot was on, the drain 75% was in 2-3 days. So first I swich off this function in Windows 10.

    I try it with this hole when laptop comes back but this is only a "hard reset" I think and I am afraid not help.

    PS:

    The funniest think was service test: they turn the hiberantion on (!) and the laptop was not working for 2 weeks and they said that drain is normal. Of course if hibernation statte - laptop can drain the battery :). I am tottaly agree with them. 

    And this is why I am so angry - they probably cannot find the problem and want to cheat me. I'm probably going to take them to court.

    Unfortunaltelly you can have this problem in laptop but never find it if works every day on it. 

  • You can check if a bios firmware update solves this problem! For those who do the battery charge control is the bios! Make sure upgrading the firmware resolves, but do it with caution as this procedure is risky and should be done with the battery fully charged and the notebook connected to power! Then turn off the wifi and unplug the peripherals from the usb ports before updating the bios!

    A new BIOS from 2018/07/24 is not in the laptop (probably service not upgraded it to the newest version). But the changes were: Updates Intel microcode, ME revision and KBC version. The power optimization change in BIOS was in 2017/12/21. I cannot check this what the version is on the laptop. But speaking truly that's the service problem, not mine to check if the problem is because of the microcode in BIOS, don't you think?
  • To check which version is installed on your laptop, go to cmd as administrator and type wmic bios get smbiosbiosversion! I'm not sure if a bios update will stop unloading your battery! However it is this firmware that manages it and therefore, it may solve the problem!
