    Oh yeah, do not update to Windows 11, I did it and now I am seriously thinking of downgrading. It*s a pile of **** simply with no advantages whatsoever. You can mostly fix the crippled taskbar and even more crippled start menu, but even after 3 days it's sucking battery like crazy. Even with power save mode every couple minutes windows decides to compute some random crap, index some stuff or whatever. It's minimum 30% less battery life and 5-10° hotter CPU due too all the time it spends going crazy.

    I'm giving it more days but otherwise it's Windows 10 until 2025. 11 right now is a PITA. The only advantage is that they switched on performance mode in edge by default - well and a bit more modern looks not that I would need them... Nothing you cannot have with Widows 10 too right now. I somehow think it must be possible to get 11 to work okay - but so far it just sucks.


    Yes if you upgrade to 11 and had not enabled performance mode in edge, you will see less battery use while surfing with edge. Performance mode really works well and kinda halves the CPU use of edge. Explorer, Windows Desktop Manger, Antimalware Service - constantly doing something. And yeah - currently with Windows browsing with any browser but edge with performance mode on - will suck your battery. With edge and performance mode 11-15 hours are usually possible (with 8 hours of them screen full brightness). If you use Chrome/firefox it will be minimum 2-3 watts more per hour while surfing. The gram doesn't have a high refresh rate display - adaptive refresh rate likely will be windows 11 exclusive - so not backported to 10. So for gaming notebooks with 120-144hz displays - Windows 11 is a must. For everyone else stay the F**k away for now.


    And yes of course I disabled the Windows Insider program right after update and disabled telemetry services and other hogs. I'm more and more thinking of just using Ubuntu and windows in virtual Machine for the programs that I miss. Ubuntu runs great on the Gram and doesn't need constant optimization so power use is staying down.

    BTW - if anyone has access to reset bios easily - to me it seems undervolt is not working via bios settings - but everyone wanting to try:

    setup_var CpuSetup 0x13B 64 (100mv undervolt - 64 in hex = 100 in dec)
    setup_var CpuSetup 0x13D 0x1 (voltage offset minus, default is plus)


    (location taken from the current bios:
    0x7B117 Suppress If {0A 82}
    0x7B119 QuestionId: 0x202 equals value 0x1 {12 06 02 02 01 00}
    0x7B11F Numeric: Core Voltage Offset, VarStoreInfo (VarOffset/VarName): 0x13B, VarStore: 0x3, QuestionId: 0x203, Size: 2, Min: 0x0, Max 0x3E8, Step: 0x1 {07 94 D0 05 D1 05 03 02 03 00 3B 01 10 11 00 00 E8 03 01 00}
    0x7B133 Default: DefaultId: 0x0, Value (16 bit): 0x0 {5B 07 00 00 01 00 00}
    0x7B13A End {29 02}
    0x7B13C One Of: Offset Prefix, VarStoreInfo (VarOffset/VarName): 0x13D, VarStore: 0x3, QuestionId: 0x204, Size: 1, Min: 0x0, Max 0x1, Step: 0x0 {05 91 12 06 26 06 04 02 03 00 3D 01 10 10 00 01 00}
    0x7B14D One Of Option: +, Value (8 bit): 0x0 (default) {09 07 D0 01 30 00 00}
    0x7B154 One Of Option: -, Value (8 bit): 0x1 {09 07 D1 01 00 00 01}
    0x7B15B End One Of {29 02}
    0x7B15D End If {29 02}


    It does not seem to do anything - but if you dare - a value of C8 (200) would if it works surely lead to instabilities - if not outright refusing to boot - hence the need to be able to reset the bios - but I could not find out if this is possible: https://superuser.com/questions/167...ing-the-usinng-the-bios-on-a-lg-gram-computer - here someone complains it is not working so I won't dare setting unsafe values). As I could not find any difference in benchmarks with 100mv undervolt and positive or negative offset - I guess the tiger lake U series simply is not responsive to this setting. tiger lake H this setting would work. A 100mv undervolt should decrease temps by 10% or so and increase battery life by 10%. Sadly it is not working (on H series 80-100mv undervolts seem to be stable, likely the same on U but it isn't possible)

    I bought the white colour Gram 16, it looks stunning in white.

    The colours are coming off quite easily on heavier use. Best would be silver without colour... I think. But white may be better than black because if the colour is removed the difference isn't too big. I filed down the colour on the way edges because it broke a bit then became uncomfortable for my wrist

    Go for it, best laptop in the segment. Excellent screen, keyboard and touchpad. Lots of ports too which is a rarity in premium thin and light laptops nowadays. It is the perfect upgrade from your Samsung Notebook 9.

    There are three colour options: Black, White and Silver. So, you can choose what you like, all of them look good.
