Microsoft has removed this feature because the time left meter is not accurate. In the post Power meter missing remaining battery time, UserBatteryDischargeEstimator which is nearly impossible to find with google and it exists only on the SP4.Īre there any Surface Book 2 out there that show that estimated time, so a UEFI issue could be ruled out?Īny ideas or docs that may help with that issue?ģrd party apps and disabling modern/connected standby are not an option, as I want to understand the root cause why it works with the SPro4 but not with SBook2 Obviously there are some (HP) Laptops that can bring back the information as an BIOS/UEFI option, so it seems to be an ACPI call?īut the Book2 as well as SP4 have no settings in this scope.Īlso the connected standby feature being disabled may bring back some behaviour.Ĭomputer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PowerĪnd I am wondering about the meaning of the entries.Į.g.
Many user say it is missing since 1709 Update. If you google it, there are many opinions. On a Surface Pro 4 it behaves as expected and I try to check the differences. I am examining a new Surface Book 2 and missing the battery time remaining estimation.
