Hi all, not often I look in here, as I don't often get any problems with my two (old!) Acer V3 771 Laptops. One I use all the time and I have one for a spare.
On three occasions in recent months, I've had issues with the battery status icon on the taskbar, showing the incorrect amount of charge, or no icon at all. I've eventually managed to sort it on each occasion, but it is becoming a bit of a pain. Last night, it was showing 64% charged, but it had been plugged in all day with no other issues.
I managed to sort it again by deleting the battery & charge drivers in Device manager, removing the battery (not very old) whilst plugged in to the charger (new genuine one), powering off the Laptop and restarting it, replacing the battery and doing another restart.
I did notice that both the Microsoft AC adaptor and the Microsoft ACPI-compliant control method battery drivers are dated 2006 - some 7 years before I purchased this Laptop new in 2013, which is now coming up for 12 years old.
Are there no newer drivers for the V3 771 battery system than these?
I haven't been able to find any, and also wondered if somebody could throw some light on why this problem is happening.
FYI, the Laptop was supplied with Windows 8 which was awful, so I reverted to Windows 7 until the free upgade to Windows 10 was available, and it has been running Win 10 very well since then. It's had numerous upgrades but is still doing everything I ask of it, except for this battery charge reporting error. I know it's old, but I love it dearly and don't want to replace it.
