This tab displays battery level as a percentage (since the M631 uses two AA batteries, not a built-in Li-ion). You can also set sleep timers: 1, 5, 10, or 30 minutes of inactivity. There’s a checkbox for “Low battery popup warning at 10%.” The issue: The battery reading is often inaccurate. Fresh alkalines show 95%, not 100%. And the low battery warning sometimes fires at 25%, then disappears. It’s better than nothing, but don’t rely on it. Driver Stability & System Impact (4/5) Surprisingly solid. The driver process ( ApacerM631Svc.exe ) uses 12-18MB of RAM and 0% CPU when idle. No memory leaks, no crashes. It survived multiple sleep/wake cycles and Bluetooth disconnections. When the mouse goes to sleep, the driver reconnects seamlessly. On one occasion after a Windows update, the driver failed to start, but a reinstall fixed it.
