Ryobi 40 Volt Battery - Reflash Fix

I'm hearing that the 2.4 Ah and 5 Ah batteries have an internal memory chip counter with a software bug. There is an int variable that should be a bigint. The battery stops working because of an overflow bug. Ryobi has found the bug and can reflash the battery. If the battery has sat too long the cells might be physically damaged and they can't reflash it so don't wait.

Random USB Mouse disconnect sounds

My beloved Dell desktop kept making random Device Disconnect system sounds - but not Device Connect sounds.    It seemed to happen mostly when I move my mouse over windows which were rendering heavy graphics, ie. a webpage.

I got annoyed with the system sound happening several times per hour.  Fortunately a program called USBDeview helped prove it was my mouse disconnecting as the "Created Date" kept updating when I heard the sound even though my mouse moved and didn't miss a beat.  So time for a new mouse.

I don't know why there was no Connect sound or how the "Last Plug/Unplug Date" didn't also update since my mouse kept working.   Regardless, USBDeview is a good tool for your toolbox.
