I love Microsoft hardware, regardless of what you think of their operating systems it’s hard to argue they make good mice and keyboards. I bought a new mouse yesterday – a Microsoft Laser Mouse 7000 and left it to charge up overnight but this morning I found it hadn’t. The charge light was flashing red, instead of pulsing green (recharging) or solid green (recharged).
A search shows that this model has problems with its supplied battery. I tried the quick fix for the Microsoft laser mouse not recharging, putting a folded piece of paper on top of the battery to make it press on the battery detector, but this didn’t work for me. A new battery, somewhat thicker than the one supplied by Microsoft gave an initial green glow before it too started flashing red.
If you want to know what battery works with the mouse try an Energiser Rechargeable 900mAh. It has a slightly longer positive terminal and slightly larger girth. The mouse is now recharging fine.
