Thank you Jim. I will try that. Kerry -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James Aldrich Sent: Tuesday, 11 October 2005 3:05 PM To: Braillenote List Subject: RE: [Braillenote] battery calibration
Hi Kerry, No problem at all. A couple of thoughts though! If you plug in your M-power and after two hours it only shows 90 to 96 percent, unplug the AC adapter and plug it in again. Leave it plugged in till your unit reaches a hundrede percent even when the unit is unplugged. After a time, you will probably get a battery low message. If you do, get out of what you are doing and plug in your BN. It is a good idea to be at 8 to 10 percent when you plug in your BN. When the battery in my unit gave me the battery low message at ten percent, I plugged it in immediately. It said battery low, then AC adapter on. I checked it three hours later and it was at a hundred percent. I was busy with other things otherwise I would have unplugged it at two hours. It doesn't matter much how long it is plugged in, it matters that the tgage reaches a hundred percent. My unit has been charging consistently like this for some while now. Do take care!
