<< I don't have a separate charger. The batteries charge in the powerbook itself, right? >> All you need is the combined ac power supply/charger. The 5xx series is perhaps unique in that it has one pair of wires for operating the machine, and another pair of wires for charging the batteries. >> Should the powerbook be off when charging the batteries? >> No, not required. >> Will 2 charge at the same time? >> Yes. Only the right one can have battery diagnostics run against it. That is the principal difference between the left and right battery slots. (The left battery slot can also accommodate a PCMCIA card cage, so that's yet another difference in slots). >> How long should a full charge of one battery take when it's almost empty? >> Difficult to tell, but the batteries do charge in what's called a "fast charge" mode, where the maximum charging rate, consistent with maintaining a certain temperature rise within the battery itself, is maintained. Unlike NiCd batteries, the NiMH batteries in the 5xx series are very difficult to overcharge. >> I think one battery is completely dead. I tried using Emmpathy and another utility, but they don't seem to be able to do anything with the dead battery. Would you suggest leaving only the dead battery in the powerbook for awhile to see if it might charge? >> Probably wouldn't do much unless and until the microcontroller within the battery itself has been successfully reset. >> Will leaving the dead battery in the powerbook while using the good battery cause the good battery to discharge quickly or do any damage to the powerbook or good battery? >> No. >> Also, the screen seems to have some light areas and dark areas. Is this common with passive matrix displays? >> Yes. Adjust the brightness and contrast for minimum shading, consistent with adequate readability. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
