Call the supplier and ask for an exchange. From memory those battery packs had some small circuit board in them to assist with the "fuel level." Battery rebuilders found out that circuit was optional and the laptop would still charge and run without the "extra" circuit.
Sorry I can't remember more from those days.
This question concerns
IBM Thinkpad 760L
855Mb Hard disk drive
Floppy disk drive
PC-DOS Version 7.0 / Windows 3.1
I installed a new battery on this notebook today and when I go into the "Fuel" window in the desktop it states "no battery pack detected".
Nor am I getting a battery indicater in the small LCD window at the top of the keyboard that thinkpads of this era possess. The old battery was recognized by both of these features (it was not holding a charge for more than a couple of hours hence the replacement.
The new battery came completely shrinkwrapped and the part number is listed as compatable on the IBM website.
I appreciate that these batteries usually come in need of a charge (usually 12 hours overnight to begin with) and that capacity increasses with charging / discharging.
However even if it is completely discharged I would expect it to be recognised.
I have checked that it is installed correctly and pressed firmly into place.
Any ideas would be welcomed - although I consider myself an advanced user of PCs in general I am something of a newcomer to the world of laptop computer hardware, therefore I am concerned I may be missing something obvious that is well known to regular users of laptops / notebooks.
