Hi There!
My NEC MP 900C has some serious power management issues.
In a previous post I mentioned that it gives the 'main battery is dangerously low' error even on a full charge when the unit is plugged in. The battery itself wasn't prematurely drained, and will operate as normal despite the warnings that the OS is giving me.
NOW the unit gives the warning that the backup battery is drained or missing. I replaced the backup battery, this kept the unit happy for about 3 days (at which time the backup battery was never used to power the unit), it gives the warning constantly now, as it if does not recognize the battery.
If any of you have tried running a MP without the backup battery, the system responsiveness slows to a crawl, to the point where typing on the keyboard takes the unit forever to respond. I checked the contacts, both are connecting with the new backup battery.
This issue has pretty much bricked the unit... I'm wondering if this is an OS problem.. seeing as usedhandhelds charges $150 to fix a unit that only cost me $200, this sucker is about to go in the trash unless there is some way I can repair it myself...
er, without backup battery, the 900c runs the same, it doesn't slow down.
apparently you have a hardware fault then, unless you haven't tried hard reset yet. remove all batteries, then put back, then it should ask you to calibrate the screen, then it was hardreset.
don't throw it in the trash though - see, people are interested!
(so am I
)
by the way if all you want is to make the battery warnings disappear - I can give you an explorer.mui for this
which OS version are you running? so i can give you the right version.
