Re: Laptop Battery Problem

I suspect that the battery has died on my HP/Compaq Business Notebook
NX9005.

For a while, the battery status light has sometimes been green (indicating
ok) and sometimes flashing amber (indicating a battery problem). Now, it's
on solid amber (indicating charging) but the icon in the system tray never
gets beyond 0% remaining - even when left to charge up over night, with
the
PC off.

If I turn off the AC adapter, the PC stops dead. The battery itself has a
'fuel gauge' on the side - a row of LEDs to indicate various states of
charge when a button in pressed. None of them light up!

My guess is that the battery is dead, and all will be well if I buy a new
one. However, I have a slight concern that there might be a charging
system
fault which is preventing an otherwise good battery from charging - and
that
I might end up spending a not-inconsiderable sum on a new battery to no
avail.

Is this possible, or am I worrying unnecessarily? [The PC does work
perfectly ok off the AC adaptor, but not off the battery]. Is there any
way - short of buying a new battery - to make sure that it really is the
battery at fault?

[I've just noticed another thread in which it is being suggested that dead
batteries can be revived by putting them in a freezer for a while. Is this
for real and, if so, what is the technical explanation for it?]

This sounds exactly like a dead battery. The charging circuit has detected
that the battery is discharged below the minimum limit and has (correctly)
refused to charge the battery. There is no method of recovering the battery
and indeed, it is extremely dangerous to try.
