[Kevin Verma]

Hello,

I am continuesly noticing that the battery status being shown as NA
and it is not possible to see the charge remaining via "Gnome battery
charge monitor" while the output from /proc FS  and dmesg are as below
:
--------------------
[root@localhost /]# cat /proc/acpi/battery/BAT0/info
present:                 yes
ERROR: Unable to read battery information

----------------------
Any possible outlook, if there are any bad effects on the hardware
while this problem remains unsolved ?
