Tecra M11-130 battery not holding power and fan running constantly
Posted: 29-May-2012 17:20

We are having a problem with the battery on one of our laptops. When left for an hour or so the laptop shuts down as the battery runs out of power. We have fitted a new battery but still only get about 1.5 hours.
In addition the fan is running constantly. I have looked at the PC Healthcheck software which shows as follows:
Electric Power
Remaining charge 14%
System power consumption 40%
Battery Health good
Temperature and Fan
CPU temperature 67%
Internal system temperature 56%
Fan speed 88%

I would appreciate any suggestions.

Hi,

Do you have any apps or services hogging the CPU?

Maybe there is something in Task Manager using 90%+ CPU. If not, maybe there is dust buildup in the heatsink or some other cooling problem.

If you turn on eco mode, does that extend the battery to 2+ hours?

1.5 hours is a common value… you should consider that batter working time depends on notebook usage.

The battery would discharge much faster if the CPU would be stressed a lot… in your case something could run in the background wasting the CPU performance and batter power.

Furthermore you said that fan runs constantly… this would discharge the battery too.
Therefore it would be interesting to know what process stresses the CPU.

Start the task manager and check the processes tab. In CPU column you can find the processes which would stress the CPU.

Additionally try to change settings for the CPU performance and cooling activities in Win 7 Power options… this would help to increase the battery performance.
