Laptop battery life.

  Nimblefingers 09:44 15 Feb 2005

I recently purchased a new Gericom Ego laptop with Centrino Technology which is supposed to have a battery life of over 6 hours when fully charged. This was one of the main reasons that I purchased this model.
I now find that, after charging, the highest battery life available is 3 hours.
I have tried using the battery until it is completely empty and then charging for a full 24 hours. I then hold the mouse over the battery icon and it say's that the battery is 100% charged with 3hrs lifetime in brackets.
A phone call to the Gericom helpline brought the response that I would have to reduce the CPU speed to increase the battery life to 6 hours.
Is this correct?. If so, how do I do it? Or was their claim of 6 hours battery life inaccurate?
What is the point of having a fast processor if it is necessary to reduce the speed to maximise the life of the battery?
Thanks Pat.

A battery life of 6 hours is probably only possible if the machine is switched on but idle. If you made the point, probably in writing, at the time of purchase that the fundamental reason you bought it was the claim of 6 hours battery life, you may have a case for return.

Aaahh marketing men!

I think that you will find the 6 hours is based on idle mode, similar to mobile phones tests. Batteries are a very funny product, depending on type of product and manufacturing process.Going from the old lead acids to what is available nowadays, is a whole different ballgame.

Find out the manufacturer of the battery, and see what information they have available. Here is a supplier who could perhaps help click here

I would like to write to Gericom but cannot find an address for them anywhere. Does anyone have their address please?

Laptops fitted with mobile versions of processors are designed to run the processor much more slowly when on battery power to conserve battery life. Some are dynamically controlled so that the processor speed will react to the computing load.

You can extend battery life by adjusting the power options.

Go into Control Panel - Power Options and under Settings set the Turn off monitor and Turn off hard disks to whatever figure you wish.

You should also note that to get any significant battery life you should switch off the wireless adapter.

You may find this utility to be useful: click here You can use it to change the processor speed and override the defaults.

I am typing this on an Ego in my living room, wirelessly connected through my router upstairs. It is a very good machine, let down by a very unresponsive keyboard.

Running suse 9.2 on my laptop, the processor cuts down from 1500 mhz (Centrino) to 600mhz when there is only a light load. This gives me 4 hours and 20 minutes - when all I do is type on

Your machine should have something like speedstep enabled.
