battery life dramatically reduced

Thanks actionparsnip, that solved my question.

Battery life depends on numerous factors:
1) age of the battery
2) how often you recharge it before it's discharged
3) whether you let it completely recharge before unplugging it and using the battery
4) what peripherals you have and their drain on the battery
5) number of apps you're running at the same time
6) what changes you've made to your system
7) the list goes on

I'm getting longer better life with 10.04 than I did with Windoze 7.

Well, luck you marcus aurelius.

Unfortunately this doesn't answer the question.

just becasue you're battery isn't lasting 4-6 hours as when you initially bought it your laptop, doesn't mean ubuntu is the cause of it.

you need an attitude adjustment.

Normally upgrading Ubutu reduces power consumption a little more... at least on my computer it always does.

Perhaps the CPU is running faster or getting more work than it should.
 - Is some speedstep daemon like powernowd installed on your system?
 - If you do a
 watch cat /proc/cpuinfo
 - does the Megahertz number displayed there get smaller if nobody uses the CPU?
 - start gtop or top from a terminal and see if there are CPU-hungry background processes running. And if yes - if they belong to packages you need.
 - If you leave alone your system for 5 minutes - what does
  cat /proc/loadavg
   output?

Perhaps it is the graphics chipset:
 - Try to disable desktop effects in System/preferences/appearance

Other possible reasons:
- laptop-detect isn't installed

...Or klick on the gnome-power-manager-icon, and see if you can activate the "spin down the hard disk if possible" is checked there.

I am aware of all the issues you listed, and have tried running the
laptop with minimal loading.

The laptop was working fine - good battery life until I upgraded to
Karmic then Lucid, so I know Ubuntu isn't the problem.

With regard to the age of the battery I bought a new one and there was
no change in the battery life.

I suspect that this is a problem with the Samsung laptop, but as the
drop was so dramatic 4+hours to 2- it felt to me as though there is
likely to be a problem rather than just a minor performance change
between releases.
