who thinks notebook batteries r a waste of time . and if not which have the longest usage time.

Centrino's have the best battery life so far.
Notebooks are not useless at all, they're good for all round computing.

Kee-Lo what is it's battery time?

[tellingd]

The amount of time that the laptop can operate before needing to have its battery recharged. The faster the processor the more power it needs. Also depends on screen size and brightness thereof. Few other things too

Thank you very much Dave but I meant actual time in hours. I was wondering what the battery life was on Centrino laptop. I'm just curious, cos my biggest problem is lack of battery time

Maybe I should turn my brightness down Dave

Sorry I'm not making myself very clear am I. Your talking battery life and I'm talking usage time. I'll shut up now

No apologies necesssary Faith. Centrino chips have more cache memory and therefore can work at slower clock speeds and so use less power. I understand that you can get around 4 hours out of a centrino laptop; although that is with a small-ish screen and of course you will have to pay a premium

2hrs Faith

Faith, my Z1RSP with a 1.7 centrino runs for about 2 1/2 hours on the battery.
If i change the power profile settings for maximum life (slow the processor, reduce the screen brightness, turn off power to both the DVD drive and memory stick, only run easy applications such as Word or Excel) I can then run for up to 4 hours.

There is an optional double sized battery available (at a price !!) which would raise the battery life from 2 1/2 - 4 hours up to 5 - 8 hours.


If computer suppliers ever supplied a screen with a translucent back, we could use ambient light through the case to light trhe screen, thus allowing us to turn the back light off and run the computer for another hour or so.

New screen technology is being worked on with "light emitting polymers" which will do away with back lights for ever!!

Thanks for that Steve you know 4hours would be brilliant for me :smileycool:. I suppose if the translucent backs are new screen technology, they will be very expensive won't they
