Just got a new hp/compaq laptop and I'm amazed by the drop in display
brightness when it goes to battery - ie, when you pull the power lead out.
My old Thinkpad used to drop - to, I guess, 60 or 70%, but this one seems to
drop down to 25% or something. Really dim. Is this normal? Have I got a dud?
Or am I being really dumb in not knowing what to do about it? I've tried the
Help section and got nowhere. I've tried the display and power sections with
no success. Am I missing something obvious? Or might I have bought a pup?
All advice much appreciated.

You don't specify a model, but my HP OmniBook vt6200 remembers
*seperate* brightness settings for on-power and on-battery.
I just tried this while I was on power: Increase brightness to maximum
(fn+f2), unplug power -> brightness drops considerably (to the
*remembered* on-battery level), increase brighness *again* (i.e. now
while on-battery), brightness is as bright as the maximum on-power
brighness.
Many thanks for your response - much appreciated. I don't suppose you know
any way to reset the 'remembered' settings? My old computer had a ac/battery
'brightness ratio' of perhaps 100/75 - if I could duplicate that on the new
one, that would be ideal (I don't need the thing to run at full brightness
on battery...just usable brightness.)
Thanks again.

Just set the brightness the way you like it and it will be remembered.
I.e. run on (mains) power -> set brightness, then run on battery and set
brightness. These two (on-power/on-battery) brightness settings will be
remembered. I.e. there is no difference between "reset" and "set".
"reset" is just set it to what you want.

Many thanks Frank. I guess now the real Homer question: how do I 'set
brightness'? I've been trying to find this in the help, display, power,
screensaver and god knows what other sections...but without success. (I'm on
XP, by the way - sorry, should've said.) Thanks again. Alan.

I'm not familiar with your model of HP, but the motherboard BIOS is where the
screen brightness gets set for most notebook computers. There are two
settings, one for brightness when running on battery and one when running on
line power.
You would think that there would be something in the Control Panel Power or
Display settings, but there is not for good reason. Screen brightness is not
exactly a standardized feature in the design of the BIOS, so the notebook
manufacturer would have to provide a custom driver to control brightness. Most
of them do not want to spend the money to develop and support a Windows driver.

Interesting....sounds to me like someone at HP ******* up. As a default, I'd
guess they should set this ratio at perhaps 100/75 (AC/batt); mine's more
like 100/25. Sounds like the BIOS needs resetting; not a job I'm keen to
take on with a brand new machine...
Thanks for your help - much appreciated.

Have you tried adjusting the brightness from the keyboard?
I've tried - I was recommended Fn+f2 - nada. (Needless to say the thing came
only with a 'Getting Started' guide - 'bout as much meat as a vegans'
convention...)

You don't say what model you have - that would be useful.
On my notebook Fn+f7 and Fn+f8 are the brightness. Fn+f2 is the printer.
Display dims to 25% on battery - faulty? 
Linear Mode
