Hello Artemis,

My name is ArmyMason and I think I can help you with this. Their is two different ways of getting around this issue. One is turning up the back light via your keyboard. Their should be a blue picture of a sun with an arrow pointing up, mine is on the F10 key. Hold down the FN key and tap the up sun key until you get the desired brightness. The other solution is take the computer out of laptop mode. You can do this by right clicking on your desktop and choose properties. Click the Screen saver tab and then click the Power Button. Change the power scheme to Home/Office Desk and click Apply. Now when you are on battery power your computer sceen shouldn't dim and your processor should also run at full speed if you choosed to do the second option.

Screen is dim when power not plugged in

In power settings you will find the dim adjust, Your laptop has power settings you can adjust to your preference. That said, the default settings are usually set to a power saving that means when you unplug your laptop from th AC source your laptop will dim to the power savings settings and prolong battery life. Look in power settings by right clicking the power icon in the taskbar notification area and open the power options. There are many options to choose from I use High Preformance, but on battery it shorten battery life. If you need assistance just respond to this solution.

Hp pavilion g series laptop screen automatically dims.

g what?; there are many G series, please tell what you have there.
the bottom of the laptop has service tag with full model there.
like G61-1234us. ))1234 is a made up # fake, but yours has one.
NO OS stated, windows what XP, Vista, 7/8/10?
the PC made before 2010 (see why I ask what you own)
has CCFL lamps that all go bad before now mostly.
like ..G60 ,G61, G70
all those have CCFL, up to 2010 and LED back lamps began.

the brightness works only if the HP drivers for you PC are there.
drivers must match
  1. PC model
  2. and OS
  3. and what graphic chip option it had. day 1.
a 3 way match ! or it fails.

the other DIM out deal, is if the PC thinks it lost AC power.
and is running on battery to save battery life (longer)
all do that, every one made unless turned off
here is the test.

take out that old main battery, leave it out, they dont last this long so, out it comes or it will messup an PC.
if the battery shorts it will confuse a laptop big time.
then run on AC power only.

does the screen now go full bright?
in device manager (from control panel)
are all drivers there ok, on that screen?
Graphics driver?

next time at least tell the service tag information
so the helper can actually help.
we be blind see?

My g60 -235dx laptop on startup error message say communication problem with I/O deveice, HD, flash drave , CD-ROM

G60-235dx. (2011 model, is my guess)
ok tell the full story please.
PC boots sequentially.
progress in that matters. so it seem windows unstated runs?
so you power on and what happens ?,
errors before windows logs in or after.?

my guess #1 is the main laptop battery is bad, remove it.
this pC runs on AC power pack endlessly, (AC power good)
dim screens. can be bad CCFL lamps or low power in the PC.
so again take out the battery
what flash drive, remove that, test the pC with no usb devices at all plugged in.

just an A.C power pack and no main big battery.
this PC has old CCFL lamp tubes that all go dim, fast.
turn yellow then dim the flicker and then DIE for ever.
all do. some in 2 years time never turned off. they do.

it the screen goes black use a flashlight if data is good on the screen the back lamp is croaking. (***** of CCFL tubes)
there are many cause of black screens, I can list 30. (will not)
but dim screens are only
1; main battery bad and shorted.
2: AC power pack near dead. (weak happens)
3: shorts in the main board, modules.overloading power buses.
4: CCFL dim as every one this old does, all do.
see flash light test.

Is there a quick way to dim my screen to save on battery power?

there should be a Fn key that looks like a little sun. One with an arrow up and one with an arrow down. Just hold the Fn key and press the key with the arrow down and it should dim the screen.

Delll axim x30 screen remains dimmed even though fully charged

ok , you have checked the brightness settings, check battery power settings as well. you may have to do a hard reset so back up your info. If doing a hard reset, pull the battery and charge it on its own if you have a cradle. Hope this works for you

Display brightness

Ok on your keyboard there should be some way to adjust the brightness just plug in the laptop and adjust it to what you want then unplug the laptop and adjust it to what you want and it should keep that setting. if that does not work you can check the bios settings some laptop bios' have a brightness option.

Screen is dim

Try looking for a function key (usually used by holding down the Fn key and then pressing one of the "F" key at the top) the key will be marked with a brightness indicator.

Is your screen only dim when running off the battery is it dim when running when the charger is plugged in as well. If it is only dim when the laptop is running on battery then this may be caused by a setting in Power Options which is located in Control Panel (that is if your running Windows). In Power Options look for settings about running on AC Power and running on Battery power.
