laptop shots downs my monitor

[fakan]

hello guys

I have a little problem. Every time I'm leavin my laptop on (downloading something or just leave it idle), when I come back later on the screen is black and doesnt react when I move with the mouse or press any key on my keyboard.

I set up the lid so it doesnt go to stand-by or anything like that hmmm if I leave it closed for short period of time when I open it up .. comes back no problem but after few hours sometimes 20 minutes .. the screen is black but still the music of the net is playing and everything.

its inspiron 5150 3.06 GHZ P4 512 ram WIN XP PRO + ALL UPDATES

the thing is that it cant go to sleep when I'm downloading 15 files and its playin music at the same time.

Thats why I went to settings and set the option "when I close the lid" - " do nothing"

so it should be running no problem.

when I dont close the lid its ok and never does that but when I close it and come back after some time its playing the music and still downloading the files but the screen is black

any ideas ?

the laptop came with XP home, I formated the hd and installed brand new install of XP PRO hmm I hope thats not the issue cause its running great with out any problems .. except that black screen

I have all windows updates and just updated bios and chipset

yeah all the power saving utilities r in the laptop. There are 2 options of settings
1: if the laptop is pluged in the electrical outlet / the monitor + screen saver n all those settings r set on max

2: if the laptop is on battery power / screen saver + monitor off n sleep mode kicks in sooner.

device manager shows everything installed as well as the dell support website

so the laptop is hooked on electrical outlet and "closed lid" option is set to " do nothing "

it shouldnt even go to sleep I think ...

I hope I make at least half of the sence like u did

I am not familiar with your laptops BIOS setup..but some BIOSes have settings for system sleep etc. I would go into the BIOS and look for anything that could make it sleep or blank the monitor.
