I have an HP n5415 running Windows xp HOME. Just recently the screen on the laptop would just go black, with no warning or error. The laptop does not turn off I can HEAR and see that the HARDDRIVE is doing its thing, the lights are still on, I can OPEN the cd drive, etc. I have tried to hook it up to the desktop monitor and it does the same thing. I can not run any anti virus software because it goes black to quickly. Anyone have any thoughts? Thanks BillDoes the screen malfunction before windows loads?
If you go into BIOS, does it do the same thing?Some times I see the windows logo, other times is does not get that far. I can get into the bios sometimes and it has gone black while I was in it.Have you checked your power saving options in BIOS?No how do I do that? All BIOS screens are DIFFERENT. You use the arrow keys to navigate through the various menus. Your BIOS might look something like this:


Notice the Power Management option?

Or maybe it looks more like this:


Do you see the Power option at the top of the screen?
Find this in your BIOS and disable sleep mode. It may say something confusing like S1 or S3 mode. Just disable the power saving options and see if that helps you at all.I look in the bios under the power tab. There were two things listed.
1. enable/disable docking options
2. speed steps ?
Nothing anywhere said anything about sleep mode.Anyone else have some thoughts or ideas that may help me? Thanks for your time. Bill Quote from: GotWoodzy on January 08, 2009, 09:06:46 PM
