Laptop screen question

9 years ago

I have been recently using a temporary loaner HP Elitebook 8440p with W7 that does something odd. I am not saying that it is a "problem", rather something I do not know if it is a problem. I went to the web and got the user manual. I downloaded it, looked around and did not see this mentioned so maybe someone will have an AHA! moment when reading this.

When I close the lid/screen, the screen goes dark and I cannot "light up" the screen back 'on' except by hitting the power button and rebooting. If I do that, the laptop reboots and the screen is fine. I have closed the lid slowly to determine exactly when this occurs and noticed that the screen goes dark as I am close to completely closing the lid (or about an angle of less than 30 degrees).

By the way, Ctrl-Alt-Delete does not help. Neither does pressing the Power Button "slightly".

I considered that this "behavior" was some weird power saving mode feature but who knows. If it were, I am puzzled why make it so difficult for one to stop the power saving mode. Then again, maybe I am reading the wrong chapters of the manual; I just have not found it. The person who loaned it to me has not replied to my emails so maybe someone here has some ideas.

TIA and Merry Christmas everyone,
Luis

goes into sleep mode ... is normal for a laptop when you close the screen ...

hitting any key or a mouse wiggle usually wakes it.. pushing the power button is also a normal way to wake it.
Sounds like it doesn't wake properly.. some program maybe interferes .. a snafu.

Right click you little battery/ac power icon in the system tray, click on power options maybe... look around. Not your laptop maybe just change it to hibernate when lid is closed.

On Windows 7 you can change what happens when you close the lid in Power Options as Mikie mentioned.

I chose to do nothing, but that's simply what I prefer.

Thanks, pkponder! I called Toshiba as you advised and was told that the hardware was covered for 1 year. I have to find the receipt and then contact the warranty department on Monday to make arrangements to send it in to Toshiba. Thanks again.

Toshiba Fn plus the up/down keys adjusts system volume sound levels. Fn plus function keys F5&F6 has little pictures of suns on them here and does the display brightness. But I think to make it the light level stick you have to use the Control Panel 'Power Options' ... at least on my Toshiba is the way it seems to work.

Yes, that is a good video for resolving such an issue....with one major exception. When a person is going to work on a computer, they would be wise to turn the computer off before doing anything to the computer. If it is a desktop, turn it off and then unplug from the wall outlet before making a repair. If it is a laptop, turn it off and remove the battery. When repairs are completed on the desktop, plug back into the wall outlet and then turn the computer on. When repairs are completed on the laptop, re-install the battery and then turn the computer back on. For some people this may seem like elementary information, but for others this information is not known. I would say that if that young man in the video works on his computer enough times with the power on, he will probably experience ESD (ElectroStatic Discharge) and will be headed to the store to purchase a new motherboard.

Laptop won't pass starting window screen

Thank you so much for all of your inputs. I took out the battery as suggested, it did not work. Powered on with/without docking station, it did not work. Went to work called the IT support team. First tried the "tapping F8 key" just as Mikie suggested, got into Start Options menu, picked "Last use good configuration" or something like that. Once computer finished the steps, repowered it on, but the power up still could not pass the "starting window" screen. Then tried the "tapping F12 key". I had to start tapping the F12 key as soon as push the power on botton. Finally get into the start options menu, picked "diagnostic". It ran a lengthy testing for about 30 minutes. The results showed error code 2000-0142, msg 6142 status 79. Tech support person said the hard drive was bad. The rest of the testing on memory and CPU...etc. showed no problem. I am waiting for IT to install new hard drive and port old data. I only hope that the data I did not back up would be preserved.
