Try this -- it is called a Power Drain Procedure -- HP technical support helped me with this --
1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.

Prostart 6 button in sleep mode


Sleep mode is a convenient power-saving feature used on both laptops and desktop computers. This feature powers down hard disks, monitors, wireless devices and any other power-consuming peripherals without turning the unit completely off and necessitating a reboot. Sleep mode can prevent battery drain if using a laptop or mobile device while away from the power supply. This mode is useful when quick access to a computer is needed, but can be irritating if the sleep mode takes a long time to come back from. It is simple to turn sleep mode off, based on the operating system being used.

Go to the "Start" button, then click on "Control Panel." In the control panel screen, click "System and Maintenance," then click on "Power Options." This brings you to the "Select a power plan" page. From the "Select a power plan" page, select the option that says "Change plan settings." This changes the settings on the currently selected plan. Select the "Change advanced power settings" option. Click "Sleep" and then click on "Sleep After" to expand it. If using a laptop or mobile PC, click "On battery" and "Plugged in," then select the "Never" option. This turns off sleep mode for both battery and AC use. If you are using a desktop computer, click "Setting," click the arrow and then click "Never" to turn off sleep mode. Click "OK," then click "Save changes" to save the modification. b> Turning Off Sleep Mode - Mac OS b> Click on the Apple logo at the upper left corner of the screen to open the menu and select the "System Preferences" option. From the "System Preferences" screen, click on "Energy Saver." If you are using a desktop, select "Power Adapter" in the top drop-down menu. In the second drop-down menu, select "Custom." Highlight the "Sleep" tab, then adjust the top slider to the far right, marked "Never." I f you wish the display to stay on, adjust the bottom slider to "Never." Click the red button on the upper left side of the "Energy Saver" screen. If you are using a mobile product or laptop, follow step 2 and select "Battery" from the top drop-down menu. Repeat step 3 to change the settings for battery use. Hope this helps.

HP Touchsmart IQ526- Black Screen and Amber LED please help! No display. Is this a hard drive issue?


Also had this issue on the Touchsmart IQ526. Removed the CMOS battery, waited some minutes, then powered on. The power button remained blue and had video again. Reinserted the CMOS battery and put the unit back together. Note - the battery was on the mainboard.

I have a Dell Optiplex 780 and when I am logged in and walk away for 15 or more minutes it will go to sleep, I will then come back wake it up, log in and the screen will go black and I cannot get in unless...


This problem is ongoing because you have it configured to sleep turn the sleep mode off. What it is doing is attempting to load drivers again and not saving to cache when in sleep mode you may have not enough storage allotted for the sleep mode to save information go and increase the storage memory to store the data so that when it sleeps it can store the data and wake up with your screen as it was when you left it.
Personally I do not use sleep mode never have, never will. It is nothing but a problem for me anyway. I always keep my machines running with the exception of a lap top. So my suggestion is turn sleep mode off. I also log out and then log back in same principal really. Or just close the machine totally power it down. Sleep mode was a wonderful concept along with shutting down hard discs etc. However you will often times be more into a hassle than just leaving it on or shutting it down. Less work for a computer is better just my humble opinion.
Last but not least, my last resort would be to re-install operating system again once I start getting to many things going wrong with my machines I do them over solving all sorts of problems that are behind the scenes that take hours sometimes to repair individually. This would be after you retrieve your lost files from the drive. John

I am unable to access the internet from sleep mode Can only get on internet from shut down mode


Three possible causes of sleep mode. first, an extensive screensaver with password lock prevents display. A condition that is observable as a blankscreen also known as sleep mode. Second, a computer power saver settings that shutsdown during idleness. Third, An improper shut down of the computer would have caused a sleep mode to save the system data files.



Restoring the computer to regular functionalioty

First solving predictable sleep mode settings
1. A movement of mouse pointer across the screen should reestablish unprotected password modes
a. password protected sleep mode would display an promp message requiring key code soon after the mouse pointer has changed direction

sloving unpredictable sleep mode settings
1.A computer power saver, screen saver, or splash screen displays prevnting programs acess would require manually powering off the computer system.
a. A manual power back on of the system should restore to program functionality mode

important notes
1. contact expert technical assistance
