Question about Compaq Deskpro EN 6500+ Model 6400 CDS PC Desktop

1 Answer

NO SCREEN, FROZEN KEYS

My CP turns on, all lights are on, but NO SCREEN. Also, all lights are blue and none turn orange to disable such as the mouse pad and volume. HELP? Was using this an hour before and now all of a sudden nothing! I had a MYBOOK hooked up to it with autoplay enabled. Would that pose a problem?

    Remove the Monitor cable from the back of the tower, and see if it displays the test message. If that is working, then its not a problem with the monitor.

Take out all peripherals connected to computer including AC adapter.
Take out battery.
Press and hold power button for several seconds with all power sources removed. This drains residual power from the system and may correct many problems.
Connect the AC adapter to wall, then computer. Press the power button to start the notebook PC.

This worked for me! There is more info at http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=235992&prodTypeId=321957&prodSeriesId=235992&objectID=c00372748

If the link doesn't help it is at HP website, Troubleshooting, I looked at Compaq Presario v3000 series, and went to boot-up problems...it was pretty far down the page under the heading Other Problems. There is more info if the first part (above) that you do does not work. Hope this is helpful to others!

Having a problem...when I leave my computer for a length of time it returns to the log on screen, but becomes frozen. I can't turn it off from the front button. Must unplug then reboot...this has just...


There are two ways to do it.
1) when the logon screen appears, enter your password (if no, just press enter), you will be back where when you leave.

2) set the screen protection off by: clicking right mouse button on the desktop -> screen protection -->in screen protection box select none --- OK. Then, no logon screen will appear.

Try it.

Emachines laptop e525 mouse pad not working at all so cannot use everything else starting up as normal


Look at the middle cover (above the keyboard). there are two buttons that touch the power switch, the one to the left enables/disables the touchpad. If it shows an orange light it is disabled. Just press it, and be careful not to hit it when turning unit on.

My mouse has stopped working on my acer laptop


Hi,
Do you mean the touchpad or a USB mouse? if its a usb mouse try another usb port, is it wireless? if its wireless check the battery.
if its the touchpad it may be turned off, to turn it on hold down the blue FN button and look at the F1 to F12 keys, one of them has a touchpad icon and it will disable and enable the touch pad, don't worry if your not sure try them all if you wish. You will probably learn something new while your doing it :-)
