Re: HP mx 70 Monitor
This is a problem usually with the Power Supply unit inside the Monitor. Often it is the Electrolytic Capacitors arround the Heatsink area. They dry out and go faulty.. It is generally a job for the "Shop" I get them all the time... But in saying that intermittent faults are the hardest to find.. If you do take it to a shop, ensure you get a firm "Quote" and explanation B4 proceeding.

Take out the battery and make sure that it is all the way off. Restart it after 5 minutes. See if it does it again. If it does try holding down the power button for ten seconds and see if it shuts down alll the way
1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.
Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.
Remove the cable. Keep pressing F8 while you power on the system and choose safe mode, press enter. Screen will roll up a few pages and stops for a while. wait a few minutes. windows will start in safe mode Scan for viruses. Restart. It is a virus problem
Disconnect completely computer and display form power cable for ten minutes, plug them back and restart ().This is called hard reset. If you still have the problem try checking the display video cable, both in the monitor and computer socket. If it still does not work connect PC to a different monitor, just to test that is not the pc or the video card the problem. If it still does not work the blackout may have caused a short in your monitor or a system failure on pg then get back here and post the new problem.
