Try running a penny across the monitor's cable pins while powered on. If you contact a certain pin with the penny and the monitor exits sleep mode, your monitor is fine. If not, buy another one.

Keyboard and mouse not working and monitor going to sleep

HP Pavilion Slimline S3400f Desktop.
dont worry ALL PC end up like this,, all do.. sooner or later..
NO OS stated, XP"? never post without OS stated, or answer get 10x more harder, See? make it easy for the helper and get more help.....
no Monitor stated. (maker, CRT, LCD what?)
The monitor is not fibbing to you BTW, the PC did go dead or to sleep. seems its monitor monitor of some kind with DVI.

if the monitor works on other PCs then the monitor is not bad.
i Bet it works (old ones 2002, have a hidden deep internal sleep mode. and is not yours IM sure now) DVI IS THE ONLY CLUE THERE.
So PC is dead. this PC came with only VISTA new,
is it still VISTA?????????
HP has support on it still
here (carbon dated by me 2008, IIRC)

this year,? get all those files and books there backed up
when HP support ends after 10 year rule, (be savvy?)

what keyboard USB or wireless keyboard mouse
use wired USB keyboards if wireless the battery is dead. easy no?

now in VISTA, go to Control panel, click power
turn off all sleep modes and all hibernate modes
the turn off screen savers, if turned on , disktop . RC right click
in display settings or personalize, turn off , need login to come out of sleep or screen saver.
try a real keyboard, that has USB cable yet? be first thing to do.
always keep a real keyboard, handy,,,
batteries fail. in all wireless devices like this (inside them)

luck you desktops have lies DIM fails. there are many.

one other way , and common is PC overheated.
all do that.
ever one not cleaned out every year,.

#1 all time cause of overheat and PC shuts down.

I have a hp pavillion a710n that will not turn on since i had a power outtage a few days ago and i was wondering if there is a way i can fix this problem

Check your power strip, if you had one. There may have been a reset tripped on it. Short of that, if know for certain that you have power to the machine and it still does not turn on, you likely need a new power supply.

After a power outage my hp a710n won't respond or restart. a small flashing green light on the back of the hard drive is visible. what can i do?

You hear no sounds correct?

In the best of all worlds, your power supply is dead. That will cost around $50 to replace. If there was a power surge that hit the mother board, you are likely to have a fairly expensive repair.

If you have any sounds from the machine, please report them.

Dell E152FP monitor after startup or coming back from standby the screen will show up and 5 seconds later it disappears. I turn off the monitor and turn it back on. The image comes back again but it...


Probably the monitor. LCD monitors use electrolytic capactors which change value with heat. The power board in yours probably has 6 to 8 caps whic need replacement. Take it to a reputable repair person or check out my websit.

My hp pavilion f70 flat panel lcd monitor comes on and works fine with a beautiful picture...for about 1/3 of a second. then it goes blank. any ideas how i can fix this or what might be wrong?

The symptoms you describe, pretty much diagnose a failed High Voltage power supply board problem in the monitor. This is usually cost prohibitive to repair, as LCD monitor prices have dropped a bit, so your monitor is beyond economical repair.

Blank Screen on HP Laptop

HP has identified a issue with the DV6000Z and monitor. I just reported the same problem to HP and even though off warranty, they will fix free. Power up of DV6000Z you will get 3 beeps and no monitor display. External monitor does not work either. This is a known issue woth the DV6000Z.
