Computer says it is in save mode

the monitor manual covers this. no model stated by you.
push the monitor front menu button
and find the timer clock for power saver and turn it off.
this is only seen on very old monitors. year 2000 to say 2007
approx.
when PCs started sleeping correctly this feature was removed from inside monitor and now in the PC side, telling the monitor to sleep.
(remote sleep is todays way)

If you are saying it starts and then dies, have you checked fuel pressure again ? Could be the fuel pump relay.

if u r reples this monitor pls. call me dear


tek a new monitor from me same model

I have Dell Inspiron 1520 and I have issue to built in microphone is not working. I tried to execute the Sigma Tel driver from Dell Driver and Support website but prompted 'Exit Error; Error : Device Object not present, Restart system and run setup. Then, asked Dell support to help and they are not really helpful, after System Restore and drivers upload and finally asked to reformat the laptop........

Anyway, this is what works for me.

1) Download the Sigma Tel driver from Dell Support Drivers page and save it in Desktop
2) Shutdown your computer
3) Start your computer and press F8 at the Dell Logo page
4) Select Safe Mode (not others)
5) Proceed to work on Safe Mode
6) Right-click the Sound icon and activate the Sound icon
7) Select Recording device.
8) If still not working, then execute the Sigma Tel driver that saved in desktop

then, shutdown the computer and start as normal, you may see the system able to detect the built in Microphone then.

Hope it will work the same for you too..!!

old post 2017, 1 year old. Desktop and very old monitor.
This old monitor is CCFL and those fail super easy now.
built in 2005, backlamps are mostly dead now.
VGA cable? or DVI#1 or 2 port connected
the monotor told you PC went to sleep mode
I believe it. I bet the monitor works on any other PC you try, I bet.
so put the PC VISTA in into presentation mode.
(like we do with presentations, or kiosk mode, or using a nice DLP projector in theater)
just one app does this below
or learn to use
control panel, + Power settings, and advanced.
turn off all sleep modes,all hibernate modes.
turn on all wake-on modes, for sure USB ports.
make sure device manager is not showing dead devices (chips) if it is , that means get the missing drivers from Dell, for VISTA. Dell has them on your support page
and we are not DELL.

You cant get in safe mode because the PC hangs before windows ever try to start.

Try to press F8 multiple times but right after the Dell screen.
Some computer don't like that you press F8 while the bios is loading and just hangs there, maybe its your case.

Is it booting to normal mode?

If it is booting to normal mode, click start - run and type msconfig.
Click on Boot.ini tab and Check Safeboot. Click Apply and Close or OK. It will restart the computer to safe mode. Remember to uncheck Safeboot to make the computer to boot in normal mode again.

we have here , like 1000s of black screens posted here now.
all the same all with CCFL lamps. that die. same solution.
older monitors have a power saver mode inside it,
push the front button called menu, then see OSD menu
then find and turn off power saver.
if the OSD fails to show up; the CCFL are dead.
this monitor was made in 2007, and 2010 is the starting year
for ending the usage of CCFL (starting on large screens working to small)

im reading your manual for you now, free.
page 4 tells you it has CCFT (T mean Tube, L means lamp)
same same.

Auto Adjust work on the basis of resolution to which Windows set. It occurs mostly if Video drivers are not installed. Please check and install video drivers and also try to change screen resolutions from display properties in control panel.....
