Emachine 4252 wont start fan comes on and runs constant no light at the button monitor says going to sleep

No monitor model told
no PC model told
no OS told
also PCs with wrong drivers, the sleep mode fails.
so turn off sleep fully in the control panel + power settings
go to performance mode.;the blow flashing light means I AM sleeping but THERE ARE ONLY 3 WAYS TO END SLEEP ON A DESKTOP(NO NOT FIDDLING A MONITOR)
wiggle the mouse or click it but of USB ports are allowed sleep that fails. hard. so never allow usb to sleep.
then way 2, hammer the space bar ,keyhboard or the ESC key
see PC exit sleep, if USB is allowed to sleep (ports)it too fails
and last the power button pushed in for 10second and released
forces a sick PC, (bad drivers that kill sleep features) this act resets the PC and reboots.
why not just turn off all sleep modes. and just allow the monitor to sleep and or power it off. not used.

also page in your manual states (see resume)
and never allow Hibernate at all it is super buggy or any deeper state.

"Press this button to turn the power on
or off. You can also configure the power
button to operate in Standby/Resume
mode or Hibernate mode. The power
indicator lights when the computer is
turned on."

why not test the PC with newer monitor 2011 newer LED back lighted monitor to be sure your older monitor is not bad as seen here in this flash light test.





rCAP
learn to disable all forms of sleep modes, ALL no exceptions.
then see if this works if it does you just learned your drivers are bad.
or test the PC with a newer monitor 2012 is LED for sure)
learn that bad drivers most times make sleep fail
no oS told at all, not even a tiny clue is this XP the versus magnet from H3LL>? or worse upgraded to vista and drivers are all no good for vista. never up grade any os lacking oem support for all drivers.
newer. vast PCs have no upgrade path at and guess what
emachine is infamous for that fact. they stink this way but sure wins the dirt chip cost war, sure.
the fast resume is on the power button to set right]
the fast press is resume from sleep, the but is programable.
if drivers are wrong all this fails hard,

Change your sleep settings in the Control Panel under Power Options. You can set it to never go to sleep or have it to go to sleep after 2 hours. There will be settings to control when the monitor shuts off, when the hard drive shuts off, etc.

There is your answer no power to the monitor. Make sure it is plugged in replace with another monitor if you cannot get the button on the monitor to power on the unit. Maybe time for another monitor. John

The amber power light indicates that your computer has been "sleeping" or "hibernating" and usually all it takes to restart the computer is tapping a key on the keyboard. If this is not the case, try holding the Power switch down for 6-10 seconds to force the system off. Restart in Safe Mode and try to find the settings for Sleep/hibernate, open the control panel and open the Screen Saver. Select "Change Power Settings" and set it for "Never" on sleep and hybernate.

check to see if you system is on ... might be sleeping ... second restart the computer and check your connections .... let me know if this helps

Did you remove the CMOS battery and move the jumper on the systemboard to clear the CMOS? After a few minutes or so, put the jumper back and power on the machine. If it powers on fine, you can turn it off and put the CMOS battery back in.

Actually, the monitor is fine. The problem is that the computer isn't booting. The power comes on and the fans spin, but the system board isn't starting. Try reseating the memory modules in their sockets and clearing the CMOS memory using the jumper on the system board. If the problem continues, try another power supply. Finally you may need to replace the system board.

when i on my computer it say monitor going to sleep

different beeping patterns are codes which indicate what part of the hardware has failed (ram, video card, cpu, ect). the fan failure would not cause beeps, and would not cause the cpu to fail unless already in windows. if you could find out the manufacturer of your motherboard you could check with them about what the paticular pattern of beeps which you are getting mean.

got the same issue
