Re: Monitor says no signal

If the beeps when u turn the pc on are longer than normal this can mean that something to do with the computers memory is malfunctioning. Check the memory processors, and memory related itmes in the pc to check for loose connections.

When my Computer turn on the system Giving message "Monitor is going to sleep mode" and then I am not getting any display, but the system is on.

Monitor is not getting a signal from the computer. Ensure the cable connections are correct. If the monitor has a input select option, ensure it is set for the cable option selected.
If tower is a Dell, ensure the power LED on the Tower is Green/Blue If flashing Amber, power supply may have failed, solid amber, motherboard or a device connected to it may have failed.

Wont start up

Check physical connections first, check monitor cable if securely plugged in and then check power light of monitor. If power light on monitor is amber or yellow it means that monitor is not getting a signal from cpu/ tower. Try to do a power drain on the computer, remove power cable at the back of the computer and then press and hold the power button for 10 secs, after that plug in power cable again and restart the computer.Check if there is any connection if not then try to use another monitor, a known good one. If you get a video from another monitor it means monitor is already defective.

Dell Inspiron Vostro 530s won't boot.


I work for Dell, If the power button led light is flashing amber or amber (the Power supply is faulty) The Yellow light you saw inside the motherboard is the "Flea Light" (that is one way you could check if there is still power on the motherboard). Since the motherboard was replaced there are a few more things to check:

1. Video card (integrated or expansion)
2. Monitor (Make sure it displays self test feature when the cables are removed)
3. Monitor Cables (VGA / DVi)
4. Power Cable on the Monitor (try a different cable)
5. Power Supply (you already checked, but i suspect this is causing the problem)

Hope this helps.

I'm not clear about the blinking amber light you are referring to. Is it on the computer or the monitor.
I checked Dell's web site for the service manual for this computer model, & found this document:

If the blinking amber light is on the monitor, check the connection between it & the computer itself. Make sure the cable is not damaged & that it does not have any broken pins in the socket.

If the front Light is flashing amber, the systems power supply has gone bad. Request you to replace the power supply and the front I/o panel and power switch . The issue would be resolved.

Does not power up

Is the amber light flashing on the monitor?

If so, you should get your power supply checked.
