My computer lights keep flashing

Ensure there is only ONE item connected to Bluetooth.

if you're able to re-flash the firmware, it should help you alot. usually the problem started because of the lamp unit in the back light.

pressing power on button should be for 30 to 40 sec but the flashing lights means there is a hardware problem can find flashing light codes on the net you could try removing ram 1 by 1 c if that works hope this helps if not will keep an eye on this

green=power in motherboard.
blue=stand by.
yellow=memory powerd

hello there's a couple of things that could be wrong .the high pitch noise could be the convegance chip shorted out these are 2 big black chips connected to a metal frame called a heatsink the other could be the lamp burn't out

shaun

go to control panel
make double click on printers
right click on your printer icon and click on online
it should work

What do you mean it powered on to the blue light?
Does anything show up on the screen?
Does the system usually beep when it starts? If so, does it beep now?

I think your SMPS has gone bad. Get it checked from a qualified person

Hi...there,
It's seems you got a busted AD Board... your LCD bios had been damaged or erased.

sounds like something is drawing down on your 12 volt supply drives or on board regulators. Try it without the drives connectged, and see if you can get the system to boot up(you'll just get a notice that your drives are unavailable, but you'll already know that, right?

got backup for your Dell?
