Just put my system into Sleep Mode last night and how I cant get it to boot. It sounds like the hard drive is being accessed but the screen is black. Mouse and Keyboard activity have done nothing. Removed all items from computer. Then removed power cord. Held power button for 30 seconds and restored power. Again it sounds like system is starting but the screen is black! I have had this system repaired and major boards replaced several times; including the inverter board. It was working fine till I put it into sleep mode. Any suggestions to get this fine quality system running?
Thanks
