Try hook up an external monitor (from a desktop pc) to the laptop.
This is just to determine whether the laptop screen is the problem or not.
Then try also,,tapping the F2 key repeatedly as the Laptop is starting up,,will it now enter the Bios on the Screen.
Report back here when you have checked these things.

NO DISPLAY on screen but processor fan is work


If it seems like the computer booted up all the way except the screen is blank.

If so try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok and works, then the video card inside the computer is good, but the original monitor is bad. If the Borrowed monitor does not work, then the video card inside the computer is bad.

If it does not seem like the computer booted up all the way try the steps below.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.

Fan just work for seconds


Replace the fan or your computer will run hot and keep turning off.

Or are you saying this is what happens when you power on the computer? if so: When you press the power button do you hear fansrunning, hard drive spinning, lights on the computer, hear any beeps or lightsconstantly blinking, hear the DvD/CD drive click and the light on the drawer ofthe DvD/CD turn on for a second or two? If so the laptop is trying toboot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Time to look for a new computer. That and take out your hard drive to copy your files over.

Sounds like motherboard problem. Probably not worth repair.

I've got an HP desktop with similar problems. It turned on one day just fine. The next day not. I don't even get the boot up screens. Disconnecting Hard Drive and CD/DVD components do not help. I should at least get some BIOS POST beeps and a Hard Drive Not Found or such. I do not. On occassion it will boot to a blank screen with white cursor in upper left. Most the time no screen at all. On rare occassion it comes right on and boots Windows. I guess it could be the power switch ... but I doubt that.

Power on emachine T6420 and moniter is blank. The moniter soon loses contact with the computer. The fan run and power is OK there is no beep code.


If you mean after the computer performs the self test the screen goes blank and stays blank, eventually turning off you are having a hard drive problem. When the computer boots you should see an E-Machines logo and/or a self test on the screen. That is done by the motherboard as part of every boot up. After that the motherboard passes control to your boot device and loads your operating system. If your computer stops booting at that point, your boot device is not working properly. That could be caused by many things - virus, hardware failure, power outage. If you really mean you see nothing at all on the screen when you press the power button your computer simply is not working at all. Open the case, blow all the dust out of it and reseat all components you can, then try again.

Getting power but wont boot up or anything


pull out everything in the computer except what's required to boot...so any pci cards or video cards (if you have onboard video). you can also try pulling out the ram (while unpowered AND unplugged) and then booting to hear beeps...if you pull the ram out and the computer doesnt make a sound, its probably a bad motherboard and needs to be replaced. if you hear beeps, try replacing the ram or disconnecting other parts...like harddrives, optical drives, modems and what not.

DO YOU KNOW WHAT A MOTHERBOARD IS?

IT MIGHT BE A PROBLEM WITH THE CPU....TAKE TO A COMPUTER REPAIR SHOP
