Remove the battery from the unit and allow it sit for a couple of minutes then plug in the unit to power and see if it somes up. Removing battery and power often unlocks a unit. make sure hibernation is not causing problem. Once it comes up successfully, power off and reinstall the battery, try again. Some times a failed/failing battery can lock things

I have an e-machine and when I turn it on all it does is blow air. It won't show up on the screen, the fan just keeps blowing! Any ideas?


Check the color of the power light on the monitor (screen). If it is orange, that means you're getting no signal from the CPU to the monitor. If that's the case, check the signal cable going from the CPU to the monitor to make sure it hasn't been disconnected.

Is it possible to put the cpu back in the wrong way? i have just cleaned my comp & i removed the fan over the cpu & the video card? i put them back & now i cant get a signal to my monitor could...


If there is no activity when you power up then it could be the CPU.
Remove the CPU and check the CPU to see if you have not bent any pins. The CPU can only be installed in one position.
The CPU when removed usually sticks to the heatsink.
The CPU should be removed off the heatsink.
The CPU is locked onto the CPU chip holder, lift the locking level up to release the CPU or there may be a locking screw instead of a lever. Turn the screw anti-clockwise to release the CPU lock.
Insert the CPU in the chip holder and lock the CPU in place. If it a screw lock then turn the screw clockwise to lock the CPU in place.
Smear some fresh heat sink compound on the CPU and heatsink and place and then lock the heatsink in place.

Your Problem Is not in your Monitor Its in your CPU. Your CPU is not giving Display Signal to Monitor that's why Monitor goes to power saving mode. try to open Your CPU and remove RAM Clean RAM Slots and Fix it Again. Try to Boot now.

Dell flat screen started flashing, green light was blinking then screen went blank and green light is on. Tried unplugging etc...time for a new one?


No. It is not a Flat Screen issue. It is a CPU issue. You CPU is not sending signal to your flat screen so the green light is flashing. Try to:

1. Reset OR
2. Unplug the CPU case, Open the CPU, the interchange the RAM modules, OR
3. Same with step 2 but unplug and then plug back in all expansion cards like audio, video cards, etc.

It seems that your system needs discharging from a frozen state.

Regards!

No power up on Satellite M35X-s111


Heres the fix:

This requires access to the cpu and heatsink, remove the keyboard and palmrest to access the motherboard, I think you have to remove the screen too. Remove the heatsink and cpu. Reseat the cpu, heres the kicker, press firmly on the center of the cpu while turning the locking screw. Pressing the cpu hard, allows the locking mechinism to get a good bite. Turn the locking screw hard into the end of the turn. Hook up the heatsink and set it back on top of the cpu. Press down on the heatsink over the cpu, fairly strong pressure.

Now test the motherboard, use just cpu, heatsink, memory, power button board and cable and external monitor, you can use your screen instead by just hooking up the cable to motherboard, leave the screen laying flat on the table. Now push the power button with one hand and the other is still applying pressure to the heatsink, no you dont need to screw it down yet. Keep reseating the cpu with varying degrees of pressure if you dont get it go the first time.
The trick will be to get it all assembled with the same results.
There seems to be a problem with the cpu seating correctly, it must come loose and the laptops exhibit the symtoms of no video. It might even be neccessary to insert a wafer thin piece of copper or something in between the cpu and heatsink if the heatsink doesnt apply enough pressure to cpu to keep it seated deep enough to run the computer.
