After completly setting up the computer after a move, it doesn't power up. The power cord is fine and the outlet it's plugged into is fine, the front power button still clicks, and we cleaned the inside, but it doesn't make a sound when we hit the power button. Everything inside seems to be in place. Any suggestions?
Have the same issue..When I shutdown or power goes out I can not power puter back up..Power LED on back of unit below cord flashes..I found if I opened up unit while plugged in and pulled main harness of of main board and slowly pluged it back in a few times LED would eventually stay on solid green and unit fires up..Have had this issue for about 1 year and really doesn't bother me anymore now that I have the trick to start...
Could be the power supply I was told but who knows..

Re: won't power up
When you turn the PC on check for any active LEDs on the front of the PC, keyboard or the back. Also check the fan on the back of the computer to see if it starts or at least moves. Are there any humming noises when you power up? If you find anything let us know so we can proceed, otherwise ?..
If there is absolutely no activity and if the machine was handled relatively well during the move I would be more inclined to suspect the PC just isn?t getting any power.
-Try getting rid of any UPS or power strips and plug directly into the wall sockets.
-Even if you can plug a light into the wall socket and it works that?s only a partial test. For under $5 you can buy a power socket tester which can warn you about incorrectly wired sockets (incredibly common in the States) that can affect PCs.
If this doesn?t turn up anything your power supply or something else coincidentally could have died during the move. Let us know if you get to this point and we?ll continue otherwise please don?t forget to rate this posting.
Hey guys i have the same problem when i move to a new house my presario s5100nx doesnt turn on when i press the power button. I really need this computer so i toke it apart and cleaned everything. after a few weeks i said let me spin the fan in the back so i got a hair dyer and turned it maxed power and spined the fan. About one minute i just rapidly press the power button while the hair dryer is spining the fan then it will start. I been doing this for 5 months now and its annoying waking up in the morning doing this and waking up everyone lol but it fixed a 400 dollar problem lol.
I have the same problem and all the sockets work correctly, but the computer still doesn't turn on. It had a spurt for a while where when it was shut off, it would take a long time to reboot. Like I would shut it off and I had to wait about a day before it would let me power it back on. As time passed, the length of time that I had to wait increased, and now it doesn't turn on at all. The power from the outlet is good, and the LED lights on the back work, but I don't know what could be the problem. Any thoughts?

Try this approach: 1. Remove the power adapter from the printer. The power adapter is the black box where the power cord is plugged in at the back of the printer.2. Disconnect the power cord from the power source.3. Reconnect the power cord directly to the power outlet in the wall. Bypass any surge devices or power outlets.4. Re-plug the power adapter into the printer.5. If the printer won't automatically power on, press the power button on the printer operator panel. I hope this helps. Should the problem continue, please contact Lexmark Technical Support Center for additional assistance.
Assuming you have tested those outlets with another electrical device (such as a lamp) and they are getting power, the problem might be the power cord, or static inside the computer. Try this:
1. Remove the power cord completely from the computer. 2. Press and hold down the power switch for 10-20 seconds. This drains any residual static in the circuitry. 3. Re-attach the power cord. Make sure it is seated firmly on the end that attaches to the back of the computer. 4. Plug it into a known good outlet and try to power on.
If that does not work, try replacing the power cord with a known good one. If it still doesn't power up, the problem could be either the power on button, or the power supply itself. Either could have been damaged during your move. You could open the computer case and see if anything appear loose, or any wires are obviously detached.
Power supply modules do ocassionally go bad on computers. They are not that expensive to buy, and not that hard to replace, though it might be a challenge for a novice. Before you buy and/or replace the power module, be sure to have the machine tested at a local store (Radio Shack, Best Buy, Office Depot, etc) to make sure that is really the problem. Many stores will perform a power supply test for a nominal fee.
Remove the power cord.
Locate the 120V / 240 V ac selector switch. (within 4 inch from the power inlet)
Move it back and forth few time.
Make use it's set to the correct voltage selection.
Reconnect power cord and power up.
This AC selector switch can get shifted and set to different position.
This may be a longshot, but many electronic devices like TVs, dryers with electronic computerized controls, entertainment systems like the Wii, and other devices sometimes get "confused" and won't turn on, turn off, or otherwise work properly, perhaps due to a small power surge in your AC line.
I've found that one of the first things to try when it appears to be a failure of the electronics and not a mechanical issue is to unplug the device at the wall (to make sure that any power adapter is also unplugged) and wait about 10 minutes for any residual electric charge to dissipate. Then plug the device back in and give it a try. This has worked with a television, a Wii console, an electric clothes dryer, and some other devices that I thought had died for good. This may explain why sometimes a device is taken to a repair shop and it works fine.
There are, of course, other reasons that the unit won't turn on, but I would try this first before looking for other reasons for the problem.
Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.
If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.
Then unplug the power cord from the power outlet. Wait at least 10 seconds before re-plugging the power cord into the power outlet in the wall (bypass any power strip) and the power adapter into the printer. This will give enough time for the printer to reset itself. If printer won't automatically turn on, press the power button. If that doesn't help, please contact Lexmark Technical Support Center for additional assistance.
