Well, lots can cause this, but I'll try to address a few common ones. Check to make sure the a/c adapter is powering the laptop. Feel if the fan is pushing air out the exhaust, if not, take the laptop apart & clean the cpu heatsink & fan.

Moniter goes into sleep mode after i turn it on. Have to turn off the monitor for 20 seconds and then it comes back on for about 20 seconds and goes back into sleep mode


This may be a problem with the monitor, such as a failing video board, or it may also be a problem with the video card in your computer. If you can try the monitor on another computer or try a different monitor on your computer, you will have the answer. At the price new 18" widescreens are selling for (sub 100.00 in Canada), I would have a hard time justifying spending too much time or money trying to fix this one.

The security system locked the jeeps ignition but i dont know how to restart the system and i try to start it and it wont not even jumping it help


if you have both ' original ' keys that came with the Jeep - you can try and flip them through the system and get the Jeeps computer to accept them,, take both keys and sit in the drivers seat -- with one key put it in the ignition and turn to the on position - wait about 15 -20 seconds, remove the key and then put the other key in and turn to the on postion -- wait 15 to 20 seconds,remove the key and now put the first key back into the ignition and turn to the on postion and wait 15 to 20 seconds,,, now try and start the Jeep.
now if one of the keys is not an original key ( a clone key ) -- then this might not work,, and you will need a automotive locksmith to come out and re-program your keys to the Jeeps computer. since you already have keys, this is not a very expensive trip -- you will just be charged for the service call and the programming of the Jeep.

My computor monitor shows OSD lockedout


Plug in the monitor and power it up. Hold down the Power button until you get a message saying “OSD Unlocked”. If the problem persists after OSD is unlocked then unplug the monitor from the wall, wait 20 seconds and try again

Turn on the monitor and hold down the Menu button for 10-20 seconds. This should unlock the OSD

Turn off the monitor, press down the Menu button and then turn on the monitor. Wait 10-20 seconds. This should unlock the OSD.

The Menu button may be stuck in a pressed in position. To get it “unstuck” you’ll usually need to open up the monitor. This could be tricky unless you know what you’re doing. Unfortunately there are too many models of monitor for me to provide detailed instructions. If you have warranty this is where you want to contact the manufacturer.

My sansa mp3 player will not turn on


This happened to me today, which was what brought me here. Also, when I plugged it in to recharge, my computer didn't even recognize it. The SanDisk troubleshooting said to hold up a power switch, which I didn't have, for 20 seconds. So I held the power button down for 20 seconds. (Much longer than the usual amount of time required to turn on). At first I thought it didn't do anything, but then when I pressed the power button again briefly, my SansaClip woke up, was recognized by my computer again, and in every way behaved normally.

Have you tried any other monitor connected to your computer since your current problem? Check your connections, make sure your VGA cable/DVI cable are in good condition. If none of that works try to RMA it to sceptre if your still within the 1 year period.

Monitor goes blank less than a second after turning on.


I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.
