The PA system chargers but will not power up. I opened it and it turns out that if I take out the fuse then put it back in it powers up, but when I turn the power off then on again it doesn't want to turn on. Fuse works fine, connection is troublesome. My question: is there a way to work around this??

del recognition circuit may have failed in charger , or could be fine central pin on charger plug or laptop plug has broken connection,it is used to tell laptop that this is genuine dell charger.If you remove battery will laptop work off charger.if does then definitely one of the three problem possible . for first only soln try another dell charger first,often has to be one to suit your model ,common dell problem ,if then work and charge battery ,you will need to replace charger as recognition circuit failed. If either of last 2 can repair but need to pull apart repair broken connection ,or open up laptop and check power connection and repair connection . If you remove battery will laptop work off charger.if does the definately one of the three problem possible . for first only soln try another dell charger first,often has to be one to suit your model ,common dell problem ,if then work and charge battery ,you will need to replace charger as recognition circuit failed.
for the past month i have been shopping for the perfect home theater system and have narrowed it down to a bose system,a sony system and a paramax p510...i have listened to all 3 systems and have found the paramax to be the better system not a cheaper system but seem more bang for my buck at 3200$,a very powerful tube amp and downfiring sub maxes out at 2000 watts...
Open the case and look for a jumper switch (usually blue or black color) labeled CLRTC or CRL. A jumper switch is a small connector connecting two pins on the motherboard. Same like the one in CD ROM drive or hard drive for selecting master or slave.
If you find it, unplug the power cable, remove the jumper. Wait 10 - 15 seconds, then put it back. Plug the power cable and try power up your computer.
