My 8300's power button has been acting strange; it requires a few pushes to turn on the computer. The frequencies increased last few days and now it completely refuses to repond. I checked the connector on the system board, checked the cable and called Dell Tech Support; but still can't figure out what's the problem. Dell Technician suggested changing the power supply, but he is not sure if that's going to solve the problem. I am thinking perhaps the power button is not working, but I don't know how to take off the front cover to examine it. Dell Technician suggested going to a repair store, but that's going to costly and not necessary helpful. Hope someone can help me here.

I have an HP printer too, but it's HP 2050. When i plug it in it usually makes a noise and then the power button blinks. To turn it on requires me to hold the power button down for a few seconds until the power button light stays on. If you haven't tried yet, try pushing down and hold and see if it turns on. Hope this helps :)
Hi Paul. There are few possible causes for what you've described: 1. The outlet doesn't work properly - Try using a different one. 2. The power adapter is mulfunctioning or doesn't match your laptop - try using another original adapter or a generic one (make sure the Voltage is EXACTLY the same as your laptop requires and that it supplies enough Current). 3. The battery has gone bad or finished it's life-cycle - Replace the battery. 4. There's an electric problem with the power circuit on the motherboard - replace it in a service center...
Sounds like there maybe bad caps on the power board in the LCD.
Try a different monitor on your computer and if the known working monitor comes on with the computer and behaves properly then you know its a problem with your original monitor. If the known working monitor acts strange as well then you know its a problem with the video card.
Let me know what happens.
open the side- and along the just inside the front exposed edge there are several tab that get push inward to release the front. They have a tendency to catch again when you go to the next one...you'll just have to play with it a bit. once that is open you'll see the other little plastic tab that holds the switch assembly . Don't forget to UNPLUG the power supply.
The Dell 8300 does not use industry standard parts. You need Dell specific parts in order to replace the fan. Here is a link to a replacement fan shroud assembly for your Dimension: http://www.discountelectronics.com/index.php?l=product_detail&p=845
You may be able to find cheaper if you do a Goggle search and dig deeper. Hope this helps & please take a moment to rate this solution. Thanks.
ok, to get at the switch board, take a flat bladed screwdriver and /carefully/ lever the outside ends of the hinge covers vertically upwards. Once the covers are free (you'll find that they are attached to the blue strip), slide the blue strip and hinge covers to the LEFT and then lift. The strip should free from the chassis. The switch board should be held in by two screws (one holds a lug to hold down the keyboard) and connects to the motherboard via a ribbon cable. The part number for the switch board is printed on the upper side of the board. You might find it advantageous to order a new ribbon cable as well; both parts should be readily available from your newarest independent service centre or direct from Dell.
If your craddle has DC power input that charges the PDA while in craddle, try setting the power configuration so that when the PDA is on external power, there is no blank screen timeout, and no automatic shutdown (it's in the Settings menu). This way, it won't power down while in craddle, and you won't get this problem you're having.
