Re: Opening the case to change power supply
Its not difficult actually. Just unscrew what you see and the power supply is on the left. there should be 2-3 screws not visible enough :) and take out also the 2-3 cables that are visible enough. The PS is pulled from the down site to be replaced
a 6ya expert can help you resolve that issue over the phone in a minute or two.

you should not have to run a double wire to the thermostat and the power supply. you should be able to come from the power supply and wire the supply and then the other to the t-stat but do get a second opinion. watch the color coded wires though manufacturers changed them to confuse the d i y er
This guide was developed to instruct readers on the proper procedures
for installing a power supply unit (PSU) into a desktop computer case.
It includes step-by-step instructions with photographs for the physical
installation of the PSU into a computer case.
IMPORTANT: Many name brand manufacturer PCs use specially
designed power supplies that have been built specifically for their
systems. As a result, it is generally not possible to buy a replacement
power supply and install it into these systems. If your power supply
is having problems, you will likely need to contact the manufacturer for
CAUTION: All power supplies contain various capacitors
inside of them that retain power even after the power supply had all
power turned off. Never open up or insert any metal objects into the
vents of the power supply as you can risk electrical shock.
To start with installing a power supply, it is necessary to open
up the case. The method for opening the case will vary depending upon
its design. Most new cases use either a panel or door while older
systems require the whole cover be removed. Be sure to remove any screws
fastening the cover to the case and set them aside.
Align the new PSU into place in the case so that the 4 mounting holes
align properly. Make sure that any air intake fan on the power supply
that resides in the case is facing towards the center of the case and
not towards the case cover. Now comes one of the most difficult portions of the power supply
installation. The power supply needs to be held in place while it is
fastened to the case with screws. If the case has a shelf ledge that the
power supply sits on, it will be easier to balance.
Make sure that the voltage switch on the back of the power supply is set
to the proper voltage level for your country. North America and Japan
use 110/115v, while Europe and many other countriesuse 220/230v. In most
cases the switch will come preset to the voltage settings for your
region. If the computer already has the motherboard installed into it, the power
leads from the power supply need to be plugged in. Most modern
motherboard use the large ATX power connector that gets plugged into the
socket on the motherboard. Some motherboards require an additional
amount of power through a 4-pin ATX12V connector. Plug this in if
A number of items reside within a computer case that require power from
the power supply. The most common device is the various hard drives and
CD/DVD drives. Typically these use the 4-pin molex style connector.
Locate the appropriate sized power leads and plug them into any devices
that require power.
At this point all of the installation and wiring should be completed
with the power supply. Replace the computer cover or panel to the case.
Fasten the cover or panel with the screws that were previously removed
to open the case.
If you mean Power, then your psu (power supply unit) has most-likely gone bad. This happens a lot when a computer is as old as this model is. If you have no other choice than to replace the power supply, be sure to use dell in the search, models of this era did not have an opening on the back to accommodate a power (on/off) switch so you must get a replacement that will fit the case and not need an opening where there is not going to be one.
If you meant anything else, you need to explain better.
[ If it were I, I would change the computer case, so I could use a standard ATX form factor power supply. Cheaper, more reliable, more wattage, and high quality MosFets, Capacitors, Rectifier Bridge, and other associated SMPS parts are used.
Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacemnent from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day.
At the least it will be a new power supply. Does it have an external PSU or is it internal? It depends on the quality of the power suply wether any further damage was done.
Either way if you need the data you could open the drive case up and remove the drive from it, you could then fit it as an internal disk on a desktop PC to get the data back. Opening the case won't matter as you have voided any possible warranty by changing the supply voltage.
Sounds like a blown fuse. You could replace that, but opening the power unit will void your warranty and the unit itself might be damaged as well. My advise would be to buy a new one unless you really know what you're doing, a half-broken power supply could damage other hardware or even start a fire (worst case scenario).
