Most times a break in the wiring is not visible and can occur inside only one wire in the mains power cord several centimeters from the power appliance. The first thing to ascertain is whether there is continuity between the plug pins to the junction. You will need to use a polarity tester. If you don't have a multi-meter you can use a small battery and torch bulb and run them in parallel. Test both the positive and negative wires. If one wire fails to provide continuity then rewiring will solve your problem.
Alright so you need to pull all of the screws out on the bottom of the laptop. The casing will most likely require a little force due to any sealant that the company used if this is the first time opening it. you may also notice a little locktight on the screws that you have pulled out. You just need to run your fingernail or a flatheaded screwdriver around the edge of the panel and pry it off little by little.
Let me know if you need further directions or have other questions and I would be glad to do what I can.
Open the case. Disconnect all cables from power supply. Unscrew the power supply. Remove it from the case. Install the new one. Screw it. Connect all needed cables. Close your case. It's done. Turn on your computer and enjoy.
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.
First thing to do is shut down, pull the power cord, press the power button for 10 seconds to bleed off the ectra power, open the case, Take out the memory modules and then reseat them carefully. Power the system back up with the case door open. If it boots up, shut down, close the case and reboot.
FIRST FAIR WARNING: This take apart is best left to the repair tech's at an authorized repair facility. There are 6 snaps, two on the top, two on the bottom and one on eash side. I used a thin blunt tip letter opener and started at the top. This didn't leave any marks on the case that would tip off the repair tech's that you goobered it up inside which you will do if you proceed! Release the two at the top first, then the two on the bottom. Now release the one on the side where the power button is located. Open the case on the power button side only about 1/4 inch and slide the bottom off the top being careful not to separate the power cord and headphone connector plugs from the board that they a fastened to inside the case. SECOND FAIR WARNING: It is very easy to pull the connector plugs from the board and this will really convince the repair tech's that you ruined your $350 GPS. Good luck and don't say I didn't warn you!!!!!!
