I wntt to access the power supply fan on my cq2009f desktop. I can remove one side and the front but it appears that I need to remove the rest of the case and this looks like it is riveted to the chassis....


If you want to remove / replace the fan you will need to completely remove the power supply box from the computer case.

There should be 4 screws on the back panel of the case holding the power supply box in place.

Unplug the computer power cord and monitor cable from the back.

Open the computer case and disconnect all the cables from the power supply to the components and motherboard (be sure to keep track of what goes where).

Hold / support the power supply box inside the case while you remove the four screws from the back so it doesn't fall down and break something on your motherboard.

Once you have the power supply box out of the computer case, you will need to remove the 4 additional screws holding down the power supply box cover. Once the cover is removed you will see and be able to remove the power supply circuit board and the fan if you want.

Good luck and please comment back if this was helpful.

I have a problem with my pc it will not boot up it starts to boot then just turns off I cant get and diag done to troblem shoot the problem PC specs Win XP sp3 3gb ram DDR2 Celeron D...


now, this sort of shut down is difficult to diagnose on remote, i would suggest downloading your motherboard manual beforehand. before you do anything, i would suggest read in manual where is reset pin and how to reset bios to original state, but do not do that yet, it will lost all your mods settings and return m/b - bios to original state. there are several possible causes of that fault.

1. faulty memory stick
2. thermal or fault on power supply
3. thermal or fault on motherboard
4. corrupted bios

we will start with easiest to check re 1.
a. switch off your computer,
b. remove power cable from power supply,
c. remove side wall,
d. remove memory sticks and replace them with known working ones from another computer
e. reconnect power supply and switch computer on, if computer works correctly, you solved your problem and need to replace memory sticks

power supply is not much more difficult re2.
a. switch off your computer,
b. remove power cable from power supply,
c. remove power supply cables from motherboard and all accessories, do not remove power supplly from it's craddle yet
d. connect cables from new power supply to your motherboard and processor fan, connect them to your hdd and cdrom,
e. connect power cable to new power supply and start your computer, if computer run correctly, switch it off, remove old power supply and replace with new one

most tiddly bit... when you arrive here that meant that previous two did not solved your problem, re 3:
a. switch off your computer,
b. remove power cable from power supply,
c. disconnect all cables from your m/b
d. connect power supply to m/b and processor fan
e. connect ps2 keyboard
f. connect monitor if "all in one" m/b, video card and then monitor in any other case
g. insert power cable to power supply
h. switch on your computer
i. acess bios (that is usually done by tapping "delete" key, find in your manual) if possible, if not then:
i1. switch off power supply
i2. remove power cable from power supply
i3. re-set bios (you need to locate reset pins/switch/button on you motherboard in manual)
i3. reconnect power supply cable \
i4. switch on the computer
j. acess bios and set your thermal to 75centigrade or 80 centigrade and 5min
k. close bios saving changes
l. re-boot your computer and leave it for 10min, if computer still run, that will indicate your problem lies elsewhere.

checking auxiliaries:
a. switch off your computer,
b. remove power cable from power supply,
c. connect cd-rom
d. reinstall power cable and re-start your computer
e. allow 10min run and check if computer is still running

switch off. remove cable and connect your hard disk drive, run or switched off? if off, you need to check your hdd...

any other auxiliaries need to be connected again in steps and if finaly you find one which terminated boot up, this meant that this particular element is responcible and need replacing. you need as well consider that your power supply maybe perfect on the bench, but will be too small for load required adn simple upgrade to more powerfull mother board can solve the problem.

hope that half book on problem solving solve yours :-)

Red light blinking and no response akai LCT2715


The led is blinking due to fault in power supply board.
On the power supply board there are some capacitors and ICs .if any of those gets short or faulty the power supply board will create problems and the red light will start blinking. The components on the board needs to be checked with the help of multimeter and continuity tester.And the faulty components needs to be replaced with the help of soldering iron. the procedure to check the power supply board is as follows:---- 1) You are going to need a Phillips ( X ) Screwdriver for this procedure. The first thing you will want to do is find a suitable location to disassemble the TV. Try to find somewhere with plenty of space to work and preferably somewhere you will not have any hazards such as static (like carpet)
Lay the TV Flat on its face (picture side down) and remove the 4 screws from the back of the TV holding the base on.
Next you will want to process to remove the screws around the back cover. There are 12 screws you will need to remove (refer to picture for locations).
Carefully remove the back panel of the TV. It may snag on the coaxial connector so be careful.

2) Once you have the back off of the TV you can see the Main board and power supply covers.You will now need to remove the left (right side from the back) speaker cover to allow access to two of the screws holding the Power Supply Cover in place. This is easy and pretty straight forward and has 8 screws around the perimeter.
Once you have the speaker cover off you should be able to access the screws on the side and you will also want to remove the other screws from around the sides of the cover. Some TV's I have worked on only had 6 where others had 7 or 8. Just make sure to remove all of the screws before trying to remove the cover.
Once you have the cover removed you will see the Power supply. Remove the wiring harnesses from the power supply board. You will have 4 cables at the top of the power supply and one main power input at the bottom. The main power input may have some glue securing it in place. Simply cut this with a knife or pull it loose.
Once you have the cables off of the power supply you can remove it from the TV via the screws on the 4 corners. Be careful not to damage anything as you remove these screws. You now have the Power Supply removed from the TV.
you can now get the power supply repaired from any local tv repair technician.or get new replacement power supply from the service center.or from online stores like : www.partstore.com or from www.shopjimmy.com
Thanks. you can rate this solution and show your appreciation.

Hpw do you replace the power source on a gateway MFATXPNT ESX 500S.


How do you know the power supply is the problem?
What issues are you experiencing?
Have you done any trouble shooting first? It could be a bad hard drive.

If you should need to replace the power supply first you need to get a replacement power supply for a gateway MFATXPNT ESX 500S - 300 watt power supply you can get here.

The next step is to unplug the computer from the wall > remove the case side access panel > ground yourself with an Anti-Static wrist strap cord so you don't fry *********** board electronics from static electricity discharge which can cost you a lot more to replace > now disconnect the plugs from the power supply wire harness, it may help to count the connections and mark them with a piece of tape or draw a diagram so you don't forget which loose cables should get reconnected to the new power supply. There will be at least one that connects directly to a plug on the mother board, DO NOT put tape there. > Next remove the screws which mount mount the power supply to the metal frame and slide out the power supply > slide the new power supply in the same way the other other was removed (note top from bottom) and then screw back to frame and reattach the cables > close the case > remove your grounded wrist band > plug computer back into wall and start the computer.

Congratulations, you have just replaced your power supply and ready to go.

IMPORTANT: Do not switch the power output selector switch on the power supply. Usually a recessed re switch which will adjust for european vs. US power input conversion.

Replacing power supply HP M8120N


Here is the link for the upgrade and service guide.

This one is just as easy as 1) removing the side panel; 2) Remove the four screws that hold the power supply into position; 3) Remove the power supply cables from the motherboard (NOTE: If the media bay reader is in the way, you remove the front bezel by pressing the release tabs on the bezel and it will swing open. Remove the one screw securing the bay in position, then slide it forward so you can reach the power cable to the motherboard.); 4) Remove the power supply cables from the hard drives, cd rom drives, and other peripherals inside the PC. 5) Remove power supply...sometimes there is a button to push and it will slide out, sometimes not. 6) Replace power supply, then reverse procedures.

Thanks and please take a moment to rate as fixya.
