Solved How to take out 24 pin connector from motherboard

February 20, 2017 at 05:25:19
Specs: Win 7, Intel dh61ww mobo,wsm 800w psu
I am not able to take out 24 pin PSU connector from
Mono.I want to clear CMOS but it can't be done as my PSU gives some charges to mobo even if PC is off

Any more ideas !!!

@Brorocking

Okay. More Idea ...
PSU is not your problem !!!
When System is Turned OFF and Main Power Cord Unplugged, Mobo Works as short circuit and discharges Capacitors of PSU !!!
IT IS IMPOSSIBLE (WAIT FOR 2-10 MINUTES, for capacitors discharging via mobo).

STANDARD METHOD IS :
1- Set CMOS jumper (near the BIOS chip,Usually) To Clear Satatus (Read Manual Or Read Printed Words On Mobo)
2- Remove Back-up Battery of BIOS-CMOS MEMORY (IF PROBLEM EXIST AFTER SETTING CMOS JUMPER)

OTHER METHOD :
NOTE : Make a backup of System BIOS, you will need to run the BIOS upgrade software to read BIOS contents to a file BACKUP BIOS !
DOWNLOAD MANUFACTURER BIOS SOFTWARE, AND SAVE CURRENT BIOS (BACKUP), UPDATE BIOS AND BY USING PARAMETERS, WRITE AND SEND "CLEAR CMOS DATA AFTER PROGRAMMING" COMMAND TO PROGRAM.
IT WILL CLEAR CMOS DATA AFTER UPDATING.
YOU MAY HAVE DAMAGED BIOS AND/OR MAINBOARD/MOTHERBOARD/MOBO, ALSO.

Good Luck .

Those connectors can be very tight - need levering up each end.

With the PC power unplugged have you tried just holding the Power Off/On button for at least 20 seconds? This usually discharges the motherboard components.

Always pop back and let us know the outcome - thanks

Hi Brorocking,

if it is that tight, it is best left alone unless absolutely necessary, otherwise damage could occur - to the motherboard even, which would be very expensive to correct, if possible..

Bear in mind some voltage could be coming from the cmos battery.

Good Luck - Keep us posted.

"my PSU gives some charges to mobo even if PC is off"

Of course, that's what it's supposed to do. Rather than risk damage to your board, how about unplugging the power cord from the wall outlet? And if your board has a clear CMOS jumper, use that rather than messing with the battery. Just move the jumper, wait a few seconds, then move it back. I already explained that to you in response #2 of your other post:

OK, so what's the problem?? If you did it correctly, the BIOS has reset. If the board isn't booting up, you have a different problem. Do you have a speaker connected to the board? If not, get one. You need to hear the beep codes.

piezo speaker

standard speaker

As of the topic how to remove 24 pin connector,never try to remove it if it is not coming out even after pressing the latch down and applying nominal force..I learnt these connectors are mostly soltered with mobo..so just leave it to professional s only

Brorocking

Your information is faulty. The 24 pin connector referred to is the end of a bundle of wires that originates from the Power supply. It is NOT soldered onto the motherboard. The SOCKET the 24 pin connector plugs into IS soldered onto the motherboard.

#3 above provides the correct procedure to clear the CMOS. IF the PSU does NOT have an ON/OFF switch, then it is necessary to unplug the computer from the AC current.

I did encounter a situation where the Power connector (20 pin at that time) was overheated and the plastic parts fused together. This was caused by setting the voltage selector to 120VAC in a part of the world that uses 240VAC. That results in feeding twice the normal voltages and will fry the motherboard.

New PSUs no longer have voltage selectors but can sense the incoming voltage and adjust accordingly.

This thread is marked as solved. Is your problem now solved? If not state so here so additional suggestions or clarifications can be made.
