Hardware Motherboard issue , seeking advice circiut expert

[Foxi4]

main question was , does the button do anything when decompressed ? pretty sure it does not ... so gutting it or removing should act the same way as if it was functional .... just dont want to take it off and mobo be dead as result

It probably does absolutely nothing like 99% of the buttons on your motherboard unless pressed. Most buttons are only active when pulled low by connecting to ground. If you gut the button, you'll permanently remove the connection.

Already pointed in the 4th Post....

And in the BIOS there are maybe "other Possibilites",if he tell us the Mainboard Type....

when it acts up it's like you are pushing it over and over again ..... its the button ... blow can air at it and pc restarts .....


main question was can I remove it from the pcb

One last Try:

Disable "Direct Key" in the BIOS.....if possible.

thats what I figured

--------------------- MERGED ---------------------------

it had the USB 3.0 wire putting pressure on it when I got it , I think that is what caused the failed button

You can probably disable the button in the BIOS as mentioned. That will save you some time diagnosing. Check the documentation for your ASUS P9D WS. A quick Google lists the option to disable the key before you butcher your board for possibly no reason.

that just disables using the reset button on the case as the direct key

That's not what the documentation states. You have two options - Disabled (Directkey will power the PC on and off) and Go To BIOS (Directkey will reboot the PC and go directly to BIOS instead of booting into the OS). Don't you think that would help you diagnose the issue? If it suddenly starts going into the BIOS, you'll know for sure.

The manual online and the one that comes with the board are diffrent , and what the setting in the bios says also ... states enable/disable the reset button as the direct ket button.... its so if you have fast boot enabled in a UEFI setting you have a easy way to get into the bios , the bios setting is so you dont have to take off the panel to push the button .... or in other systems clear cmos

--------------------- MERGED ---------------------------

Think of it as if you hold the button of keep pushing it

You should have the option to set it to Go To BIOS from the Boot Settings menu, it's literally the only reason why a WS board has a Directkey button at all. You may have flashed an oddball BIOS or the setting is hidden. With that being said, you do you - it's your board. All I can give you is wise council, like the other users here.

its the button , for sure ... just wanted to make sure I will be fine removing it ...


also the 1070 ti in it I paid $85 for with some bad caps and mosfets , replaced those and its good ......


the directkey is bad due to the USB 3,0 wire resting on it putting pressure, the bios setting is to you the reset buttion as a external directkey ....

its the internal button ,,, just wanted to be sure gutting it wont removed a circuit , and even if it does I can trace that circuit back.


Thank you everyone for the help , I been working on computers for over 20 years and was just unsure about one thing ... but I had the question answered ...


will report back this time tomorrow if the issue is gone removing the button ...




again thank you to everyone , I know it seems deeper then it is but its not ..... thanks for trying tho ... but its just a bad button and I wanted to be sure I can remove it

I mean, it's hard to help you if you don't have a meter and can't probe the contacts. We can't tell you what's under the soldermask, you have a better chance seeing the tracks than we do on a tiny picture. If you had a way to probe it, you could check continuity between the square pad and the three round pads to determine if it's malfunctioning and how it's connected, but in the absence of that, just YOLO on a safe bet. Good luck, hope it works out for you.

Well yeah , but then I would have to pull the board out to show the back to show the traces , not wanting to tear it apart


Was just seeing if anyone understood this type of button more then me , I have taken them apart and studied them before , but dont know everything , its the bottom --- that's a fact ....... was just looking for insight on that matter ......

You guys are awesome and thank you ...... wish I had had the time and money to send this board to every one so they can see what I mean, I'll try to record it........

Given the fact that DK also has a seperate header for an external button, I think it's safe to assume it connects to ground, otherwise it would have to have a jumper on the header pins in order to function. I'd say you're safe, they wouldn't run two separate and functionally different circuits for the same thing.

 

[Undwiz]

only found the issue with the button because it has a lot of play compared to the Memory training button above it

Alrighty , may same thoughts ..... not sure if you looked at the before and after pics ,,, but I got it looking great....


so why I dont want to tear it back apart ........ just going to shave the 4 corners off and remove the guts of the button ... large case so I dont have to remove the board to do so ......


thank you for the help........ will check back ......... hopefully it does not remove a connection then I got to trace it and repair



these buttons have a small dome foil like crap in them , one little dent and they will do things like this


Also ... I had a stroke 5 mounts ago ..... I have a hard time speaking and typing my thoughts ... it al working in my head but hard to let out

 

[Undwiz]

removed the 4 blacked corners , took out the guts ...... touching the metal causing of the button no longer resets the system , can air no longer makes it reset ...... took 3 mins to remove and gut .... button is now gone and no more problems


no longer goes to BIOS after a reboot

 

[Undwiz]

I know this is more a console site , but knew I would get a answer ........ just a side note last hard mod I did to a console was a OG Xbox using a Xenium Ice------ like 16 yrs ago






Edit--------

forgot my old user name --- but been here for 15 yrs-ish

Update still no issues !!! taking off the button did the trick

 

[Undwiz]

we mentioned, i doubt he understands what we're saying here, everything he claims about the button is just the behaviour it should trigger, it doesn't sound like its the button it's unlikely to be the button, but let him try it, it's better to have tried, just hope he's not gonna sell afterwards, cause he's sure in for warranty claims.

And well it was the button , I doubt you took the time to read and was able to just understand I knew what I was saying .... but yeah bud.... next time don't take it like you know everything when you are not the one with a hardware

no i read all posts very well, said the button could be removed like every button in any hardware can be removed without any problems, battery, diode, resistors or capasitors could be a problem to remove.
i never said it was not possibly the switch, just pointed to it be unlikely the real thing since like i said though the button is sensiteve it acts like designed when you described the actions of the button, since these buttons are small they seem to trigger by about any force even if not supposed to.
special computer repairs for over 14 years now on component level as it is my profession, working for Carrier Transicold.
happy to see it seems fixed by the button, but i'm really not convincedit will stay fixed.

See pic to see the button in question.


Got a old workstation for cheap , the guy thought the MOBO was bad..... it would turn on then off in loop at bootup.

I found that the DIRECTKEY button is faulty and if I pull it out the PC will work for a few days a week 2 weeks ... just random then it will act up again...

The MOBO button is in PIC..... Just touching not pressing the button will make the PC reboot shut down ect....


My question is , will gutting the button or just breaking the button of be a problem ?

I have taken buttons like this apart before , has a dome clicky thin metal in it , those tend to fail .-- thats what completes/shorts a circuit when pressed in.... from what I believe ..


so my question is can I dissemble the button or just remove it with no issues ? hope I made it clear ...


main point , can I remove button in pic ? Thanks

You might be able to just twist the button off (gently back and forth until the solder points break loose)
It works for capacitors.
Worst case you could ruin the solder pads but I guess that button isn't really that important anyway. Although I was amazed at how well it worked with capacitors, no damage to the pads at all.
