Clear CMOS jumper position

I have a P55A-GD65 motherboard.
I'm wondering which position of the JBAT1 jumper corresponds to 1-2 and which to 2-3, as I cannot see any labeling on the motherboard, nor is the manual clear on this topic.

If you never touched the jumper before, and the board has been working fine, then the jumper is currently in the 'KEEP DATA' position, which is pins 1-2.

Clear cmos jumper

P43 neo board (ms-7519)
Could someone confirm which is pin 1 on the clear cmos jumper. From the manual it looks like the pin nearest the heatsink. If this is correct the board was supplied with the link in the clear data position which seems strange to me.
Thanks,
Paul

Jbat1 is the clear cmos jumper, to clear cmos just shift the jumper to 2-3 and remember to switch back to 1-2 after you have clearing cmos, alternatively you can also remove the cmos batt
By default the jumper cap should be at pin 1-2(keep data) if no one has messed with it

[Athlon64] Clear CMOS Jumper orientation ???

I have a new MSI RS480M/RS482M Motherboard and the clear CMOS pin orientation is a little confusing. With the video connectosr and other connectors at the rear you normally count left to right, top to bottom, but the jumper came on the pins on the right side which would be pins 2 & 3 and in that case means "Clear CMOS". Which means of course if I boot that way I'll damage the motherboard. Since the numbers are not printscreened I can't tell which pin is number 1 so I'm not sure how to jumper it for "Keep CMOS Data"? Any help appreciated.

Thanks for the reply Foxbat. Yep .... I understand that. I guess my question is: Which pin is number 1? If you are looking at the pins from the left side of the motherboard the pins would be vertical and top to bottem would be 1,2,3. However, if you are looking at the pins from a position that all the connectors are in the back (video, com, audio) then ... normally (going by all the old rules - left to right, top to bottem) #1 would be different, the pins would be horizontal and #1 would be on the left side and just the opposite. So it depends on how you position the motherboard when you look at it. Looking at pin #s that are printscreened (the ones that happen to be numbered) there is no consistent method of numbering .... and I cannot see any numbering on the CMOS pins. Thus my dilemma.

Black screen Presario CQ62-219WM Clear CMOS jumper pins

About 2 years ago I bought my son the laptop for school from Walmart new. 6 months later, he brought it back to me from his Mom's and said it quit working. At that time, to check it out first, it booted to the HP screen only. Tried to get into the BIos with F2 but it was unsuccessful. Did the usual hard rested sequence with battery out,->unplug adapter-> Hold power button down 1 minute -> reboot with battery only and then with adapter plugged in. No change. Removing the RAM modules didn't make a difference. I replaced both Memory card to 2 GB X2 . Still wouldn't boot. Removed the HDD and replaced it with a known working drive from another 64 bit Wndows 7 OS and that didn't work. The original HDD is readable because it worked in the exchange. As a last resort, I built an Ubuntu live USB put that into the USB port on the presario (32 bit Ubuntu) and no success either. Can't reflash the BIOS. I decided that before I do anything more I would just take it back to Walmart as it was less than a year old and was directed to do so by HP (return it to where it was purchased). When I did, I was informed that because I was concerned of a motherboard problem, it was not covered under warranty and I was essentially stuck. I was recently unemployed so that was it. Went home, read some more and looked at the board and the capacitors visually and nothing grossly abnormal. I tried clearing the CMOS only by removing the battery and cold storing it for 24 hrs. Replaced it and still nothing. Read about the jumpers to CLRCMOS but I have looked on both sides of the board And there are no free pins, and nothing that Identifies anything to say clr CMOS or a variation of that. He wants to have his own back even though it has been a valuable learning tool. So .... Do you have a final suggestion other than go on eBay, buy a new board for $90, and quit trying to fix an unrepairable problem? He's going back to school and I still am out of work. Thank you in advance for any help you can give me.

There are no clear CMOS jumpers on the board. My best suggestion is to use one of the motherboard repair services on eBay. They can identify and repair defective chips on the board using advanced equipment. If you can remove the board and ship them just that, I have seen the service for as little as $70. Obviously you can handle removing the motherboard.

I have no affiliation with this person and there are several other similar ones on eBay. Most of the used motherboards you get on eBay have had a procedure like this done to them anyway.

Clear CMOS - without moving jumper/pins

Thinking about trying to OC my 3000+(W)@Neo2.
My case and eq. in genreall makes it hard to clear CMOS the "old way", and I remember someone telling of a keystroke one could do under reboot to clear CMOS.
How can I do this on the Neo2 and what are the dissadvantages?

Quote
Syar2003
If "Ins" Key is held down when powering up , system starts with reduced fsb and other safe settings . Making that clear cmos jumper uneccesary when OC has gone bad.
Note ! It must be powered off and powered on with the key pressed (just restart key + "ins" wont work).

Clear CMOS did not reset BIOS Password

OK please read my whole post before telling me to try something I already tried.
I have a somewhat unique problem.
My system:
MSI 870A-G54
AMD Phenom II x6 1055T
Windows 7
I have a system password setup through BIOS. Every time I reboot I enter the password. I have not forgotten my password.
I was having an issue getting into the BIOS, I would push Delete and on the POST screen it would say "Preparing to enter Setup" then the system password would prompt. I would enter it and then Windows would boot, no BIOS setup.
This happened over and over. I got fed up and decided to nuke the problem. I powered down, unplugged and set the clear CMOS jumper, waited about 20 seconds, reset the jumper, plugged in and powered up.
Then I pushed delete again, POST returned an error "CMOS not set, date and time wrong, press F1 for setup F2 to load defaults and boot.
I Press F1 and there is the password prompt. Only now my password doesn't work. Enter (blank) doesn't work.
So a clear CMOS again, only this time I pull the battery out too.
Same result.
So I pull out the battery and set the clear jumper and wait 1 hour.
Same result.
So I set the CMOS clear jumper and boot the system (yes I know the manual says not to do this) Obviously no post, 1 minute later I reset the jumper and reboot.
Same result.
So I download the MSI HQ BIOS tool and flashed the most recent BIOS, clear CMOS.
Same result.
My system works fine and I no longer have to enter a password to boot to Windows, but I am locked out of BIOS.
Please tell me there is a solution.
Thank You

Got it! Was doing it wrong way leaving all spaces blank but it doesn't work because it always prompts you to enter your current password; so that's Current Password > "your current password" hit enterNew Password > "leave blank" hit enterConfirm New Password> "leave blank" hit enter and it prompts you to "CONTINUE with save changes?" > hit enter and Password changes from <SET> to <CLEAR>; SAVE & Exit and it's done. Thank you!

How to clear cmos with jumper method MSI Z97 Gaming 9 AC

no have socket for jumper/clear cmos ?

Quote from: pegadroid on 13-August-14, 18:37:12
ok. thank you all. now I'm not confused, I think its socket to clear cmos lost
If you mean the jumper no it did not come with one, nothing was lost. Older MBs had 3 pins for JBAT1 and came with a jumper and it was stored plugged into pins 1-2 and to clear CMOS it was moved to clear pins 2-3 and then moved back to the store position pins 1-2.

CMOS jumper - to leave clear or not ?

I had a major disaster with my P4 2ghz computer, and have not a clue why I get nothing whatsoever on my monitor. At first I thought it was the graphics card. But thats buzzing away as it always has. I thought it was the cpu, as I had to take out the HD and needed to take out the cooler to do get at it, and in doing so some of the pins bent. I thought I had sorted it, as although it refused to boot up, due to some problem about active partitions on the other HD I had, it still got something on the monitor. Only after having to remove the cpu to put in a new HD, nothing whatsoever came up. So after I had originally thought it may be the card, I bought in an MSI KM3M-V, not state of the art but enough until next year when I intend to replace my computer. I have an AMD XP 2000+ and intended to use the old memory (2100) from my old board, which was also MSI made. (Wont make any difference that the board was a pentium board will it ?)
Anyway, I noticed that someone had said something about how the "CMOS jumper" is set to clear and should be changed for the thing to start. Only he said nothing about HOW, or where the damn thing is ! Can anyone help ? I am a complete beginner.

I had no intention of doing anything so barmy ! Where d'you get that idea from ?

No signal after clearing CMOS

Hey,
I was having problems and so chose to clear the cmos (using the jumper). Now there is no signal on monitor!
Just to make sure that it was cuz of clearing cmos, I had another computer with the problem so I did it to that one too lol. And that one also now shows NO signal on monitor. The monitor is working I've tested it with other comps. The picture was showing until i cleared cmos.
the two motherboards I have the problem on are:
MS-7267 Ver: 3.0
PM8M3-V H
Any help is appreciated. Everything is powering up, only thing is that nothing shows up on the monitor, and the monitor is in the "stand by" "yellow light" state.
Thank You

sorry to hear you got double wammy from your mobo but be frank with us did you turn the power off before changing the jumpers setting or 240volt to power supply was still connected on both occasions?? if power was connected you might have caused some damage to your mobo?? lets hope not.
try this if you have time and patient.
1-unplug the pc.
2-Remove all memory and insert only one in the slot1 which is closest to cpu. if you can try to interchange the memory if they fit.
3-change the jumper setting to position where it clears the cmos and please leave it for at least 30 second and not ten. then after 30 second put the jumpers in the original position (make sure you get this right).
4-then plug the pc and power it.
there are occasions where static charges do prevent mobo from working. it has happened to me, and i thought that i had lost the mobo yet it worked a few days later??
lets hope this gets you going.
good luck
p.s do make sure you connect the speakers to mobo, from bip bip sound you may be able to tell the kind of fault you have .

Clearing cmos

Hi,
my K7T266 PRO (ms-6380) went dead after installing a new cpu; four red led's are shown and the old and new cpu won't do a thing... I understand by clearing the cmos there would be a chance that everything will work again. I read the user's manual and understand how to clear cmos but I don't know what this mean. Can anyone tell me about it ? Which information will be deleted ? ?(

look again into your manual,
just at the first pages with the layouts of YOUR board.
i have a k7t266 pro2 and the jumper is under the battery and above the sys-fan-header.
the way of resetting CMOS (BIOS):
shut down Windows/system,
turn off the mainpower switch (behind the power supply),
then take out THAT jumper AND place that one pin higher.
(jumper will cover the 1st and the 2nd pin)
after 2 minutes,
put the jumper back to his ORIGINAL position.
(jumper will cover the 2nd and the 3rd pin)
then turn on the mainpower switch and power on your system.
PLEASE look into the manual FIRST!
P.S. after doing that, you will be prompt to go to the BIOS or load the BIOS defaults.
choose the option to go to the BIOS, because you will have to set up the settings for cpu and RAM, AGP etc...

Clearing cmos in k7n2 delta ilsr

guys, i think i broke my ilsr... i accidentally removed the jumper from jbat and booted my system. all i got was a continuous blinking of keyboard leds.
how on earth did that happen?
well, i was connecting the hard disk that i got which is placed just beside that jumper. maybe while i was inserting the cables, i accidentally snapped it out...
on page 2-30 of the manual, it says:
You can clear CMOS by pressing 2-3 pin while the system is off. The return to 1-2 pin position. Avoid clearing the CMOS while the systemis on; it will damage the mainboard.
the question is, is clearning cmos the same thing as leaving jbat unshorted?
actually, the system still boots, but i cannot do 3d apps anymore as well as intense microprocessor computations. my system just locks up...

Could have damaged the board. I would flash to the latest or back one version to see if you can regain stability, otherwise it may be RMA time.
Good luck.
yup yup yup, that's exactly what i am trying to say... no jumpers in any position (jbat does not have any jumper)
my board is damaged! :angryfire:darn
i tried flashing, but i did not regain stability...
rma time i guess... i just brought the board back to the shop and i asked for a replacement. too bad they ran out of stock... now i am back with my old kt3 ultra2...
- how careless have i been!!!

Clear CMOS ?

hello,
i'm gonna boot my pc for the first time, but not everything is installed yet, the hard drive, floppy drive and CD-RW aren't installed yet... . But still this is a very important first boot, because this way you can check the CPU and memory and graphics card, if they are installed properly and have them excluded for future troubles. my question is:
shoul i clear the CMOS (using hte onboard jumper) before booting it for the first time ? just to be sure there won't be any unlogical settings...with the consequensce that it won't boot...so clearing CMOS should be the right thing to do, right ?
thx
greetz

Hi hypetraxx,
No harm doing so Go ahead and clear 1st before installing anything as this is just a play safe method, in case your mobo have not got it cleared, but situations like this are uniquely rare
I usually don't bother to clear it before installing anything... :P but hey... everything still gets installed and works out fine and rock stable... :D!!!
All the Best... :D!!!

Clear Cmos KT4V-l

hi
i know i should use the jumper but it doesn't work
i even put out the battery still no success
any suggestions ?
pc won't boot i would like to see the message
bad cmos checkpoint press F1 of delete....
thanks !
due to a bad monitor the pc won't boot anymore
i think it did a bad voltage to the main board
now i know it because with my other main board
i got the same situation but there i could clear the
cmos with the jumpers.....
thanks for your replies ! ! !
(sorry for the bad englsih......) )

ok i'll try it tomorrow evening !
but i had the same problem with another mb and there i could solve it by clearing the bios
i ones let me tell that you can do it by sorting someting
wrong at the battery that would give me bad cmos check
but i don't know anymore how since the jumper for clearing cmos doens't work anymore
i even going to try the proposal of wonkanoby
one to success ? ? . . .i hop so almost one month and the board worked 1 day

How to Reset BIOS/Clear CMOS of an HP Pavilion 500-111ea

Hello,
I was trying to change my computers boot logo because i dont like the HP one, and now when i try to enter my bios i get beeping, can anyone tell me how to reset the BIOS/Clear CMOS, this will be much apreciated. The computer still works fine, i just cant enter the BIOS or the UEFI Firmware Settings thing. When pressing F10 at boot up the computer beeps 8 times
My computer is a HP Pavilion 500-111ea
Regards,
Kieran
<I posted this in the wrong selection a few moments ago, i hope this is the right place this time.>

Hi,
Please explain in detail what changes you made in an attempt to change the boot logo.
HP did not post a clear CMOS procedure for your model PC. Review the below image. Unplug your PC, hold down the power button for 1 minute. Now open up your PC and move the jumper blocks over to the left per the image for 30 seconds and then move the jumper blocks back. Plug the PC back in and give it go. If you still get the eight (8) beeps then you could try a ROM image recovery.
Eight (8) beeps in an invalid ROM image. Review this HP posted article for trying a BIOS recovery.
You might try this HP tools software. Download the software to a different PC and create the USB 2 bootable tools flash drive. If you can get the flash drive to boot up then look for a firmware management selection. There is not any documentation available on how to use this function so you are on your own. HP Support might be able to assist you with a BIOS recovery and/or you might be faced with sending in your PC to an authorized HP repair facility to have the BIOS reflashed.
