PC in re-set loop + CMOS problem

Question: PC in re-set loop + CMOS problem

Hi there,Hope someone can help?.. First problem I had related to the PSU not working properly. The PC kept cutting out on start-up, it was only after pressing the start button/re-set button several times that the PC managed to finally get to the desktop. This problem has got worse and a few days ago during the usual dozen or so attempts at trying to get it started I noticed an error on the first start-up screen (the one where it does the memory check). The error message was:-?CMOS checksum error ? defaults loadedF1 to continue. Del to enter setup/Dual Bios, F9 for xpress recovery08/02/2004 nvidia-nforce-6A61BG0MC-00?I took the F1 option and it got as far as the windows logo appearing with the scrolling progress bar. The pc then did a re-set by itself but this time there was no cmos error message. However it again did the re-set at the windows logo. So it seemed to be caught in some kind of re-set loop. I switched it off at the PSU as this was the only way I could power it down.The next day I couldn?t get it to power-up at all. The PSU had packed in I guess.I replaced the PSU with another and on start-up it went into the re-set loop again.After a bit of research I replaced the cmos battery from my other PC and tried it again. This time the old CMOS error appeared but this time when I took the F1 option it loaded up windows without any problem. However the processor speed is not appearing correct in the device manager, but I think I know how to fix this in the BIOS/mobo. Unfortunately when I now re-start the PC it goes back into the re-set loop. The only way I can get the PC to boot ok is by taking out the CMOS battery and putting it back in. This only works once and after a re-boot I need to do it again.I am actually using the pc now to post this, and it?s been working ok for about an hour, but I know if I re-start I will get the re-set loop problem.Can anyone offer any advice?Thanks in advance.IanSorry for the long post.

Preferred Solution: PC in re-set loop + CMOS problem

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Answer:PC in re-set loop + CMOS problem

what are the specs of the machine? the psu?

try updating your bios and all device drivers you are using, particularly those of the chipset and video card. a PSU that failed as such could have caused data corruption in the ram, which could have corrupted files on your hard drive. also, there is a possibility that the hard disk is going bad.

whenever i get a machine that behaves this way, i boot to my copy of knoppix (on CD-ROM) and run memtest. if that passes, i boot knoppix. if everything runs fine, you should suspect the hard disk. knoppix is available at but before going through all that i would use memtest. (

is the hardware being properly detected in the bios? everything come up, as it should?

I have a failed upgrade to Win 10 and then downgrade to 8.1 which is giving me problems. Currently the laptop is stuck in a boot loop where the BIOS starts and looks for something to boot to, gives a "please wait" message then shuts down and starts over again.  Hitting any keys (F2, F12, F8, F11, etc.) does not do any good.  Not sure if an external KB would even help.  I have tried creating a bootable rescue DVD (from another computer) with no joy.  Tried a couple of of bootable USB keys, also with no luck. Have tried removing, reducing memory to force a rejog, switched drives (I was using the old OEM drive and not the bigger one that I normally use).  Tried removing the CMOS battery for over an hour, also with no luck.   Took it out and am waiting to see if it erases.   I have also tried holding down the power button with AC and battery out. ANy other suggestions? This must be a special "temporary" set up for installations but now the machine is stuck!

I tried various Win8/8.1 install DVDs ut to no avail.  It'd read the disc for a while but then restart and go into the boot loop.  Eventually bought a new MB. FWIW, the 5560 does not have UEFI so I doubt that was the case.

Every time I turn my desktop computer on, the fan immediately starts running at 100% and won't stop. And, for example, I shut down the computer and went on a three day vacation and when I turned it back on it was immediately like this, so no, this is not a case of overheating.
I have to sit there a play with the computer - usually do several hard shutdowns (which is bad, I know) before I can restart it normally and have it not do that. When it starts up normally, it shuts down normally. When it starts up with the fan at 100%, even when I "shut down" the computer and all the lights go off, the fan still runs!I tried following the instructions on the last post of this page: but I can't even complete them because the back of my computer does not look like that diagram (do I have to remove the metal frame or something?).This is a work computer, we have no IT department, and I don't have all day to work out the problem since I have to, you know, work.

This is only happening about every 10 tenth time I start the computer. When the computer is turned on, a message is displayed (white text and black background) that the "CMOS/GPNV Checksum Bad, CMOS Date/Time Note Set, Press <F4> to Run SETUP".
Windows XP is started and the time for the computer is set to January 1, 2002 01:00AM. I can manually change the date/time in Windows to the correct time. However, this is happening only occasionally. How can I prevent this from happening?

Hi This machine is less than a year old, and has started generating problems on booting.   At first, the problem related to the CMOS (Error 0192 on bootup I think - I don't have the error message to hand) - so I replaced the battery. This worked for a day or so, and now I get 0232: Extended RAM failed at location 1F  I can save my setup to the Flash BIOS so it boots past the message, but now it runs so slowly that it will not actually boot up Windows in a finite amount of time. Any suggestions on what to try next? many thanks anthony

I had to take out my battery then went into the CMOS setup utility then I loaded the optimized defaults, now I need to know Do I save the CMOS to the BIOS or it asks me if I want to Load the CMOS from the BIOS?? What's a girl to do? (smile)

Answer:should I save CMOS to BIOS or Load CMOS from

Defaults are just a starting point (or fall back point if you screw up) & are generally not the best performance settings, even though there is an option to load "optimized defaults". It would be nice to know your system specs (motherboard, CPU, RAM, etc). If you don't wanna get into customized BIOS settings, simply click "load optimized defaults", then save & exit.

Question: CMOS problem?

Hi All,

My folks computer began forgetting the time and BIOS settings so I just assumed it was the CMOS battery (it is 6 yrs old) and replaced it for a new Energizer CR2032.

It seemed to work except for when the system was put into S3/STR and later brought out of standby the there would be no picture on the monitor and it would not shut down. So since then we have avoided standby and just shut it down.

However this evening it has begun forgetting the time again and the new CMOS battery is only 2-3 weeks old so I was wondering whether the CMOS has had it on the motherboard.

Could anyone shed any light on this?

The system in question is a MSI 648-Max Mobo, 2.4GHz P4 Northwood, 1GB DDR400

Question: Cmos problem

I have a Gigabyte GA-8simlnf board with p4 2.7 GHz chip on it.
Every time i started the PC, it would switch on, but no VGA signal came on screen. I would have to hold power button in for 10 secs to turn off and then the next time i turn it on it works. I firstly thought it was the ATI AGP Card, so i replaced it with a different card but no difference. Tried a PCI grapics card and it did not get any signal at all. SO then i thought, maybe if i remove the CMOS battery for 30 secs it may clear the bios as maybe there was problem there. I had the power plug in during all this. Now i get "CMOS/GPNV Checksum Bad" message on bios screen when pc starts up, it says i can press F1 load defaults & Continue to change values and F2 to Setup. f2 does not take me to Bios and when i press F1 all that changes is were the message above also savys F2 : Setup F8: Boot Menu, it changes to F8: Boot>Network.
This is very frustrating, i would appreciate all the help i can get. thanks

Answer:Cmos problem

Read this link and follow the guidance therein - and for heaven's sake, when tinkering inside your comp, pull the power plug and make sure you are electrostatically discharged first.

It is also recommended that you hold the power-on button in for a few seconds after pulling the power plug (so I have read and do).

I have a pentuim3 with a gigabyte m/board.
Everything works fine without any problems.
When I want to change my boot order under the advanced tab in the cmos it only says:"View DMI event log"
Then it just goes back to the main menu.
Can anyone tell me how to correct this problem.


Answer:Problem with the Cmos

Several thoughts...

(1) The setup screen (and the CMOS) is a function of the BIOS - not the processor or the mobo. Different BIOS chips have the boot-device pick-list in different areas - you might find it someplace else. Otherwise, you will have to find and relate to us the exact maker and level of your BIOS (it should flash on the screen when you first power on).

(2) The boot-device pick list can only be populated with devices that are "eligible" for booting. Some devices which the BIOS recognizes and can deal with are simply not eligible to be boot devices. Sometimes, devices need to be set (marked) if they are going to be allowed to be boot devices. And, finally, some BIOS versions simply will not support booting from every device in the system (usually the more exotic devices like Zip drives and even some CDR's or CDRW's).

** I have seen cases where computers that are "inherited" from a corporate environment will act like yours. This is usually because the corporate Tech-Support folks have gone into the BIOS and disabled CDR's and Floppy drives so the employees will not be able to boot strange things and corrupt the machine or import a virus.

Question: CMOS Problem

I can't get into CMOS because I don't know the password. I heard that you can correct the problem by a temp. removal of the battery and clearing the CMOS. When you remove the battery from CMOS/motherboard and it "clears it." What does that mean? Does that mean all the settings are gone? Are there default settings? Will the PC still boot up? Or is the password restriction removed?

On the same PC, it has been booting up to CMOS. It has stopped doing that and now it is not shutting down completely. What does that indicate? Motherboard going out? CMOS trouble? What can I do? Please help.


Answer:CMOS Problem

Ok, calm down, that's a lot of questions.

Let's try to address getting the CMOS cleared first. By taking the battery out, it's going to clear what the computer remembers about the password, time and date, and the hard drives. (P.S. unplug the computer when you take the battery out, and ground yourself by touching something metal as not to short anything out).

The good news is that there are default settings, but what you'll be doing is going back into the CMOS after you've put the batter back in, and allowing it to refind the drives, and set the date and time, etc.

That's all my brain can handle right now.

I've been working on making a new machine for a friend off and on for a month now and it's driving me nuts. I've made several before, I don't know what's going on this time but I can't even get so much as a beep out of the motherboard.Right now I have:Soyo SY-K8USA DRAGON Ultra boardAthlon 64 2800+ (also have a AMD Sempron 3400+ that acts the same)Right now if I power it up, it does nothing. The LED on the MB comes on, that's it. If I take the battery out the fan spins, no beep or anything, the case speaker is plugged in correctly.. If I power it up with just the processor, shouldn't I at least hear a beep? If i reset the cmos jumper, the fan turns, put it back in place when the battery is in and it stops again. I've tried a fresh battery and it does the same thing.  Anyone have any ideas?

Sounds like a MBoard short to me...pull that board and set it on a rubber mat on your desktop...hook up only RAM, CPU and the vid card and power up...if you get no beeps either the MBoard or the CPU has gone south.If you do get beeps congratulations the above doesn't apply.Introduce 1 component at atime until you find the culprit.

Nothing appeared on the screen and no noise came from the hard drive to suggest it was starting.Someone suggested resetting the CMOS/BIOS, so I browsed the net till I found details of a similar board by the same manufacturer and this indicated which the CMOS reset jumper was. I moved the jumper, then returned it and restarted: everything burst into life and all was well. I say WAS because it has all just stopped again.The symptoms are the same as before, but moving the jumper now is having no effect.Was I lucky last week or was I right and there is something more serious wrong now.

hello... i am new to this post, but i am not new to computer repair, so i pose this to my fellow community members.
a friend of mine brought her cousins latitude c600 to me to repair,for the cousins son had a password on the computer, but could not remember it. immediately i see that it was not for the os, but for the cmos pw. my initial reaction was that a minute fraction of 10 year olds would even know what cmos is, an even fewer would find cmos and set a pw. am i in the minority in thinking that, or not? and of course the cousin is not the original owner and hassling w/dell over ownership, i will leave for the cousin.
what percentage of passwords were set by children? or were a lot of these models, and similar others, dumped on other buyers, or were bought from crackheads or other nefarious sellers and now many people have useless laptops.
i truly became concerned when i went to two of my friends that repair computers also and they have dells that were brought to them to repair with the same problem, and i live in a very small town.


Answer:How prevalent is this cmos pw problem?

Well according to this post, I'd say thousands have similar issues.
As for kids (possibly) putting passwords on. I'd say it's more likely that these were (mostly) corporate laptops, that had the harddrive wiped, but the password was left on.

I changed the battery 3 days back but again after a day I again started getting the same notification of changing the battery.

Pls tell where could be the problem.


Answer:CMOS battery problem

Was the battery you replaced the bad one with brand new? Also make sure it is a 3V battery and to be safe, make sure it has the markings 'CR2032" on it (that is what mine has). Other batteries of the same size and voltage MAY be fine, but I can't really vouch for them. Also, if you have one, it might pay to check the batteries voltage with a multimeter.

Also, if you buy a new one, it might pay to make sure that it is meant for a computers motherboard, as some may or may not be, just to be on the safe side. I don't really know a great deal about these batteries.

Answer:BIOS and CMOS problem...

The BIOS has to be installed, if it isn't your computer won't function and there's no way you'd be able to get into Windows.

Have you tried entering the BIOS? If you can't you should try clearing the CMOS, and you may need to flash a new BIOS depending on the situation.

Hey all, been a while since I've been here.

Today I started up my computer and I get a message "CMOS Checksum Bad"

It asked me to load default bios or to configure it myself.

I can seem to find the issue here, I have no idea what's wrong.

I'm on an ASUS MB, model K8V SE Delux with Windows XP Pro Op system.

I weird because the notebook is new and all bios preferences besides date and time are ok.  Has someone  the same problem?Do you have any information about the place, when  cmos batery  is situated? i have T60p.Thans.

Answer:CMOS batery problem

Hello and welcome,Please take a look at our FAQ thread, which includes a link to the Hardware Maintenance Manuals which will direct you how to replace the CMOS battery: you have a brand new system, the CMOS battery shouldn't have gone bad just yet. You can try replacing it yourself certainly, but your machine is under warranty and this would be covered.Message Edited by Tim_Lenovo on 12-12-2007 08:48 AM

ok so i have had my mother board (asus a7n8x-x) and my cpu (amd athlon 2400+) for something close to 2 years. and i am now unable to use my computer. At random my computer started having "start-up" problems. eg

-instead of loading to the first bios screen. it sits idle on black screen (monitor light flickers) and dosnt load until i shut it off.

-loads to bios and tells me that my CPU speed/voltage/or something like that, isnt set properly. So i go into bios set it, save and exit then find that it goes back to the black screen without loading.

the only way i have ever been able to get it past the black idled screen is to turn off computer, swap the CMOS clip (connector thing) turn computer back on and HOPE ! that it gets up to the bios screen, where it then asks me to reset the CPU speed/voltage again. After doing this the cycle repeats.

i dont know what the problem is, i was going to take it into a shop to get looked at but alot of people on here have been right about alot of things before so i thought that i should chgeck it over first.

please help. thanks

Answer:Motherboard cmos ? cpu ? what is the problem ?

Check that the DIP switches on your mobo are set correctly so that they match the FSB etc that is set in your BIOS.

Also try reseting your BIOS by removing and leaving your CMOS battery out for bout 10 mins.

The other thing you could try is to hook your boot HDD to another PC and see if you can boot from the HDD at all.

I just built a computer from the ground up - it works great except for one problem.

When I disconnect the power cord, then reattach it (with pc shut down of course), and reboot, the cmos settings are cleared.

However, if I shut the computer down, but leave it plugged in, and reboot later, they are maintained.

Does anyone agree that this is a cmos battery problem, or could it be something else?

Running an Advent 2.2 then my Audigy Sound card got blown through a lightning strike! When I tried to replace it I now get an error message on booting up Error 251 CMOS checkdigit does not agree reverting to default config. Can anyone help

Answer:CMOS Checkdigit problem

CMOS error 251 shows that a memory module has failed. Your lightning strike may have done more damage than you think. Try reseating your memory modules and reboot. If it fails again, remove DIMM 2 and reboot. If that fails remove DIMM 1, replace DIMM 2 and reboot. Try them individually in other DIMM sockets too. If you can, try them in another mobo (a friend?).If no luck then you may need to buy new RAM - or even a new mobo too! First on your shopping list should be a surge protector strip for your PC and peripherals.

I am experiencing 'weird happenings' with my computers BIOS.

I bought my computer from Holly System, it has a Chaintech motherboard and phoenix-AwardBios - Bios. I cannot refer the problem i have too Holly System because they do not exist anymore.

Two or so years after purchasing my computer, i turned my computer on and was hit with an error message on boot, 'CMOS Checksum error - Defaults loaded', when the computer fully loaded up i noticed the time and date had changed, the date had gone back to 2002 and the time 23:00.

Forever onwards i just got used to turning the computer on being given the CMOS error and then repeatedly setting the computers time and date. Eventually i decided to look into the problem.

Hi All,
I have a very unusual (at least to me) problem with booting the computer. It wouldn't start so after checking all the other possibilities (hard drive, power supply and video card) I decided to pop out the cmos battery and throw a new one in. This is a 2 yr old Gateway so I didn't go there first. Well, lo and behold it started and everything seemed fine and I went in to the bios and set the proper date, time. The next day it would not start again. I opened it up and and popped out the cmos battery and reset it and it worked again! I changed the date, etc again, and ran a virus scan and can find nothing else wrong. Has anyone run in to this before?

All ideas are greatly appreciated.

Question: cmos/boot problem

Hello allI just upgraded my gfx card - a nvdidia 7800gtx to a 8800gt. Yet I couldn't get my system to recognize it. I'd read that there have been some compatibility issues with this card and earlier mobos - mine is a Abit kn8 Ultra - and on checking saw my BIOS were very old. So I cautiously went about the BIOS upgrade/flash process. But I never even got that far. I followed the instructions from the Abit website, made a bootable floppy, then to this added the BIOS upgrade/flash files I'd downloaded. Then I went into BIOS to change the boot order to floppy first. But, all of a sudden, BIOS demanded a password - even though I'd never set one, and I'd got into the BIOS screen before and never been prompted for one. I tried some backdoor passwords but none worked so I reset the cmos by repositioning the cmos jumpers for a few minutes. After that, I replaced the jumpers, turned on, got into BIOS without the password prompt, set to boot from floppy first. Restarted, but now I get a 'disk I/O error hit any key error'. Then when I tried to boot from HD again I get a 'disk read error press cntrl, alt delete'. So I can't even get to the BIOS flash stage or even into windows! Why is it not booting from the floppy? I've never had problems with the drive, and I checked that all the necessary files were on there. And why won't it instead boot from HD either? Has resetting the cmos caused it to not see the raid config properly? Any ideas anyone?

Answer:cmos/boot problem

If you've reset the CMOS you may now have incorrect settings for floppy and RAID - so recheck the BIOS settings.

First make sure the computer is off. Then take out the battery. Next, move the jumper and wait at least 30s. Move jumper back, put battery back in and then power up.

I've seen a few problems like mine on the boards but never a satisfactory resolution. My problem started with a frozen screen. I did have a few windows open and i was listening to music and surfing at the time. Upon restart case light came on, M/B power light came on, fans on psu, cpu and graphics card all spun up as well as hard drive, but no post beep. Long story short is that I have done everything recommended on various forums, like resetting the Cmos via the jumpers, taking out the CMOS battery, leaving the CMOS battery out overnight, new CMOS battery, changing the PSU etc. and am now at the stage where I have the M/B stripped out of the case on the workbench with just the psu, one stick of memory, Graphics card, Hard drive, mouse and keyboard. Strange thing is computer WILL post with default Bios settings when CMOS battery removed, go through bios setup routine, launch Windows and run perfectly normally. But as soon as I put the battery back, nothing, no post beep, nothing, just spinning fans and no display. Has the Bios Chip got corrupted? The battery clip does look firmly soldered to the M/B and is not bent. I am at a loss. Can't RMA the M/B as its an Ebay job. All the Caps look sound. Is it worth replacing the BIOS chip as they're fairly cheap or is the M/B toast?? Does anyone know anything elseI can try??

Hi guys,

I'm new on forum procedure, so please bear with me if this is in the wrong place.

My desktop is a predator from Power Computing running an AMD dual core 3,800 2.01 GHz on a Asus A8N-VM CSM motherboard 960 MB RAM.
The software is XP Home with SP3.

I replaced the CMOS battery recently because it had run down. Everything went smoothly,I rechecked the bios, everything ok. the computer booted up and started ok, but with one exception; I had lost the post screen.

Normally, when the system boots it presents the post screen options on the monitor, but now it starts with a splash-screen from Asus, The Asus screen gives the option to press del or F8, I feel this is an unwanted intrusion, but I don't know how to get rid of it and return to my normal post screen.

Any suggestions out there?


Answer:Problem after CMOS battery replacement

Typically...there is an option in the CMOS settings...something called "quick boot" or whatever...that determines whether you see the POST check or not. Take a look at your current BIOS settings.

I have an HP Pavillion ze4900 laptop only about a year old that will not keep the accurate time when it is turned off. It also seems to lose settings for some programs (bookmarks in the web browser and passwords and settings in other programs). It keeps good time while it is on but resets back to 12 a.m. Jan. 1 2004 after shutdown, so I don't think its a problem with the real time clock. I checked with HP Support and they recommended a bios updgrade, which I did. I even did a clean reinstallation of Win XP Home Edition SP2 but neither solved the problem.

We've had this problem ever since we got the computer. I suspect it is a bad cmos battery and I've read elsewhere that its not uncommon for these laptops to come of the assembly line with bad cmos batteries. Does this sound right?

I've changed cmos batteries in desktops but not in a laptop. I downloaded the service manual but there's nothing in it about changing the cmos battery. I believe I read somewhere that you need to remove the keyboard to get to it. Once the keyboard is out is it just unplugging the old battery and installing the new one or do you have more parts to remove to get to it? What should I expect to spend for a new cmos battery? I haven't had much luck finding any on the Internet.

We have about three weeks until the warranty is up, so should I just send it back to HP and hope they can fix it? Thanks in advance for your advice and suggestions.

Answer:cmos battery problem in hp laptop?

Good Morning Bob, these batteries should last at least eighteen months, although your description would appear to be a battery problem it is a little premature.
There is a possibility that some element of the clock and CMOS circuit could have some problem and is using excessive current thus producing this effect.
Some of these battery holders also can break when an unknowing person tries to remove a battery, some can be quite tricky.
It would therefore make more sense to return the machine for warranty repair.
Cheers, qldit.

Hi this is my first post so I apologise if I don't do it right and please bear with me :)

I needed to clean up my computer as its been used for absolute crap over the past few years so looked up how to erase my hard drive, got the xp disc off a mate then went into my bios settings and told it to boot from cd BUTTT i must have accidently set the secondary to boot from the wrong hdd and i don't think i set a third.

It then didn't boot from my cd for some reason and ever since I haven't been able to get it to so I looked up what I should do. Found out the best way to sort it was to reset the CMOS so I tried removing the cmos battery which didn't work, then tried what I thought was the 3pin jumper and still it didn't work.

So being frustrated i tried the jumper next to it, it still didn't work. Obviously I was getting a bit annoyed by this time and my problem is that my computer still wont show on my monitor when it starts up and I'm now not sure if the jumpers i moved are even in their correct positions.
I'm not too sure what system things to put down but I'll put down what I can.

Computer runs xp
I believe the bios is phoenix.
I believe the motherboard is MSI.
I don't particularly know where to find everything else.

I went on vacation and came back four days later to find that my computer would not start. Pressing on the power button did not do was simply dead (no spinning fans, HD, etc.). At first I thought that maybe my PSU or some other component got fried because we had a brief power outage/brownout the day I left for vacation (the computer was running at the time). However, it was hooked up to a UPS and to my knowledge the computer never lost power/shut down unsafely (I was able to use and shut it down normally after the brownout). Also, when I opened the case I saw that the motherboard LED was lit just fine whenever the computer was plugged at least I knew that the PSU was providing power. I checked the power button cable/connectors and also found nothing wrong.

After some further experimentation, I discovered the (temporary) solution: I must take out the CMOS battery and leave it out in order to be able to start the computer. Otherwise, it simply refuses to start. I find this very strange since CMOS battery problems usually lead to loss of BIOS and time settings but never have I read a case where the battery itself was preventing the computer from starting up. So right now the computer is running fine...just as long as I leave the CMOS battery out.

Hi I've run into an issue with my CMOS. I'm using a Lenovo Y40-70 and the CMOS version that is currently installed is 99CN28WW(V1.11) and the EC version is 99EC28WW(V1.11). I had read somewhere that when you start to have problems with the CMOS you should flash it or update it. I tried that and got the following error message: The version of ROM file is the same as that of BIOS.This is true as I checked that the latest update for CMOS is 99CN28WW on the site. So here is my problem... My system is losing the date & time when I shut it down. For instance if I shut the laptop down at 7:40PM on Jan 1, when I boot it up the next day it will still be Jan 1 at 7:40PM. I have to manually go into the CMOS and change the date and time everytime I turn the laptop off and turn it back on. If I do not turn it off, it is fine, but I prefer to turn it off when I'm not using it. I've read that the best way to combat this type of CMOS problem is to install a new CMOS battery.  My question is how do I go about doing that? Do I need a special setup for it? The reason I aks is because I bought a standard CMOS battery at a local store and when I opened up the laptop the CMOS is actually in a black wrapper. When I unwrapped it there were two connectors on the battery itself which leads me to believe that perhaps I need to buy a specialized battery with the connectors already installed. Is that the case? If so where do I get that? If not how do I get those little connectors ... Read more

My MO-BO is a Gigabyte 990FXA-UD7, and I've noticed the CMOS display is showing FF. If there is a 'h' after, it's blocked by my graphics card.The MO-BO manual states that FF or FFh is "Boot attempt (INT 19h). It doesn't explain what that means. Cheers, In advance =)Now, this board has an onboard Reset Switch (RST_SW) and CMOS Switch (CMOS_SW). The manual says the latter clears CMOS values.So, what does 'FF' means exactly, what could have caused it, and does it have any negative effects on performance?Build:990FXA-UD7AMD Phenom II X4 925 2.8 GHz (Quad Core)2 x 4GB Corsair Vengeance2 x Gigabyte HD6870 OC

Answer:CMOS POST FF(h?) on CMOS display.

FF is related to 2b and appears to be graphics card related, this was taken from a web page:"2bWhen the system powers on and the Debug LED shows the usual POST code sequence but hangs on 2b or you get a beep code as soon as the sequence reaches 2b, then the Mainboard cant detect your Videocard properly. Note that the POST code sequence might not halt at 2b but continue, so the final POST Code it displays could be FF, 00 or 7F which means the Maiboard booted, entered BIOS, or OC recovery kicked in and is waiting for Input to enter BIOS. Since the Videocard couldnt be detected properly you will only see a black Monitor and either 2b, FF, 00 or 7F. Check if there is something wrong with the Videocard, the PCIE slot or BUS, the Monitor or monitor cable. Turn the Monitor on and off, switch the Monitor cable from one D-SUB or DVI plug to the other in case your Videocard has two. If this doesnt help then reboot and load the optimized defaults. If that doesnt help either try another Videocard if possible, or try the Videocard in another system to make sure its working properly. Try another monitor or try the Monitor on another System."Googling is quicker than waiting for an answer....

After a "move" PC started and mouse did work but keyboard did not. Next day on start-up did not complete and request to press either F1 or F2 to continue (in different modes), but, the keyboard does not work and have confirmed wireless keyboard operates fine. Does this mean a main battery replacement or?

This is a first...

A friend was visiting for three days and a few things seemed to change. He shut off my monitor when not using the PC. It didn't come back on when I hit the power, so I hit the menu button and tried to get the thing up & running. I didn't get into the monitor's menu.

That's the only thing that was done differently. Now XP asks for the CMOS setting every time I boot up. It asks for standard (F1) or advanced (F2). When I do the standard setting, my computer starts back to the year 2002 at 12pm.

How can I get things back to normal, when I turn the PC on and it boots up in XP like always?


Answer:CMOS setting: XP won't boot w/o going through CMOS

If the date changes, chances are that the CMOS battery needs to be replaced. Just a co-incidence on timing and your friend, I'd say.

Hi, i have an anoying little irritation with my pc, hope you can help.Here are the facts:Its over 3 years old nowThe mobo is an Asus A7V333The problem started the same day as i attempted to connect a friends external HDD (USB2) it wouldnt work until i updated "enhanced host controller" then it worked. But in the process it had restarted the pc giving me the black screen with options to "start normally", "start with last known good configuration" i chose the latter.The follwoing day i couldnt get the pc to start, here are the symptoms:On shutting down i need to flick the main back switch to off and leave it at least 30 mins before switching it back on enabling me to start the pc.The mouse light also goes off now when shut down.The latest thing ive noticed (about 4 days later) the clock isnt keeping time when switched off at the back and i get an error when i try to update the time from the net.Ive done a search and there seems to be a connection between bootup problems and mobo batteries going flatDoes this sound like the battery to you?If so, is there anything i should know about changing it, im very able to do it, although ive read that the cmos has to be reset???

Hello everyone, I have an odd problem with my 690. In BIOS it always says that the CMOS battery is low, and it always says the system has shut down due to a "thermal event" (although it has NEVER shut off due to overheating). It also NEVER saves ANY CMOS BIOS information, regardless of what CMOS battery is in it. I've tested 3 batteries and they all do the same thing. BIOS says the battery is low, can't save settings, etc. It even does this if there is no battery in it at all (reporting low battery and thermal shutoff). I am guessing this could be a capacitor issue, or is it something else?

The system's specs:
Intel Xeon DP 5060 3.2 GHz
14GB of FB-DDR2
NVidia GeForce 9500 GT overclocked (650 MHz core, 535 MHz Memory)
160 GB HDD (OS, applications)

I just finished building a new computer with the following specs:

PCChips M916 Motherboard
Pentium 4 2.26ghz Processor
512MB PC3200 Ram
Radeon 9600 Graphics Card
10GB Maxtor Harddrive (Old, getting a new one soon)

Now, I set it up and put it all together fine. When I go to power it on, it tells me my CMOS settings are incorrect, and sends me to the setup utility. At first I tried default values, which apparently did not work. I tried to boot with the default settings, and it didnt work - no picture on the monitor, keyboard doesn't light up, no motherboard posting, etc. So I clear the CMOS via the jumper, and try again. It brings me back to the CMOS setup, and I try some different settings. So far, no matter what I try, it will not work. Given my current system specifications, is there anything special I need to do to get the CMOS settings right? So far I can't really find anything I need to change other than changing the date and time.

Thanks for any help.

I recently installed a new Power Supply Unit. A 420 Watt Dual Fan Chieftec.However, I have a Trust multiple wall socket with an on/off switch. If I keep it on, but turn my computer off, there will be no CMOS checksum error, but if I turn off the wall socket when my computer is turned off, there is a chance of a CMOS checksum error occuringWhat could this indicate? According to this[/url  article it can indicate a faulty or bad BIOS battery. However, the battery is barely less than a year old. I cannot seem to remove the battery, I once had to reset my BIOS and the battery would only be lifted up a few milimetres. This was enough to make it reset, but I couldn't peel it out.It concerns a Gigabyte 7N400 Pro mainboard. Revision 1.0

Answer:CMOS checksum error problem persists

Well, what you're describing is indeed the classic symptom of a bad battery.  You may have bent the battery holder where it's not making good contact.  To remove the battery, it's only necessary to pry the contact up a bit and just push the battery out the open side of the clip.

After renewing the CMOS battery (CR2032) on a PC the following problem has occurred :-

Startup - Normal

Computer operation : Normal
Shutdown : Normal
Standby : Won't go into Standby

Clicking on Standby switches the Monitor OFF but the PC remains ON. There is some ongoing disk activity and then after around 2 minutes the monitor comes back ON and everything is as normal.

I have checked for updates to the BIOS but there are none available.

Before I start messing around with the BIOS settings I am asking if this is a common problem to which there is a simple fix. I have replaced CMOS battery's on many, many computers but have never experience this particular issue.

 I am trying to repair a TP I Series 1721 2627-721(P11 300 /192MB /20GB HD) that will not fully boot on most occasions. It will boot but only after several restarts while pressing the F12 key. When it does the cmos resets to default settings and the system clock reverts to 1/1/1988. I get error messages 0251 (Time and Date error) and 0271 (Default configuration set) as well as a red message stating " save to disk file not found/ save to disk feature is disabled/ run phdisk for info. file: create new. partition: consult manual". If I enter cmos and correct everything the machine boots up perfectly to Windows XP Home SP3. All devices work properly as well. When it shuts down it reverts back to the problem. I replaced the 3volt lithium battery but there was no change. The main battery is dead. I thought possibly flashing the bios to the current one may help. Is there a way to do this with a dead main battery. Any help would be appreciated. Thanks.

hi folks. good day to you all. my name is max. i can install windows and manage basic troubleshooting related to software without any problems. a couple of months back i installed windows xp on my friends computer and it was working fine but a month after installation, when he booted the comp up, he would get the startup options msg (safe,normal and so on) instead of windows booting up normally. when he tried to boot it up in any mode,the windows xp loading logo would just appear and windows just kept restarting. i thought it might be a software problem ,so i made a fresh install of xp and it was working fine . but now once again the same problem seems to have occured. this screen pops up when he starts the comp. i have included the image he sent me (its a bit blurry but you can make out whats on it). i searched about it and as you can see in the image, the problem seems to be about CMOS settings. now, from what i have learned so far after researching about it is that its either the CMOS battery that has lost its charge, died, or maybe its just a CMOS (or bios? not sure) settings problem. can you guys please take a look at the image and tell me what exactly is wrong and what steps i would have to take to fix his problem? thank you in advance.

Answer:Possible CMOS Battery problem with my Satellite 1405-s151


I don't think this is a problem with the CMOS-battery. If it is defective or has a low voltage, the machine will give this error message, BUT it will never have a problem booting up because of it. A defective battery will make the system lose track of time and date and possibly some settings You might have made in the SETUP but when the unit starts and gives the error message (You have to press F1-key to continue) the default settings will be set and they are good enough to make the system boot. I suggest You remove any hardware You might have added to the unit (memory, PC Cards and so on) and try again. If it still fails then I think Your machine is defective and need service.

best regards

Its a packard bell laptop, and the system started to freeze for no reason. No viruses. Now, I can usually only move the mouse pointer-if it lets me start windows at all (xp). As of tonight, the system wouldnt let me even pass the startup screen, it kept asking for a non existent system password to continue! The system bios clock seems to reset itself too, so I believe the whole problem to be related to the cmos battery.

My main question is, how much should I roughly be expected to pay for a cmos battery and installation from a general pc repair store? The laptop is out of warranty, so I dont really want to be spending £30+ just for Packard to find and install one either. The reason I need someone else to do it is because this particular packard system has the most awkward setup, and therefore access to the battery is next to impossible..

there are only 3 panels on the back of the machine that you can remove- 1 hard drive, 2 ram, and 3 wifi card (I think!).. the cmos battery (the circle!) is to the right of one of the panels, under the casing. I have tried removing the entire casing, all screws and connections, and even from the front, trying to get to it by removing the keyboard, but it proved impossible to me, so Id rather get someone else to do it.

But inside the for loop, i have a while loop. I want to increase the variable "i" while inside the while loop:


while (certain condition is true)
{ -certain code-
i = i+1

But in matlab, whenever I come out of this while loop, the for loop ignores the changes to i in the while loop and keeps going from where it was before the while loop began.

Is this similar to what happens in other languages? Does anyone know a way around it?

I have a HP Pav 13 x360 Win 10. The main battery has the CMOS included inside it or it doesnt have one, I have heard both. The error persists with the battery uninstalled, using only AC power.

It all started with plugged in, not charging. Then got CMOS checksum is in invalid on startup. Changed battery 3 times (twice from HP and once from me)

Gave up and set it aside for months. Took it to a tech who could not find anything wrong with it. It was charging normally and told me it just needed to be at 0 for a while and should work fine. It booted with no error.

It is now showing the error again but is charging. Could it be a motherboard error if it happens without a CMOS? I have updated it and flashed the BIOS.

Any help is appreciated
