  I'm cmos-checksum-error-defaults-loaded-error what is the remedy to get it resolved?

  Please guide me in detail for him.

  The first thing to check and change if you do not already have is the CMOS BIOS battery.

  It depends on the type of PC (desktop computer/laptop) and the brand and model. Search the support site of manufacturers for your brand/model of PC for all the guides.

  However, as a rule - http://www.computerhope.com/issues/ch000239.htm no need to download anything, just read as a guide. Note the static precautions etc.

• CMOS Checksum Error Inspiron 570

  Recently, we had a power failure where the power came from top to bottom.  Once the power was restored, I turned on the computer and displays an error message (forgot exactly what he says) but there were two options (I think) F2 and F12.

  I searched online for this error message and it seems to indicate an issue that could be resolved by clearing the CMOS.

  So I removed the battery, set the jumper CMOS clear, waiting 30 minutes, put the jumper back and put the battery back in.   The message I saw was gone, but in its place, I get this message:

  CMOS Checksum Error
  Press F2 to start the INSTALLATION
  Press F1 to load default values and continue

  However, pressure on one of the buttons does nothing as if the keyboard entry is not registered.

  I tried another keyboard - no change.

  I tried a different battery - no change.

  I tried to use a barrette of ram - no change.

  There are no beeps at startup.

  What else can I try?

  Thank you

  You may need to replace the motherboard.

  If the failure was the fault of your electricity company, they pourraient have insurance to cover the repair...

• HP 350 G1: HP 350 G1 CMOS checksum bad 502 & reset

  Hallo,

  I own a G1 F7Y99EA 350 HP, (shipped with BIOS version f.13, via the latest version of the BIOS HP is f.12!)

  Every time after that the power is off (whether it's battery or simply remove the battery) I get the CMOS checksum error (502) with reset. After the reset, everything works perfectly fine, I have to change date & time, otherwise a few software goes crazy.

  I run win7 pro x 64 and my system is in good condition, checked with the HP Support Assistant and HP Instant Support Professional Edition (online tool from HP). I installed the drivers from the Intel Rapid Storage Technology technology and HP 3D keep.

  I also have a boot mSata SSD (120 GB mS200 Kingston). The 750 GB drive only for data (no OS on this subject).

  Any ideas, suggestions?

  Thanks in advance

  Update: today an HP technician installed a new MB, version of the BIOS F.11.

  Since that time (about 4 hours ago) no amount of control incorrect CMOS and BIOS don't reset errors,

  System seems to not operate normally if have I messed up anything?

  Hello

  This message always appears during the clean boot procedure or it appeared only once?

  Generally 'bad checksum' error message if the CMOS battery does not work correctly.

  But I have no idea why you get this message after update BIOS... Anyway if the laptop works correctly after updating the BIOS then you should t be worried.

• BIOS rom checksum error

  I have a bios rom checksum error on my hp pavilion a6530f. I replaced the battery on the motherboard and reset the CMOS but it still shows the black screen of death with the messages.

  I do not have a system disk and when I try to press F10 or F1 to access the window with the version of the bios information, according to the instructions I found on the HP site, nothing happens. I can't also find a download for any bios drivers for my pc on the Web site.

  Before this past that I have had some freezing problems and a lot of questions of adware.

  I used to operate and maintain fuji printing and developing of films but I'm kinda a tyro when it comes to PCs.

  Is that mean that the motherboard is fried? Or if not, where can I get the download that I need to solve this problem?

  Hello again cienerose,

  If you type the F10 at startup and nothing is happening on your computer (you don't get in your BIOS) then the problem you describe seems to be a physical problem, and I think it would be better if you contact HP Support for service options.
  
  I want to thank you for display on the HP Forums. Have a great day!

• System cmos checksum bad - default configuration used.

  Original title;

  HP 9000 - boot errors

  that means the following errors and how to fix: 0271 - check date and time settings and 0251 - checksum cmos bad system - default configuration used.

  Hi Joseph,.

  Since when are you facing this problem?

  The CMOS Checksum Bad error that is displayed depends on the type of BIOS used. One of these error conditions indicate that failure of a test of Basic Input/Output System (BIOS).

  There are two main reasons why fails a test of the BIOS:

  · The battery on the motherboard has lost its ability to provide energy. Date and time system are also affected by a defective battery.

  · The BIOS has been updated "evil." This can happen if the power is lost by updating the BIOS, or update the BIOS with an update that was not downloaded from HP, or when a virus or malware modifies the BIOS data.

  To resolve this error, use one of the following sections provided by HP.

  Note: BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  If your PC always shows errors about the clock or CMOS when starting the PC, the CMOS battery on the motherboard probably needs to be replaced.

  Alternatively, you can contact HP for help.

• HP divided x 2: BIOS Checksum Error (502) HP Split x 2

  A couple of days, I turned on my laptop (product number: G6Q88UA-#ABA) to see a black screen with white text saying he had a (502) BIOS Checksum error and press ENTER to reset the values and continue with my system startup. Once, I have to update to the current time. As the days passed, I noticed that I was unable to turn on my laptop without plugging it into the wall, and disconnect it would cause my computer turn off and therefore lost all of my work (and time settings). My poking around led me to him or the other being the CMOS battery, or a corrupted BIOS. I believe that my BIOS is up to date, and my model does not appear to be a CMOS battery.  Can anyone help? Thanks in advance.

• HP Pavilion dv2700 laptop displays the message "system CMOS checksum failed" every time you start

  

  Hi @all,

  I have a HP Pavilion dv2700 - kh933ea laptop computer #abv (it is a HP Pavilion dv2799ee Special Edition Entertainment Notebook PC to be exact) that displays the message "system CMOS checksum failed. Press F1 to continue"every time you start the system. My OS is Windows 7 / 32 bit.

  Then I updated my BIOS to version 2.4e, 01-dec-08 Phoenix (the SMBIOS version remained the same before 2.4), but the issue is not resolved. I have attached a screenshot for processor and BIOS versions.

  Can someone guide me on how to solve this problem?

  Thank you very much in advance.

  I don't see the screenshot of your post attachments. Please repost them.

  This error message means that WHAT BIOS is damaged. You will need to have the BIOS flashed in a mobile shop, repair a BIOS or an HP Service Center. Do a search online with Google or Bing repair for a BIOS.  If you keep trying to update the BIOS there will come a time where everything you have a black screen.

• Desktop M8000 giving Bios Rom Checksum Error

  Hello

  My brother-in-law gave me their old tower to see if I could not going again for their children to use, the decent machine actually, he had 2 internal hard drives in it and he said it was more than ever and lock up often.

  The pc don't was not start (sitting at an empty screen) even if it had worked before, so the first thing I did was to remove the two hard drives and their hung outside for my main pc, he said, I wanted to see if they were healthy and if they had the virus on them, etc.

  Health check, past, defragmented both drives them (OMG they were horrible) and on the storage disk ran a virus scan and spyware scan (zero problems) spybot seek and destroy and completely updated avast updated etc.

  On the main C drive, I did Defrag, ran the spybot captured about 10 things mostly of cookies, nothing horrible, then ran avast, it is 17 things in temporary files, remove hit at the end of the scan, re ran the scans and it came out clean.

  Then the two drives are checked as work/healthy, defragmented, virus and spyware cleaning, put it back in the system and I still get the screen white, but maybe 1 out of 10 times I get

  Found the CDrom, boot from it...

  But no matter what I (F-keys, deletion etc.) I can't get the pc to answer or do anything.

  I also removed and then re-inserted the cmos battery thought he could do something to help her back running but no luck, I have a new battery to install to try it but thought to take a few minutes of waiting and re - install could lead to something.

  These values of 12 volts out worrying par.2 1 tension or limits?

  The unit announces it will sound in case of errors, I get no flow in the readings or beeps, I just wanted to confirm on this.

  Cuz at this point, I checked the ram, hd, battery changed, makes the integrated reset cmos jumper option, but I don't always get anywhere then I suppose that its cpu or motherboard at this stage.

  Hello FTLOSM, reads that you list are fairly normal. A difference of one or two points on the readings should not be a problem, especially if the power supply is connected and powered. The 12 volt rails are mainly used for engines on the disks, so a small difference in the actual 12 volts would be well within tolerances. If 3.3 volts reading falls below 3 volts, then I'd be concerned.

  I would tend to think that the motherboard is the culprit, since it is rare that a processor will fail under normal circumstances.

  It usually takes a voltage spike to get a processor.

• Tecra M5 does not record the date and time - battery RTC or CMOS checksum is inconsistent

  My Tecra M5 PTM50E reverend new does not record the date and time. I loaded RTC battery for 8 hours when electricity is on in the said user's manual. I don't know where is the problem. The BIOS settings are respect after power is on.

  When I change any value in the BIOS, the changes are saved properly but date & time system restored to their value 01/01/2000, 00:00 every time when I get out of turning off more of 2-3 min. Message "RTC battery is low or CMOS checksum is inconsistent.

  Press [F1] to set Date/time"does not appear when I power on the computer. Any suggestions?

  Hi guys

  Usually this problem appears only if the CMOS (real time clock) battery is empty or corrupted.
  The real time clock battery powers the internal clock in real time and calendar. It also maintains the system configuration. If the RTC battery is completely discharged, the system loses these data and the real-time clock. In this case, the message RTC battery is low or CMOS checksum is inconsistent appears.

  So I see only two possibilities:
  Either you will charge the battery for real-time clock, or you ask the technician for replacement.

  Generally, the battery must be completely charged after 8-9 hoers but try to connect the laptop to the power adapter for a long time.
  If it will not help solve the problem if you contact the ASP for the RTC battery replacement.

• HP model #A6000n Bios Checksum error after update Bios!

  I did update the Bios posted on the Hp website... After the reboot, all I get is this error, "BIOS Checksum Error", the black screen then looks for a boot diskette drive (this computer has not), then it looks for a boot on the CD drive disc.  Now, I talked to HP support and they say I have to order the recovery disks.  Someone can send me a bootable file that I could burn it to a CD for this model machine and get it operational?  I have an older machine here that would allow me to make a bootable CD, but I have no idea where to find some sort of update of the BIOS and or file bootable to Flash the BIOS.  I am so angry that HP wanted me to buy this CD recovery program has just returned in Windows Vista.  But, I don't know what to do because the update of the BIOS must have been corrupted when I flashed the motherboard ASUS.  This computer is my aunts and she failed to save restore disks and now I'm lost as to lift this thing up and running... Help, please!

  Thank you!

  As I said, if you have a floppy is easy, especially since the computer diskette is XP. OK, let's go.

  (1) place the disk in the drive

  (2) open my computer and right-click on the floppy drive

  (3) choose the format on the menu that appears

  (4) put a check mark in the box "create an MS-DOS startup disk".

  5) click on 'start '.

  When 6) filled the awdflash.exe on the diskette copy

  (7) right click on the file of BIOS from HP

  (8) to move the mouse cursor in 7 - zip and click "open archives".

  (9) double click on the folder icon in the new window

  (10) right click on the ROM file - in this case 513. ROM

  (11) choose "copy to" from the menu and browse it on the floppy

  (12) when it is completed, the disk should be ready to work

  (13) move the floppy drive cable and the Ribbon in the Vista computer.  He didn't need to be mounted, but make sure that it does not touch something metal (participation of books will be good) and connect the water and the power supply to the motherboard and the power of the Vista computer (of course, it is done with both computers turned off and unplugged)

  Now ready to go on the Vista computer. When you press the power button on the computer, there will be a splash of HP come screen upward.  From this screen, press her "enter the BIOS' or 'Boot to install' as shown.  I forgot to ask if this screen appears in the previous posts.  If this screen does not appear then it will be much more difficult.

  When in the BIOS, look for boot order and then set it can boot from the floppy first.  Save the selection to get out.

  (14) reboot - should end up with a cursor blinking in the upper right

  (15) type AWDFLASH 513 rom/py/sn/cc , and then press ENTER.

  (16) when and if he finished power down and remove the drive from the computer disk

  That should do it.  If this does not work or there are problems come back with an explanation of what was happening.

  Of course, to do this at your own risk.  I'm just trying to help.
