• 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

  If anything, I would just restore my old BIOS, if possible.

  Please, someone help!

  Hello

  Have you tried to access the BIOS and tried to set it to default settings?
  Isn't it? Do this!

  By pressing the F2 key, you would be able to access the BIOS. Set the BIOS back to default settings and set up.
  Then start the laptop again and check if the same notification will appear on the screen.

• Checksum error message incorrect A250 aftetr Bios Update on Equium A100

  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.

  BIOS ROM checksum error

  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.

  Question: I had the charger, the charger adapter and motherboard recently replaced under warranty and now it starts up with a black screen that says "Checksum Error press F5 to load Cmos default value press F6 to contunue"

  What does that mean?

  I noticed that my computer is a bit slow when starting and when I try to use the programs or loading anything.

  Thanks for your time.

  It's a problem of BIOS/motherboard.

  My advice would be to refer to the HP. something else may affect your warranty.

• 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.

  Hello @MValdiv,

  Thank you for visiting the HP Forums! A place where you can find solutions for your problems, with the help of the community!

  I came across your post about the BIOS and wanted to help!

  I have not seen a BIOS update for the operating system Windows 10 of your product.  You can try to install the BIOS for Windows 8.1.  Also, try to review the following document and let me know how it goes: HP PCs - BIOS HP Application selected is corrupt or missing

  I'm having the same problem. Did a fresh install of windows 7. Now, I can't go on the internet via ethernet cable. I have an Inspiron 570 (end 2009)

  I downloaded the driver: R243167.exe & R290807.exe

  Help, please! Thank you

  Please remove the serial number of your post. It is a violation of the terms of the forum to use to display a serial number and never share it with someone else than to Dell employees.

  Have you installed the chipset driver as the first driver charged after installing Win 7? without the chipset drivers cannot install or may not work.

• 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

  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.

• Inspiron 570 Factory Reset Win 7 SP1 desktop PC

  My Inspiron 570 Deskto was slow. I decided to do a factory reset. I backed up all my important files first. Then my pc got worse. It wouldn't boot.   I ran the diagnostics (F12) and he said I had bad sectors. Then I tried to do a factory reset (F8) I followed all the steps, but nothing happened. Now, the only way to run commands in windows is through CMD.

  I need help please.

  Thank you.

  Hello

  Please let us know the exact error code that arises during the diagnosis.

  If the code was 0142 or 0146 or DST smart test failed, then the HD is faulty and should be replaced.

  If the sectors are corrupted, then factory reset and windows installation will help only to a certain extent.
