  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.

• 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.

  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.

• 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

• How to wipe & restore PH3100U-1EXB to factory default configured using Vista?

  The partition was accidentally deleted during Vista re - install on the laptop, now the partion of virtual cd is not readable. :( There is no critical data on this drive.

  > The partition was accidentally deleted during Vista re - install on the laptop, now the partion of virtual cd is not readable
  You mean that the Toshiba HDD partition is more readable?

  Well, as far as I know the Toshiba backup software is installed on the Toshiba HDD partition, not the disk HARD inside of your computer. This means that you can connect the drive to any computer and have instant access to the backup software.
  But it also means that if you have deleted the partition on the external HARD disk so you won't be able to run the backup software.

  Please also consult the user manual:

• 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.

  I understand that you can not install some updates with the error message "failure of configuration of the Windows updates...". ». I can imagine the disadvantages suffered by you and will certainly help you in the right direction to solve the problem.

• Default configuration of the windows features. Restoration of the changes. Do not turn off your computer... HEEELLLPP!

  After restart my Asus X55oE due to necessary updates, I got «default configure features windows.» Restoration of the changes. Do not turn off your computer. After reading several messages through other forums, I turned it and then turn again only to receive the same screen. Some of these forums say that it can take 2 hours or more because of so many updates made at the same time. I think I was trying to upgrade windows 8 for windows 8.1.

  I'm really worried about it just because I just got back this PC from ASUS and am needing to work. Can someone tell me if there are other options or make sure that it just take a while? I also read that you can actually go to the control panel > windows update > help to erase mistakes. Also, someone said that you can customize the number of updates at a time can be both. I certainly do not happen again. Help would be greatly appreciated. Thank you in advance!

• 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

  sepyh

  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...

• I don't have a navigation bar and firefox does not open in safe mode to return to the default configuration. Does not work reinstall. Any help please.

  I have no navigation bar since I closed it to have more space on the screen. It will not re - open. Firefox does not open in safe mode, but immediately opens in normal mode with the new configuration incorrect, so I can't reset to default configuration. I deleted Firefox and re-installed and it always opens with the same faulty configuration. Why doesn't Firefox give me the safe mode dialog box, why can I not re - open the navigation bar, and how I can do those two things, please? Firefox is currently unusable for me without a navigation bar with no access to the default settings in safe mode. I can't search the extensions that I use since I have no navigation bar to go to tools, modules, Extensions.

  This has happened

  I closed the navigation bar to make more space on the screen and I could not re - open.

  Pass Vista (requires a minimum of 2 GB of RAM) and install Windows 7 (just 1 GB of memory for the 32-bit version).  If you buy the "Full" version (not the upgrade version) from Windows 7, you can Dual Boot between XP and Windows 7 (not all XP software will be running in Windows 7 and dual-boot will allow you to continue to use any software that you place a high value on the).

  You must first check if your Windows XP-based computer supports Windows 7  Go the the computer manufacturing technical support web site and see if they list Windows 7 device drivers. No driver Windows 7 means that you can not (the most often install Windows 7, if this isn't the case find Vista drivers).
