Failing RTC accuracy test

Question

Hello everyone,

I have a problem with a 2 week old XPS 17 L702x laptop. The computer clock is erratic, loses time, and is always wrong, so I keep having to update it by synchronising with internet time. When I run the DELL PC Checkup motherboard tests, the RTC rollover test passes but the RTC accuracy test fails (I presume "RTC" means "Real Time Clock"). I get an error code of "WSB01-H80". Anyone have any ideas before I phone Dell? Could it be the coin battery?

Thanks in anticipation of your help,

LesterL

No, it's not the battery -- call;  they will have to replace the system board under warranty.

I have already replaced the motherboard and my warranty has expired... what can I do to fix this problem, is there any software i can instal to fix it. My computer takes a long time to start up and it shuts completely down even when i put it to sleep.

Hi vmme2020, Are you getting an error 'Failing RTC accuracy test'? If yes, may I know when do you get this error message? Please share the system model and Operating system. To check the system hardware functionality, you can run a hardware diagnostic test by following the steps below: Please restart the system. As soon as you see the blue Dell logo, start tapping the ‘F12’ key on top of the keyboard. Note: If you wait too long and the Microsoft Windows appears, then continue to wait until you see the Windows desktop. Now shutdown your computer and try again. After you tap ‘F12’ key, a new window would appear in front of you. Use the 'Down' arrow key to highlight the option 'Diagnostics' Hit Enter to initiate diagnostics and make a note of error code if any.  Please reply with information.
