161 Real Time Clock Power Loss

 

If you have just replaced a motherboard and get this error:

 

1. Boot into this BIOS - Tap ESC or F10 repeatedly at power on.

2. File - Enter Time and Date.

3. F10 to Save and Exit.

4. Allow Windows to load.

5. Restart the computer and you should not have the error.

 

 

Side Note: If you're also seeing the 'Invalid Electronic Serial Number' error post motherboard replacement, see this forum post (with picturesSmiley Wink).

Re: 161 Real Time Clock Power Loss

Hi there @trdseal,

 

May the Forums be with you!  I understand that your computer is still getting a Real Time Clock Power loss message.  I am happy to give you a hand with this.

 

Please post the full product number for your computer. See the following, if you need help with that information.  HP Desktop PCs - How Do I Find My Model Number, Serial Number or Product Number?

 

Was the replacement battery new, and did you verify that it has a charge and there was nothing like a sticker or other insulating material on the battery to prevent an electrical contact?

 

Please let me know when you can.

Re: 161 Real Time Clock Power Loss

Thank you for the update, however when I search that model# you posted it is not pointing to one device but about 50. There may be a typo in the model you posted. Please double-check, or you can also give me any other product identifiers you can find on the computer.

 

Were you able to check that battery to make sure it is putting out the right voltage? Sometimes even a "new" battery may not be good, either due to storage time or conditions, or a defect.

Re: 161 Real Time Clock Power Loss

Thank you for the update. That came up as a HP Compaq 8200 Elite Ultra-slim PC Commercial model.

 

Did you check the contacts for the battery on the board, and verify it is putting out its rated voltage?  Assuming you have and the issue remains then, please use the following http://www.hp.com/contacthp, fill out the form, create a case for your issue and then use the provided information to contact HP.
