HP Error 601 Battery and Error 502 CMOS

[sgking]

HP dv7-3065dx Entertainment Notebook.  Win 7.

HP battery alert system detected battery capacity to be very low error 601 (internal battery).  So I changed the cell to a new CR 2032 battery.  Showed the same error. I changed to another new CR2032 battery.  The second time I did this I had a new 502 CMOS error along with the 601 error.  My clock reverted back to 2009, I lost some of the icons on the lower right, and my wireless internet disappeared.

Now I have two things that need to be fixed.

I turned on, immediately hti ESC, hit system diag. F2, Battery Test:

Battery Test Primary FAILED (on the first battery I put in, didn't check on the second)

Control - Device Mgr. - HP - Batteries - Microsoft AC Adapter, Microsoft ACPI Compliant Control Method Battery, and Microsoft Composit Battery all show that they work.

System CMOS/realtime clock says its working.

Microsoft System Mgmt. - BIOS Driver v. 6.1.7601.17514 from 6/21/2006 says it's the latest version.

I've manually updated my clock. I'll figure out the wireless and icons later I guess.  Just need to know what to do about the errors.

Hi

Error 601 is the battery that powers the computer, if you remove and leave only the power adapter connected, the errors disappear.

Primary (internal) battery 601

Terminator is correct.

"601" Internal battery error is misleading.

It is your main battery not the BIOS/RTC battery.

Thank you. So you mean that even though it says it's the internal battery its really the external battery?

I left my computer hooked up to the power supply last night and today all try icons and wifi are back where they are suppose to be.  I restarted and CMOS error is no longer coming up. Looks like all is well on that front.  Still getting battery error.

SG.

Power down the laptop.

Remove the main battery.

Power on the laptop and see if the error goes away.

Let us know what you find.

By Main battery, I assume you mean the cell battery CR2032. I removed it.

Now I have the CMOS 502 error again and the Battery 601 error.

SG.

Sorry should have made myself clear.

Power down laptop.

Turn laptop over and remove the MAIN battery.

The one you removed is the BIOS/RTC battery.

The "502" error just means that the BIOS lost power and reset to default settings.

Turn laptop upright and power on.

The "601" error should be gone.

Let us know.

Battery error gone.  Guess that means I need to replace the external (Main) battery.

I thought internal error referred to the cell battery.

Thanks.

SG.

Your correct you need to replace the MAIN battery.

Like I have said many other times.

That error is so misleading HP should have never used INTERNAL.

Replace the MAIN battery and you will be good to go.
