Windows 7: The Power Button

02 Dec 2012   #1

Windows 7 Ultimate 32-bit (6.1, Build 7601)
The Power Button

Usually when I put my computer into sleep mode the power button goes orange but now when I turn my computer into sleep mode the color is blue and its flickering at first I didn't notice because I left the PC but when I came back its flickering on and off I thought an error happened but when I pressed it, it woke up normally. Is their anyway to fix this? Because its annoying, I think it has nothing to do with any software or programs. I didn't touch any hardware parts except for the RAM that I cleaned.

You touched the RAM? How did you clean it? A flashing blue light may be an indication of a hardware issue.

I would power off the computer completely, unplug it, then press and hold the power button for at least 30 seconds. Next, open it up and remove the RAM, then install it again. Be sure it is installed evenly and securely. Re-assemble the casing, plug it in, and see if the flashing blue light is gone. If it does not, then try running diagnostics. HP provides them on their website for download.

WARNING: Because of the cold weather, be sure to use a grounding strap before touching the RAM. If you don't have one, then at least try to be sure you're electrically discharged by touching a metal object.

Normally a blue flashing light means the PC is in S1 sleep state.
In S3 sleep mode, the light is usually off.
I've never had an orange light when sleeping, so I'm not sure what that indicates.
I couldn't find a manual for the Pavilion P6640D on the HP support site.

When you cleaned RAM, it may have made some BIOS settings changes.
I would go into BIOS setup and check the sleep setting.

If it's set to S1, see if you can change it to S3.

Do you have a desktop or laptop?
Maybe the orange light indicates hibernate...???

@cytherian: I did what you posted (Remove RAM and put back in) and still the same.
@DavidW7ncus: "When you cleaned RAM, it may have made some BIOS settings changes." I think yeah because before this happened my boot up shows the HP logo with a blue background. Now it shows a screen similar to a picture below and I'm sure its on sleep mode and its a desktop.

Hello Patrick,

Double check through your power management BIOS settings. There's most likely one that has an option to turn off or change your case power button light. Afterwards, save your BIOS settings to apply.

Hope this may help,

@Brink: On power Management there's no option to change the light of the power button.
