Solved How can I disable the SD card reader in my Pavillion 20

January 14, 2015 at 19:19:13
Specs: Windows 7
The computer does not boot up. I opened the back to disconnect the card reader but it is soldered in and I don't have the tools. With the computer off I shorted all card reader pins reconnected the power turned on and away it went. However when I turned it off and turned it back on I have the same problem. I'm wondering if I can disable (somehow) the SD Card reader What if I disable the drivers

Thanks all repaired under warranty. they replaced the mother board. Appreciate the advice. Have not selected a best answer as it was done under warranty however resetting the bios battery was on the right track.
Cheers Gary

Desktop or laptop?
Why did you suspect the problem was tied to the card reader?
What other problems have you been having recently?
If this is a desktop, the card reader and front USB ports are part of a hub built into the case front and there will be a wire/plug that goes to the motherboard USB internal jack. Unplugging this connector would confirm if the hub or its parts were involved in the problem without doing irreversible damage to that part of the case. Make sure that the system is unplugged and you ground yourself from static discharge potential before reaching into the case.

You have to be a little bit crazy to keep you from going insane.

It is a HP Pavillion 20 all in one touch screen. When I start the computer the SD card reader LED flashes.
When I got it to work last time it read from the hard drive.
I shut down properly but now have same problem again.
I found on a blog that the card reader seems to hijack the start up or something

Also try discharging the motherboard:
Turn off and remove power.
Remove battery.
Hold Power Off/on button in for about 30 seconds.

Always pop back and let us know the outcome - thanks

Check your boot order and remove USB drives from the boot order.

Ref. #4:
Boot order is in BIOS set up. See online manual to find out how to access BIOS set up (if you do not already know), it is usually a key to tap during boot up, on HP I think it might be the Delete key, but check.

Thanks all for the help
After a lot of research it seems this is a regular problem with HP
I did remove bios batteries etc and it worked but next time on boot up it did the same thing again.
Interestingly on line the HP said it was out of warranty but when I checked my customer receipt it was not out of the shop warranty so I have taken it back to them. Interestingly the person booking in the computer said they have a lot being returned with the same fault. Research on the net indicated that this fault has been around for a while.
So now it's in the hands of HP ( or designated repair centre) to repair.
Will keep updated on result.
Many thanks

It's good to hear that they accepted it under warranty and thanks for letting us know. I never quite understood why you suspected the card reader in the first place. If you manage to find out the cause it would be great to hear from you.

I suspected the card reader as the LED indicating the computer was trying to access the card reader was flashing. As soon as Power was applied it would immediately start to try to access the card reader. In my younger days I used dig that rock n roll but seriously I used to play and teach assembly programming so have a sort of idea of whats happening. Unfortunately now technology has improved that slightly older users like me with a semblance of knowledge can identify the area but don't know where to go from there. I did remove the Bios battery and let the whole system "empty" it's voltage tanks and that worked but as soon as I shut down "properly" the problem came back. I did try to reset the Bios to load from Windows But as I said it started to get complicated.
Thanks for interest and will advise the outcome
