I have a HP Pavilion dv6629us with Windows 7 32bit installed (it came with Vista originally). A few months ago I notice that the BIOS was outdated so I went to the HP website for the drivers of my laptop and downloaded the new BIOS. After that my computer haven't been charging and it doesn't detect the audio driver. If I go to Device Manager there's no Sound and Audio section and on Other Devices it shows 2 Base System Device and Compressor with a yellow triangle. I forced installed the Conexant driver for my computer on one of the Base System Devices but still the audio doesn't work. Also after the BIOS update my video card crashes every once in a while, the computer makes beeping noises sometimes and it takes A LONG TIME for the computer to shutdown or restart. It seems like somebody had the same issue on this topic but didn't post a solution.
