HP Pavilion 15-cc561st I/O Board Replacement

Introdução

Use this guide to replace the input/output board in an HP Pavilion 15-cc561st laptop (product number 1KU29UA).

The I/O board is a PCBA with two USB 3.x SuperSpeed ports, an audio-out (headphone)/audio-in (microphone) combo jack, and a memory card reader.

The USB ports are used for connecting USB devices. The Audio-out/Audio-In combo jack is used for connecting powered stereo speakers, headphones, earbuds, a headset, or a television audio cable. It can also connects a headset microphone, but the jack does not support standalone microphones. The memory card reader is used to access and manage memory on SD cards.

Problems related to these ports may be software rather than hardware related, for example, outdated audio drivers.

Shut down the laptop, disconnect all external devices, and unplug the AC adapter before beginning. Take the appropriate precautions if your battery is swollen.

Before you begin to remove the bottom cover, shut down the computer. Disconnect all external devices and unplug the AC adapter. Flip the laptop upside down.
Use a Phillips #0 screwdriver to remove five screws from the bottom cover:
Two 5.6 mm screws
Each of these screws are beneath the two rubber feet on the rear side of the laptop (near the display hinges). You do not have to completely remove the rubber feet to remove the screws; simply peel the top of the feet to reveal the screws.
Three 5.8 mm screws
Throughout this repair, keep track of each screw size and location to avoid damaging your device.

Use the opening tool again on the left and right sides.
Start prying at the areas closer to the rear of the laptop (near the display hinges) before moving towards areas that are closer to the front of the laptop (away from the display hinges).
Pry a little bit on the left side, then pry a little bit on the right side before prying more on the left side again. Working on both sides in this incremental fashion is easier than completely prying one side before starting the other side.
