    Hi this comment is correct. This guide completely skips the important step of removing and replacing the wifi cables. Without this step the computer is unable to retain its wifi functions

    How to replace the lcd?

    I have to agree with Sam Torres on this. I reached the same spot where the screen was off, but then which wire goes to which connector. The picture is too fuzzy to be completely clear. It looks like the one further to the back (lcd screen) might be the white one and the one closer to the front of the laptop (touchpad) might be teh black one but the only way to tell is to assemble everything and then get the bad or good news.

    VERY important. The guide doesn't mention detaching the display cable or the two small cables I assume is for the display's power. Please revise because I could have broken something if I wasn't paying attention.

    I agree, what saved me is that I was watching someone’s video in YouTube, if not I wouldn’t have know what I broke haha

A few steps in this guide are in the wrong order. Could get confusing for and unexperienced technician. Steps 10 - 12 should be before step 6. Other than that this was a very good guide.

Good catch! This guide was made by combining a few other guides ( we call prerequisite guides) and they were combined in the wrong order. I went ahead and fixed it. Thanks for the feedback!

This guide skips a very important step, without which the laptop is unable to connect to wifi networks at any reasonable range. You must reconnect the two cables on the left side of the monitor to the wifi chip. These must be in the order of white toward the monitor, black away from the monitor. I have taken pictures I would be happy to share for this step. Please contact me so I can share these pictures to remedy this oversight

Still not added,! Also the removal of three tiny screws under the lip of the CD Bay is completely unnecessary and they are very very difficult to put back in.

Was able to complete with little issue thanks to this guide! I did, however, run into one problem: After the battery is unscrewed, it still has small tabs to lock it into place on either side. In the pictures, it comes right out with no issue but mine was caught pretty well where the circuit board extends down. It took a nerve-wracking amount of careful prying to finally get the battery tabs clear of the silicon. Still highly doable, and this was extremely helpful!
