Wireless adapter doesn't work and halts startup

[Mikkacchi]

Hi, I was cleaning the insides of my laptop as it was accumulating dust inside, and not just in the fan, so I decided to disassemble some parts(i.e. built-in battery, speaker module, HDD, motherboard, etc.) After cleaning, I reassembled the parts as it was before, then opened it. At first, everything looked fine, until I discovered that the touch screen function isn't working, and wasn't showing on the device manager. I rebooted the device but to no avail. So I reopened the PC and check for hardware problems. Detached some devices and all. After then, the touchscreen function was fixed, but now the wireless adapter isn't working. I tried rebooting a bunch of times, again to no avail  tried reconnecting everything again, but nothing happened. I gave up and decided to hook it up to a LAN cable for the meantime. All was good until one time, the PC shut off due to low battery, and when I opened it, it was stuck, and wasn't able to boot again. I tried system recovery and refreshing, but it always ends up in an error, so I decided to reformat the device. After reformatting, the PC still won't continue to boot(it was stuck to the hp loading screen). I tried detaching the wireless adapter completely, and the computer continued to boot.

Hope you can help me fix the problem.

Welcome to HP support community.

Run Extensive system test to check for hardware failures.

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4. Click Extensive Test.

5. Click Run once, or Loop until error. While the test is running, the time remaining and test result for each component are shown on the screen.

Reply back with the test results for further assistance.

Hi again. I've tried your method and it seems like the PC doesn't read my wireless device.

Wireless Module Check: NOT INSTALLED

Please also note that I've just reattached the module after recieving your reply. Will hope for further suggestions

@Mikkacchi If the wireless module is no longer detected, its most likely an issue with the connector on the motherboard or the wireless module itself, that said, I suggest you talk to HP support and discuss your options,

follow the below steps to get started:

1) Click on this link - http://www.hp.com/contacthp/

2) Click on Sign-in or select the product using the below step:

3) Enter the serial of your device.

4) Select the country from the drop-down.

5) Click on "Show Options".

Fill the web-form, to populate a case number and phone number for yourself!

Also, if you are having trouble navigating through the above options, it's most likely because the device is out of warranty, if yes? please send me a private message with the region you are contacting us from,
