My wireless button is orange instead of its normal blue light and clicking it doesn't change it to the blue light.

All that is showing in the Network Adapter of my Device Manager is my ethernet (Realtek RTL8102E/8103E Family PCI) and not my Wireless LAN which used to show.

The wireless adapter is also not found in the Control Panel --->Mobile PC--->Adjust Commonly Used Mobility Settings. HP Network Assistant also doesn't work, which I also uninstalled and reinstalled.

At the start up screen, I receive a notice that Wireless Module is not found.

Here's what I've done so far, but with no success:

1) Updated to the latest BIOS version

2) Made sure the Wireless LAN is enabled in the BIOS screen

3) Ensured that there weren't any errors in the Network Adapter in the Device Manager

4) Sleep mode disabled in Power Management in Device Manager

5) Downloaded wireless adapter driver updates

6) System Restore to a previously working condition.

7) Opened the back of the computer where the wireless module is and reseated it just in case it shifted out of place when the laptop dropped. I did this by unscrewing the wireless module and putting it back into position.

I did all of this and my wireless adapter is still not found. If it was showing up then at least I can enable it if it had become disabled, but this is not even the case. On the exterior, nothing is broken. So I'm clueless on what to do.

Please, please, please help.

If it's a mouse I hear the same sound as I'd hear if I were to unplug it. Then it will stop working. 2 seconds later if I stop touching it I'll hear the sound that happens when I connect it and it works again

I don't really wanna strip it down till I know more about it.

My ASUS Transformer Book Flip TP500LA won't turn on at all. I've tried pressing and holding the power button, tried pressing all the keys, and still nothing.

I've checked the power adapter and there seems to be nothing wrong with the adapter. I bought a brand new one and out of the box it doesn't seem to charge my laptop or help it turn on.

Is it possible it's a problem with the battery? Please help!!

The only sign of life is a blinking orange LED beneath the charging port.

I tested original charger with multimeter, so that is fine. Also I checked the USB-C PSU. When I plugin a volt/ampere meter to the USB-C charger I can see the PD communication from laptop to PSU is fine: it get's up to 20V and pulls 0.4A.

I also tried to detach battery and CMOS battery, press power button for 15-30 sec then only attach power supply. Unfortunately that didn't help.

Does one have an idea what that blinking orange charger LED means? Only thing I can find online is according battery things. But that LED also blinks if if detached the battery and only provide power supply.

Are there good points to test voltage on the motherboard? Does the battery voltage pins need to have ~11V if PSU is attached?

Update - 2024-03-10:

For my feelings it's pulling to much current: 420mA with not battery attached. Feels like there is somewhere a short.

I did different measurements, but don't know how to narrow it down from here. Can someone guide me on measurements?

Update - 2024-03-14

Seems like the thunderbolt controller (or some peripheral of that) causes an issue. I tested with my fingers which chip is getting really really hot and it's that JHL7340.

Can one say if it must be that chip causing issues if it's getting hot, or if that might be related to some of its peripheral? I'm wondering if it's really shorted, as PD exchange with USB-C PSU is still working (but maybe it's not that chip doing PD exchange?!)

Update - 2024-04-29

I did a lot of reading and repair video viewing (thanks Sorin) now and decided to order a replacement chip on aliexpress as well as a cheap hot air station on amazon. After some trials on an old broken PC motherboard, I replaced that BGA chip in a fearlessly mood with the new one, with the result of "no short anymore".

Unfortunately that doesn't seem to be the only thing... Measurements on the main power rail look like the second mosfet is also shorted (0 Ohms resistance). So first mosfet gets 20V input, on the output it's gone...

So now, as I have the tools, I ordered that one on aliexpress too and will try to replace it. Will keep you updated, just in case someone stumbles over that topic here.

My power adapter has started to make lots of switching noise and I also need to replace the cord.

The design is unfortunately curved and the seam is very thin. I’m struggling to work out how to open it up.

Any advice?
