Hello, on this laptop, the wifi can be up and stop working. I noticed it never works without battery, except long time after I remove the DC jack, and it stop to works (Bluetooth too). It diseapper to window and still 2 exclamation points in the device list.
The wifi chip is hot when the laptop is on.
I made a bios update but the same.
That could be a thermal issue, I measured 2 caps shorted (0 Ohms) beside the chip (+3V_WLAN according the bordview), but not since (so I have doubt what I saw). After, I measured 50 Ohms when battery plugged and K Ohms unplugged. So that could be a thermal effect… or not ?
I tryed to press on the wifi chip, no change, not yet tested with hot air but I will do.
From your experience, what can be the issue pls ? A wifi chip dead or bad solder is a common issue ? Do you have replaced or reflow this king of chip successfully ?
It is possible to remove the wifi shield ?
