WiFi menubar symbol shows hardware stays connected (even when issue occurs)
WiFi adapter shows normal connectivity symbol & stats: Using Opt+WiFi shows:
• Tx Rate: 867 Mbps
• RSSI: -44 dBm
• Noise: -90 dBm (same as working MBP connected to same router)
After ~1 min - 7 min, connectivity is lost (no traffic works) until I Disable / Enable WiFi (temporarily fixing again)
Inspected Antenna connections (look secure) & UP / DL is quick when working (same as good laptop)
• DL = ~400 Mbps
• UL = ~17 Mbps... -
Hi everyone,
I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.
🛠 Original Issue
The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.
I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

Hello,
I have a MacBook Pro M1 A2338 820-02020. It boots to OS but WiFi/Bluetooth are non-functional (exclamation point through WiFi symbol in menu bar) and the display is not working.
Starting at the WiFi chip... PP3V3_S2_WLBT_ISNS is fluctuating at around 2.4V. No shorts detected around UL000.
PPBUS_AON is 12V steady, but PPBUS_AON_3V3_S2_VIN_ISNS (measured at CC721) is 2.76V.
LC710 is getting 2.4V at P3V3_SW, which explains PP3V3_S2 fluctuating around 2.4V.
No detected shorts around UC710.
This makes me believe that RD560 has failed and... -
I received a 2013 Macbook Air A1466 820-3437-B motherboard with serial number C02L6GQ9FSV8 that came in WITHOUT a bios chip. I got a new bios chip and reprogrammed it. Macbook now powers on but doesn't boot the SSD. I've flashed a ton of bios but still same problem. Windows installation works with this Macbook but never a mac installation. Unfortunately, since I didn't receive this macbook with a bios chip, I don't have the original bios. What can I do now?... -
I just bought a new ThinkPad laptop and I need to connect it to my home network. I have several computers on my network and can see each other in File Explorer and the older ones can communicate with each other (even with the new one) but the ThinkPad can see the other computers but can't communicate with them. I get the (network error 0x80070035 The network path not found). I tried several scenarios that I found on line but none of them worked?? Since the other computers on the network can communicate fine I'm assuming the problem is with the setup of the ThinkPad? All computers are running Windows...
