Re: Lenovo T570 no SSD detected

BTW, this model also allows you install a M2 2242 SSD into the WWAN slot. I did this initially, but my daughter complained the lappie was sluggish after that. Once I fixed the original 2.5" adaptor...

Re: Recover data from Lenovo Thinkpad X1 Carbon 6th Generation w/ USB Logic Analyzer

Re: Macbook a1398 2015 Wont go into recovery

The MAC should boot off a USB MAC OS installer regardless of key combo, unless it has a firmware password. For example, if you have the flashing folder icon, it should revert to the Apple logo and...

Re: lenovo 300e 2nd gen dead

USB-C doesn't work like that. Channel configuration pins on either side (CC1/CC2) detect when it's plugged in and power is only thereafter. Get a USB-C ammeter to establish what is happening with the...

Re: how to test power button when it is on keyboard

Power buttons on keyboards can be metered usually at the last two pins of the keyboard connector, at least this is what I've found so far. One of the two will be ground of course, determine that with...

Re: Alienware 15 R3 Motherboard Issues Help Plz!

Replace the battery first. Some charger designs utilise power from the battery when the system power requirements exceed that of the adaptor. Given your adaptor shuts off, that is the likely scenario.

Re: Macbook pro 15" 2018. keyboard backlight not working

You can run a MAC in clamshell mode if the screen is U/S, no need to remove it. Allows you to at least set it up on external monitor, you just need an external USB-C hub that supports HDMI, power...

Re: Macbook pro 15" 2018. keyboard backlight not working

The previous models use an ambient light sensor in the screen to turn it on/off. Wastes battery if it's daylight, so it's switched off in that case. So with that missing, I'd say that's your issue.

Re: 820-00165 no power, 08-80ma, PM_SLP_S4_L is pulsing.

Check for corrosion on the JTAG connector (J6100), that's a more likely cause. Also check termination resistors for corrosion etc around U6100 and the connecting resistors to the CPU (around middle...

Re: Mack book pro A1707 lcd problem

Apple have (or had) a service program for it, however its confined to 2016 models only. Since they were only manufactured from October 2016, it only covers about 3 months worth. It's the same issue,...

SVOD3 debug ZIF programming PCB

Re: Asus X550CC (F550D) component identification

Thank you, this boardview is different to the one I had and does show the values.

This section is under a plastic sheet so I'm thinking it's more likely to be a dead bug decomposing etc.

Asus X550CC (F550D) component identification

Have a X550CC motherboard with some slight liquid damage. There are 3 corroded resistors; PR8512, PR8513 and PR8516. The first one (PR8512) is missing off the board, but very well have fallen off. I...

Re: Acer Spin 5 - Turns on and off after a few seconds

A lot of weird power issues on Acers are usually keyboard related, as power button is integrated. Original fault fits what I’ve seen. Disconnect keyboard and power on by shorting the 2 end pins of...

Re: Macbook Air A1465 - 820-00164-A , No reaction to power button

PPBUS_G3H will be around 8.3V with no SMC comms to the ISL, otherwise should be 8.6V. When the board is out of the chassis and no battery connected, the board should start up when power is applied....

Re: iMac 27 Late 2013 - Fan noise , OS very slow

From memory, that error code means some sensor data is missing (hence the throttling and high fan speed). I think Apple Hardware test only supports iMacs up to early 2013 unfortunately. You'll need...

Re: MacBook Air 1466 820-00165 I/O board schematics

There aren't any schematics for the boards used in 2013~2017 Air's. The one wire circuit is identical though to previous MAC's (where these components were on the main board) so isn't too hard to...

Re: Macbook Air A1465 - 820-00164-A , No reaction to power button

PPBUS_G3H should be measured with battery disconnected. Check for corrosion or evidence of liquid ingress (especially around the SMC). Usually if you get a single pulse of voltages up to Vcore it's...

Re: Macbook Air A1466 820-000165 Fan allways on 6200rpm

Confirm prescence of fan tach using a scope to the SMC. If it’s missing, fan will be driven at full speed.

Re: Macbook Pro early 2011 - no audio

Board number would help. Track/via damage is the most likely suspect around that area. Via's can be underneath the resistor track pad itself or the test point. If one end of that resistor is going...

Re: Macbook Air A1466 2013 reboot and kernel panic

That's corrosion. Check all pads/via's in that area for continuity to other nets using the boardview.
