Remove all power -> meter in resistance mode -> measure the resistance to ground of each inductor on the board. Each inductor is linked to a local switching power supply and the resistance check is for confirming if there is a shorted component on that power rail. Make a note of any low resistance inductor and post your measurements.Comment

In case im attaching BIOS backup -
I've had this laptop for 8-9 years, and about a week back, it started malfunctioning. When I press the power button, the power LED comes on for about 5secs and turns off. The fan also doesn't spin at all during this time. But, if I press the power button, and then manually spin the fan, the laptop boots up and the fan starts spinning on its own. Even if I do this, and the laptop boots up, it turns off (hard shutdown) after some time between 10secs and 1hour randomly. I've tried checking the fan voltage and it's at zero volts when I press the power button without spinning it, but when I spin the...

Hello,
I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.
My question is, can I update the Bios on this G733 motherboard to a G533 Bios.
The reason for wanting to do this is that the keyboard isn't working as it should, and I think this... -
Hi everyone 😀,
I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.
To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.
Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:- I already own the exact same model, but its plastic chassis is badly damaged.

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...
