Introduzione
A laptop's most vital component is its motherboard. If your Lenovo IdeaPad Flex 5-1570 starts to experience major issues such as not being able to turn on or starts to smoke/spark this is most likely due to a malfunctioning motherboard. Replacing the motherboard is a task that requires extreme care as it is attached to many other components that you need to remove in advance and if you're not careful you may also damage the computer further. It is critical that when you attempt to replace the motherboard the computer is turned off. Prior to assuming the problem is the motherboard, look at the troubleshooting page for this device to identify that the motherboard is the damaged component. This guide will teach you how to replace a motherboard in the event that it is malfunctioning.
Cosa ti serve
-

Remove the ten 5 mm Phillips #00 screws that are holding the back panel on.
-
-
-
Once all the clips have been disengaged, lift off the back cover.
You should probably disconnect the battery immediately after opening the laptop. Don’t want to risk damaging your nice hardware.

Using your fingers, grasp the entire bundle of wires to pull the battery cable from its connector. This will cut off power to the motherboard.

Remove the battery from the device.
My battery completely discharged and even plugging it in won’t power up my computer. I tried removing and replacing the battery, didn’t work, so I completely removed the battery and plugged it in, thinking that would isolate the battery as the issue, but still it will not power up, so I’m thinking it might not be the battery. Shouldn’t it work plugged in without a battery?
Any advice?

Using your hands, gently pull the hard drive back, sliding it out from the port.
There is an adhesive pad under the hard drive that had become "glued" to the hard drive, probably due to material breakdown. This made removing the drive quite difficult. I eventually was able to pry the drive loose, but not without some superficial damage to the hard drive case.

When is the soldering iron and solder needed? The tools list includes those items but nothing in the instructions calls for their use.
Has anyone tried a cross-generational motherboard upgrade? I have a dead i5-7200u motherboard and found an i5-8250u model on ebay for pretty cheap. The board layout, cutouts and ports look all the same to me.
I did it thanks to this guide, to move Motherboard to a better case, but
- I had to remove network card and it does not seem the guide mentions it
- I did not have to remove speakers
- I did not have to use soldering or even termal paste as I did not remove the heatsink. I treated it as part of the motherboard although it isn't.
- I did not have to remove RAM
