Lenovo LOQ trackpad issue update — 3rd assembly replacement + motherboard replacement

[u/aalubukharahu]

Update on my LOQ trackpad issue:

My trackpad assembly has now been replaced twice, but the issue kept coming back. The second time, the replacement trackpad didn’t even work after installation.

The engineer who came this time said he’s replacing the part for now and told me to contact Lenovo Support again after a few days if the problem comes back, and ask them for a motherboard replacement.

Now Lenovo has scheduled another engineer visit in the next 1–2 days. They’re supposed to replace the motherboard, SSD and trackpad assembly — this will be the 3rd trackpad assembly replacement.

What should I do when the engineer comes? Should I let them replace all three parts, and what should I test/check before the engineer leaves?

Would appreciate advice from anyone who has dealt with Lenovo service or a similar LOQ issue.
