Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: 14IMH9 family
What that covers: Lenovo PC; machine type/model determines BIOS, dock, ports, drivers and warranty configuration.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Tier — premium 2-in-1 CONVERTIBLE (Windows 11): A premium Windows 11 convertible — 360° hinge into tablet/tent/stand modes, an OLED touchscreen, a rotating soundbar hinge and pen support. Tablet-mode and pen symptoms apply.
Convertible modes: Folding past the keyboard switches to tablet mode and disables the keyboard/trackpad by design. Auto-rotate toggles in the Action Center.
Pen & OLED: Supports an active pen (a garaged/included pen on many builds) — a pen issue is usually a flat battery or pairing. OLED can show temporary image retention that clears.
Power path: Internal or removable battery. Every capability that costs current — night vision, higher stream quality, longer recordings, frequent events — is paid for in runtime, so a change in behaviour after a settings change is usually a power consequence rather than a fault. Cold weather reduces usable capacity sharply.

Exact questions

Questions that only have an answer for the Lenovo Yoga 9i 2-in-1 Gen 9

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

My Lenovo Yoga 9i keyboard doesn't work when I fold it.+

That is intended — folding the screen back past laptop mode into tent, stand or tablet mode makes Windows disable the physical keyboard and trackpad so you do not trigger keys against a surface. Fold it back to normal laptop mode and they return. If the keyboard is dead in laptop mode too, restart, update drivers via Lenovo Vantage, and check whether a tablet-mode state is stuck. The rotating soundbar hinge, meanwhile, is normal design, not a loose part.

Structured depth, not empty permutations

Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.
