Lenovo power supply failure - is original the only safe choice?
After random shutdowns, I confirmed the Lenovo power supply needs replacement. Many sellers claim compatibility, but is an original PSU the only safe option, and where to buy it?

Recently I started reworking a mechanical setup in my workshop that involves a sliding section needing controlled movement, and the manual mechanism I used before is no longer giving stable results. When the load shifts, the travel becomes uneven, and sometimes the section stalls halfway, which makes the whole system unreliable. Since the frame is still solid, I’m looking into switching to an electric option that can handle repeated cycles without requiring a full redesign, but I’m unsure which motion components are suitable for mechanical systems that depend on consistent positioning.
I sometimes read forums about mobile games and recently came across Holi Rummy. I became curious about how this game feels in real life, rather than in descriptions. They write about a bonus of 51 rupees and instant withdrawals, but I wonder how convenient it is in practice and whether there are any delays or difficulties. Has anyone tried playing regularly, rather than just once or twice? And how do you feel about such card apps in general — more as entertainment or as something serious and an opportunity to earn money?
When I checked https://progressiveautomations.com.au/pages/mechanical-systems designed for modern Mechanical Systems Actuators setups, it became clear how linear actuators and lifting columns provide controlled movement, stable positioning and durability for different mechanical assemblies. Seeing how these components integrate into platforms or sliding sections made selecting a compatible actuator much easier.
