Forgive me - this is plug, not plug-talk, and I should say something marginally germane to the original question. Even if the question is not about Linux, it is about laptops that support Linux very well. The yellow power sockets on Thinkpads have a tendency to crack if the adapter plug is stressed sideways. The short, large diameter socket is less prone to this than the tiny diameter connectors on many other laptop types, but there is always a breaking point, and it always happens to the socket before the power cord pulls apart. That leads to poor compression and contact. Fortunately, the 20V power sockets are typically on a pluggable wire harness. Aftermarket replacements are ≈$5. Unfortunately, on many thinkpads, you must remove close to 100 screws to get at the socket to replace it. Fortunately, there are PDF hardware maintenance manuals (HMM) for most of the earlier thinkpads. If you are careful about organizing the parts and the screws when the machine is stripped to tiny little bits, you can reassemble it correctly. You will need some fine-tipped jewelers sized pliers and #0 and #00 philips screwdrivers for most of this, and you Will Void The Warranty. With a couple of well-anchored egg cartons (or a compartmented plastic box for you vegans) you can keep all the little metric screws separated, step by step. Make lots of notes - the manual does not indicate which sized screws fit which hole. I like to number the subassemblies with post-its. The adapters themselves are cheap, not too much new from Lenovo. I find them at Goodwill from time to time and add them to my hoard. If you follow me around, I may forget one and you can grab that (hence the hoard). There are also ≈$10 aftermarket AC adapters on eBay. I have a few. Someday I will take one apart to see if it has the smart control circuit. It may be frying my cheap aftermarket batteries, which may also lack smart control circuits.
