  • Technology Connections recently posted a detailed video about dehumidifiers that’s worth watching. But a key takeaway is that on an AC, the hot side is outside (making the inside cool), while in a dehumidifier they are directly next to each other (condensing the moisture).

    Without looking into the specifics, my guess is that it’s not routing the cold air over the hot side to keep things inside the same temperature.






  • If this is one of the physically smaller models, usually indicated by only having a USB connector (vs a separate power brick), you can probably ignore all of the advice to take it apart to use a SATA connector. These smaller ones don’t have SATA, but rather a soldered USB connector.

    The advice of using ddrescue, R Studio, etc is better, but still probably not going to help you if the drive doesn’t show up at all. At this point, you’re hoping that the drive lost its MBR/GPT (basically the table of contents) and nothing more. This really isn’t too likely, although you may have some luck getting the data you care about.

    Take the advice of professional recovery very seriously. You need to consider how important the data is to you, because this might be your only chance to recover it. Also, IME it’s usually a couple thousand, but that really depends on the service.


  • Thinkpads are extremely well documented. For how to repair/replace parts, you need the HMM. Just Google for “Thinkpad t14 Gen 1 HMM” and you should find the official PDF on their site. That will tell you, step by step, how to replace the keyboard.

    As for the part itself, you can again check Lenovo’s site for all compatible parts (FRUs) and find the item number and details. While I wouldn’t recommend buying directly from them due to cost, this should give you the information needed to find it elsewhere. eBay has tons of Thinkpads being sold for parts, and many of these will be parted out. You should have no issues finding what you’re looking for.



  • You are helping - they clearly need the additional training, and you’re doing everything you can to supply that. Their job can’t be relying on you.

    They shouldn’t (and almost certainly don’t) have delegation authority.

    For corporate bingo, the keywords are upskill, cross-training, and bus factor.


  • Don’t show. Guide them to do it themselves. Never be the one to actually do it beyond the first time.

    If they still refuse to learn, make them take notes. Make them read to you their notes from last time. Make them tell you what each step is and means.

    Make asking you the hardest option for them to get what they want.
