The d5000 and s5100 both have a replacement guide and should be similar to a degree, if you end up proceeding with the replacement please document it and create a guide for future users.

Based on what you’ve described it could be a bad connection or damaged wire. try investigating the wire. Also ensure there is no fail safe that requires you to restart the brush when moving from upright to normal position. some vacuums have this.

You should be able to side load the apps on - follow this guide to get the App Store, and you should be good after. https://www.youtube.com/watch?v=u7GDeXv0...

So the SSD in here should be similar to that of early 2015, OWC drives are certainly compatible and are very easy to switch out, no extra work needed (follow the guide below). I personally have swapped mine for a Crucial 1TB M.2 NVMe drive, it works fine with an adapter (about $20) and I have had 0 issues and at about half the cost. Some on iFixit, don’t like the adapter method for various reasons, but with High Sierra and onward the majority of the issues (hibernation issue for example) are no longer present. What ever option you chose the guide will walk you through doing the swap. MacBook Air 13" Early 2017 SSD -NVMe Replacement

You will have to ask each spot, with out their permission you could easily be kicked out, and if you don’t listen you would normally be looking at trespassing charges. Think about it form a business perspective, they operate the cafe/restaurant in order for people to buy and consume their products. They are not running a Shared work space. You can ask but I doubt you will have luck at any restaurant, and you have to remember if you choose to go ahead and use their space before asking they don’t owe you any favours so they are unlikely to talk to you away from your client leading to the possibility of both of you being kicked out. If you are going forward with this idea I think you would have better luck at a shared space where you can rent a desk/office by the hour and when needed. It will keep your costs reasonable and professional, the other option is in home repairs. Go to their home and fix it there.

yeah you can just buy some fabric dye and dye your jeans again, be careful dye gets everywhere!

First check to make sure all the connection terminals are clean, if they are all making contact check to see if your motor is blown. A muttimeter read on the bottom of the head will ensure the connections are good.

A new screen costs about $30 ( https://www.ebay.com/b/LCD-Screens-for-Venue-7/180235/bn_72773241 ) and there are repair guides on youtube. If you brought it to a repair store I would expect the repair to be $50-60

Some connection is probably not connected, watch the battery replacement and double check all your connections. Joy-Conバッテリーの交換
