that depends on how indepth you want to go into cleaning this thing. you can just take some compressed air and blow out the vents on the outside. or you can use one of the disassembly guides on this site and do a deep cleaning. those guides can be found here Xbox 360 S Repair good luck and i hope this helps
please see attached links. one is replacement parts for the ripstick https://www.ereplacementparts.com/razor-ripstik-skateboard-parts-c-194165_194171_194200.html and this is a video of the wheel replacement. i hope this helps https://www.youtube.com/watch?v=UrWy-eliBes EDIT: the wheels probably fell back off because from the pictures on the replacement parts site has loctite blue on the bolt itself to keep it from backing out.
it can be replaced but its a pain. id recommend when you take them off grabbing the metal headband instead of the earmuff itself. i did that for close to 2 years before i replaced them with a set of Logitech's. they never broke on the plastic, but the fabric muff got gross lol you might be able to use some JB weld if it hasnt fully broken yet to reinforce it. maybe use some material to up and down the crack. like cut up paper clip or toothpick possibly to put in the JB weld. without pictures its hard to suggest a fix. good luck!
going from a regular HD to a SSD would help in most cases. if the laptop is that old though it probably hasnt been cleaned in a while either. i would say if youre going in you might as well put new thermal paste on the heatsink and clean all the dust out as well! doing that may help quite a bit.
no ”Comparing PTC fuses to one-time fuses Every fuse has an amperage rating and protects downstream circuit components from damaging overcurrents. Both one-time and PTC resettable fuses connect in series with the load and are not polarity sensitive. PTC fuses reset themselves, whereas one-time fuses open the circuit as a one-time positive disconnect and must be replaced before resuming operation. Both technologies require the removal of the overcurrent condition to resume normal operation. Due to this key characteristic, selection parameters differ — some of which are compared in Table 1.” https://www.eaton.com/content/dam/eaton/...-components/resources/brochure/eaton-resettable-ptc-white-paper.pdf
it sounds like the power button needs to be replaced. whether or not you can replace it will depend on how much gear you have to repair it and your experiance. from the pictures on the teardown everything looks small so youll need to know how to microsolder. also there is plenty of experience here if you do decide to try and do it your self. if youre not confident enough to do those repairs then a shop may be able to do this for you! good luck!
in the software there are ways to make that part completely black. if youve gone through those settings and verified that theyre not disabled then you might be one of the lucky few where it just doesnt work. it seems like youve tried most of the troubleshooting steps on your own. but if the next one does the same thing then you might have bigger problems. make sure when you get the new one to do a fresh install of the software and use a different USB that you tried with the first keyboard!
