Hi, I recently picked up a Minolta camera from an op shop, and put new batteries in (definitely the correct ones, model...

You could try 3d modeling them on a free modelling software (Autodesk fusion is a good choice), and then ordering them from a 3D printing service (such as Craftcloud, or a local one for you), and printing them out of TPU, which is a rubber-like material.

You can get a usb jailbreaker that enters all possible combinations onto a phone for cheap off AliExpress, but you have to first plug the phone into a computer and change the amount of times an incorrect password can be put in to the max (9999)

There might be a loose connection, or just a singular pin that is used for these functions. Try opening the phone, and then unplugging and replugging everything.

I had this issue on an old laptop once, and I somehow managed to get past it by unplugging and replugging the hard drive, but it only worked once. This may work, otherwise you could try a recovery tool (I Forgot My Password, etc). Otherwise, you can try professional data recovery, but if you don’t need the data, then you can replace the hardrive or format it. Windows formatting: "Open Disk Management (type diskmgmt.msc in the Run dialog)." Right-click the drive and select "Format." Follow the prompts to reformat the drive If you need the data, it will be hard if not impossible to get past the password. You may be able to plug it into a different device, which may prompt the hard drive encryption to bypass the password using the previously cached information.

Try buying a new hinge and the unscrewing the back, and taking the old hinge off, the tightly screw everything back on.

Maybe your battery is permanently dead, from water damage or something else. You could try replacing the battery and cleaning the components.

That could be your fans or your Hard drive, if you don't have a solid state.

I currently am using the Logitech G502 Hero wired mouse (the is also a wireless one). It is very durable and ergonomic. It is currently AU$150, but look out for sales, because I got mine for only AU$70. Link: https://www.logitechg.com/en-au/products/gaming-mice/g502-hero-gaming-mouse.910-005472.html
