La batería de mi dispositivo se agota en un día sin usarlo, ya lo reinicie y conecte su cargador y se sigue acabando la pila, no me dura el mismo tiempo como siempre estoy acostumbrado a usarlo

When I turn the power on to my WF-3640 it starts beeping and flashing with message close cover then back to standby over and over never ending. I can shake it and it will work for a while then starts over. How do I access the sensor and clean it?

long story short, I live in Argentina, I got myself a Ps5 from Japan (CFI-1200A), voltage input is 100V ~ 3.55A 50/60MHz, electricity here runs at 220v 50Hz.... can I plug it to the wall? Seller says yes, internet says mixed responses, what should I do?

EDIT:

So, after comunicating with Sony Japan (which was a tedious task due to having to use google translator since no english speaking employee was present at the time), they told me that CFI-1200A model has a psu rated for 100v, so overseas usage wasn't possible, and they didn't adviced using a transformer (i assume it's as a disclaimer in case something gets damaged)... Sooo, I took the risk and used one (750W), and was able to play for like 3 hours, wires, transformer and PS5 were pretty cool, so I think everything is looking good.

I'm yet to open the console and check if the psu is dual voltage or not, but taking in consideration what the japanese dude told me, it seems it is not.

Error 3000 - Neato does not start moving

My Neato Botvac 80 has been working well. Today I changed its battery. It was working well until now. It gets ready to start but then stops and give me the message “press OK to continue (3000)”. I press OK and it tries to get ready but again stops and sends the same message.

What did I do? I cleaned its laser area with a cotton tip and pressured air too. Nothing. The disk moves though.

Any suggestions on what could happen but mainly how to fix it?

Thanks!
