As mentioned by tech support there is no dedicated app for the Insp 7559 for windows 10. However, it is available for few other models mentioned in the link below
You're 100% sure? I searching for this app and found, under THIS installer, and now everything work's fine but, there's one more problem. When i set that i want to use mainly ac charger battery is anyway charing to 100% even if i set this in BIOS not in app.
You can try updating the BIOS, if you haven't already. Also try draining the Battery, then try using the ac only mode in the BIOS. Hope this link will be of help

@Lexlite & @ doti : I do not recommend you to try the BIOS update if your system not under warranty. It would be unfortunate if the BIOS update fails due to a power failure and end up in a 'no-boot scenario' there would no warranty service for this case.
