Is there a program or something?
Yes with teamviewer you don't even have to install it and it's free to go over the internet and network just start on both pc s and enter the access data from the pc in the laptop, then you control the pc with the lappi and can also write there
Is it also possible with USB?
For something like that, I would use the VNC protocol
(Alternatively, the slightly better NoMachine. But it is a company and not a free protocol. And unfortunately it doesn't work for me)
On the PC a VNC server e.g. ThightVnc
A VNC client on the laptop
This then runs over the network e.g. Wireless Internet access
Rather not… But if you had at least a mouse… You can use the on-screen keyboard
If I had a mouse… Oh how nice it is when you are pulled by the mother XD
if i had the mouse then i wouldn't need a teamviewer in the sense that that's enough to watch yt
Life is a dog
You love it but after a while it's gone
If you have Windows 10 Pro: Remote desktop connection
However, you have to activate something in the settings for this to work poorly without a mouse and keyboard. Why not ask a friend if he can lend it to you briefly or order one for you?
Can you do that from an old xp?
