A laptop is often the computer furthest from your hands: closed on a stand next to a monitor, plugged into the TV for a film, or open on the desk while you present from across the room. Controlling it from your phone fixes all three. The remote part is easy; what decides whether it works every time is a handful of laptop settings — lid, sleep, battery and Wi-Fi — that desktop PCs don't need.
Pick the kind of control first
- You need to see the laptop's screen on the phone (you're in another room, or away from home): remote desktop. Chrome Remote Desktop is free and works over the internet on Windows and Mac.
- You want a pointer and keyboard: a phone mouse app such as KDE Connect, Unified Remote or Remote Mouse. Our phone as a mouse and keyboard guide compares them.
- You're looking at the TV or monitor and want things to happen — play, pause, volume, open an app, next slide: a button deck and voice remote such as SofaDeck. One tap per job, no pointer to chase.
Laptop settings that make a phone remote reliable
1. Keep it awake with the lid closed (if you dock it)
Windows: open Control Panel → Hardware and Sound → Power Options → Choose what closing the lid does, and set "When I close the lid" to Do nothing under "Plugged in". Leave "On battery" as Sleep so it doesn't cook in a bag.
Mac: a MacBook stays awake with the lid closed only when it's connected to power and an external display. Without a display, keep the lid open.
2. Lengthen the sleep timer while plugged in
A remote can't wake a sleeping laptop over Wi-Fi in most cases. On Windows 11 go to Settings → System → Power & battery → Screen, sleep & hibernate timeouts and raise "When plugged in, put my device to sleep after". On a Mac, check System Settings → Battery → Options and turn on "Prevent automatic sleeping on power adapter when the display is off".
3. Stay on one private network
Laptops hop between networks. Phone remotes that work over Wi-Fi need the phone and laptop on the same network, and Windows only lets them in when that network is marked Private (Settings → Network & internet → Wi-Fi → your network → Network profile type). Guest networks and "client isolation" on some routers block devices from seeing each other.
4. Mind the battery
A laptop serving a remote all evening should be on its charger. Many laptops also have a battery-care limit (often in the maker's own app) that keeps a permanently plugged-in battery at around 80%, which is worth turning on for a laptop that lives on a stand.
Setting up SofaDeck on a laptop
- Install SofaDeck from the download page (or the Microsoft Store on Windows). It runs in the tray on Windows and the menu bar on a Mac.
- Scan the QR code it shows with your phone's camera and type the 6-digit PIN. The deck opens in the phone's browser — no app.
- Import your installed apps, then build a page for how you use the laptop: Docked (meeting mute, window layouts, lock), TV (play/pause, volume, YouTube, Netflix, full screen) or Presenting (next, previous, black screen).
- Add the deck to your phone's home screen so it opens like an app.
On a Mac, allow SofaDeck under System Settings → Privacy & Security → Accessibility so it can press keys and media keys; launching apps, volume and sleep work without it. The setup guide walks through pairing and building pages.

Frequently asked questions
Can I control my laptop from my phone with the lid closed?
Yes, if the laptop stays awake. On Windows, set 'When I close the lid' to 'Do nothing' (Control Panel → Hardware and Sound → Power Options → Choose what closing the lid does) for when it's plugged in. A MacBook only stays awake with the lid closed when it's on power and connected to an external display.
Why does my phone lose the connection to my laptop?
Usually the laptop went to sleep, or switched Wi-Fi networks. Plug it in, lengthen the sleep timer while it's on power, and make sure the laptop and phone are on the same network (not a guest network) and that Windows marks it as a Private network.
Can I control my laptop from my phone for free?
Yes. Chrome Remote Desktop is free for full-screen control, KDE Connect is free for mouse, keyboard and media control, and SofaDeck's free version gives you a page of 12 buttons plus the voice remote. SofaDeck Pro is $9.99 once if you want more pages and macros.
