Troubleshooting

I hate this computer

We know. We’ve all been there, glaring at a spinning wheel while a deadline sails past. Before you hurl it into the canal, let’s see if it can be saved.

$ diagnose --laptop --mood=furious
> Scanning... found 83 browser tabs, 14 startup apps, 2 years without a restart.
> Recommendation: breathe.

Stage 1: free fixes (try these first)

  1. Actually restart it. Not close the lid. Restart. Sleep isn’t a reboot, and pending updates often slow everything down until you do.
  2. Count your tabs. Every browser tab uses memory. If you have more tabs than you have teeth, that’s the problem. Bookmark and close.
  3. Tame startup apps. On Windows, open Task Manager → Startup apps and disable anything you don’t need at boot. On a Mac, check System Settings → General → Login Items.
  4. Free up storage. A nearly full drive makes everything crawl. Aim to keep at least 15–20% free. Empty Downloads (you don’t need that 2019 printer driver).
  5. Run updates. Operating system, drivers and browser. Yes, even the one you’ve been postponing since spring.
  6. Check for nasties. Run your built-in security scan (Windows Security or your Mac’s built-in protections) and remove toolbars and “PC optimisers” you don’t remember installing.
  7. Plug it in and check power mode. Many laptops throttle hard on “battery saver”. Set Windows power mode to Balanced or Best performance when plugged in.
  8. Clean the vents. Dust makes laptops hot, and hot laptops slow themselves down. A gentle blast of compressed air (with the laptop off) can work wonders.

Stage 2: cheap fixes

  • Swap a hard drive for an SSD. If your laptop still has a spinning hard disk, this is the single best upgrade in computing. It can feel like a new machine.
  • Add RAM if your model has a free or replaceable slot. Going from 4GB to 8GB or 8GB to 16GB can transform multitasking. Check first: many modern laptops have soldered memory.
  • Replace a tired battery. If it only lasts 40 minutes, a new battery may be much cheaper than a new laptop.
  • Reset it. Back up everything, then do a clean reinstall or factory reset. It removes years of accumulated junk.

Stage 3: is it time to upgrade?

Replace it if…

  • It can’t run a supported, security-updated operating system (for example, Windows 10 support ended in October 2025, and many older PCs can’t officially run Windows 11).
  • It’s a Chromebook past its automatic update expiry date.
  • Repairs would cost more than about half the price of a decent replacement.
  • It has 4GB RAM soldered to the board and you use Windows.
  • You’ve done everything above and you still want to throw it.

Keep it if…

  • An SSD or RAM upgrade is possible and cheap.
  • It’s only slow in one app (that’s probably the app).
  • It still gets security updates and does what you need.
  • The problem is Wi-Fi. Test another device first – it might be your router.

Done with it? Recycle responsibly

Back up your files, sign out of your accounts, then wipe it with a factory reset. Many retailers offer trade-in or recycling schemes, and local council recycling centres accept electricals. Please don’t actually throw it in the canal.
