Exam Season Laptop SOS – 5 Fixes Before Your Dissertation Is Due
Exam Season Laptop SOS – 5 Fixes Before Your Dissertation Is Due
Why Your Laptop Slows Down Right Before Exams
Every April, the same thing happens. Exam season hits, you open your laptop to start revising, and it takes three minutes to load a Word document. The spinning wheel becomes your new study partner.
We see a spike in laptop repairs at our City Rd shop every spring, and it’s not a coincidence. Here’s what’s going on and what you can do about it.
Your Laptop Has Been Working All Year Too
Think about what your laptop has been through since September. Nine months of lecture notes, downloaded PDFs, browser tabs left open overnight, software updates that installed half-finished, and apps you installed once for a group project and never removed.
All of that accumulates. Your hard drive fills up, your RAM gets eaten by background processes, and your startup time creeps from 30 seconds to two minutes without you noticing – until you actually need the machine to perform.
The 5 Most Common Reasons Student Laptops Slow Down
1. Storage Is Nearly Full
This is the biggest one. When your hard drive or SSD gets above 90% capacity, everything slows down dramatically. Your laptop needs free space to manage temporary files, virtual memory, and system updates.
Check your storage right now:
- Windows: Settings > System > Storage
- Mac: Apple menu > About This Mac > Storage
If you’re above 85%, that’s your problem. Old downloads, duplicate photos, cached Spotify songs, and lecture recordings from first year all add up.
2. Too Many Startup Programs
Every app you install tries to add itself to your startup list. Spotify, Discord, OneDrive, Teams, Zoom, Steam – they all want to launch when you turn your laptop on. Each one uses RAM and CPU before you’ve even opened Chrome.
On Windows, press Ctrl+Shift+Esc to open Task Manager, then click the Startup tab. Disable anything you don’t need running immediately.
3. You Still Have a Mechanical Hard Drive
If your laptop is more than three or four years old, it might still have a mechanical hard drive (HDD) instead of a solid-state drive (SSD). The difference is enormous – an SSD upgrade can make a five-year-old laptop feel new again.
An SSD reads data roughly 10 times faster than a mechanical drive. Boot time drops from two minutes to 15 seconds. Applications open instantly. This is the single best upgrade you can make to an older laptop.
4. Malware or Adware Running in the Background
Those free PDF converters and “study helper” browser extensions you downloaded? Some of them come bundled with adware that runs in the background, eating your CPU and RAM while serving you pop-up ads.
Signs of malware: random pop-ups, your browser homepage changing by itself, new toolbars appearing, or your fan running constantly even when you’re not doing much.
A professional virus and malware removal cleans all of this out and gets your laptop back to normal.
5. Thermal Throttling
Your laptop has a cooling fan. Over time, dust and fluff build up inside, blocking airflow. When the processor overheats, it deliberately slows itself down to prevent damage. This is called thermal throttling, and it’s extremely common in laptops that have never been cleaned internally.
If your laptop gets hot to the touch, the fan sounds like a jet engine, or it randomly shuts down – dust buildup is likely the cause.
Quick Fixes You Can Do Tonight
Before bringing your laptop in for repair, try these:
- Delete old files – empty your Downloads folder, clear your Recycle Bin/Trash, remove apps you don’t use
- Close browser tabs – 47 open Chrome tabs uses more RAM than most apps combined. Bookmark what you need and close the rest
- Restart your laptop – sounds obvious, but many students put their laptops to sleep instead of restarting. A proper restart clears temporary files and resets memory
- Run Windows Update – pending updates can cause background processes that slow everything down
- Check for malware – run Windows Defender (built-in) or download Malwarebytes for a free scan
When to Bring It to a Professional
If the quick fixes above don’t help, or if you’re dealing with hardware issues (overheating, battery dying fast, cracked screen, broken keyboard), it’s time for a professional repair.
Common pre-exam repairs we handle:
- SSD upgrades – the most impactful speed improvement, usually done same-day
- Screen replacements – cracked screens, dead pixels, flickering displays
- Battery replacements – if your laptop dies after 30 minutes unplugged, the battery needs replacing
- Virus removal – deep clean of malware, adware, and unwanted programs
- RAM upgrades – if your laptop has 4GB or 8GB and you’re running multiple applications, more RAM helps
- Thermal paste replacement and fan cleaning – fixes overheating and thermal throttling
Don’t Wait Until the Night Before Your Exam
The worst time to discover your laptop needs repair is the night before your dissertation is due. If your laptop has been showing signs of slowing down – sluggish startups, freezing, overheating, short battery life – get it sorted now while there’s time.
We’re at 1 City Rd, St Andrews, a two-minute walk from the town centre. Walk-ins welcome, and most repairs are completed within 24-48 hours.
