What the symptoms may tell you
Memory pressure can make many open apps slow, but not every slow laptop is short of RAM. Some modern machines have soldered memory that cannot be replaced.
Safe checks to try first
- 1Check current RAM capacity and typical use in the operating system's built-in monitor.
- 2Find the exact model number, not just the brand or screen size.
- 3Save work and make a backup before any hardware change.
What to avoid
Do not buy memory based on a visual match; type, speed, slots and supported capacity must be checked.
Next step
Send the model and the tasks that slow down when several apps are open.
What I can help with
Supported RAM fitting is £49 labour plus RAM, or £20 labour during the same SSD job. Compatibility is confirmed first.
