Lenovo IdeaPad Slim 5 family is running very slowly

An IdeaPad Slim 5 that has become slow is usually busy or throttled, not broken. Open Task Manager and sort by CPU, memory and disk: an antivirus scan, a Windows update, a sync client or a browser with dozens of tabs explain most slowness. Check the power mode and Fn+Q cooling mode, because Quiet mode and Battery saver hold the processor back. Heat makes the laptop slow itself, so clean the vents and use a hard surface. A drive nearly full slows Windows, so free some storage, and turn off programs that start with Windows in Task Manager's Startup apps. Install the BIOS and driver updates from Lenovo Vantage and Windows updates. If the slowness started suddenly and the disk usage sits at 100 percent, check the drive's health;

a failing SSD needs a backup and service. Windows also slows after large updates, while it indexes files and the antivirus scans, so a laptop that is slow only for the first hours after an update will recover without any action. If the slowness is limited to one program, reinstalling that program or checking its own cache settings is quicker than resetting Windows. Lenovo Vantage's hardware scan checks the drive and memory and gives a result you can quote to support. Antivirus scans, OneDrive syncing and Windows Search indexing each use the drive and the processor in turn, so a laptop that feels slow right after sign-in may be waiting for them to finish, and an hour of idle time often clears it.
