IdeaPad 5 15ALC05 defective hinge and broken mounting bracket in lid
A repairer describes an IdeaPad 5 15ALC05 brought to them with a defective hinge and a broken mounting bracket inside the lid. They note that reading Reddit threads suggests this is a larger weak point ('eine größere Schwachstelle') in these units.
What to check. The hinge/mounting bracket failure is a known weak point on this model line. Owners should handle the lid gently and watch for unusual resistance or creaking, as the repair requires replacing both the display lid and both hinges.
IdeaPad 5i 2-in-1 hinge screw backs out, shatters display glass
Owner reports hinge screw backing out during normal use, causing the display glass to shatter when closing the lid. Owner describes it as 'a widely documented structural issue across this specific model line.' Failure occurred just outside warranty, so the owner had to request a courtesy repair.
What to check. Check hinge integrity regularly; if a screw feels loose or the lid resistance changes, stop using the lid and have it serviced before the glass breaks. This failure can occur outside warranty, leaving the owner with a full display replacement cost.
IdeaPad 5i completely dead after being left unplugged overnight
Owner reports the laptop became completely unresponsive after being left unplugged overnight, 5 months after purchase. The machine would not power on, would not recognize the charger, and reset attempts failed.
What to check. A battery/power failure can occur within the first year. If the laptop dies after being unplugged, try the hard reset and charging steps, but be prepared that the battery or power board may need replacement — ideally under warranty.
IdeaPad 5i Pro 16 screen freezes during light work
Owner of a new IdeaPad 5i Pro 16 reports the screen froze during light work; the system remained responsive underneath (mouse moved, keyboard lights responded), and closing/reopening the lid recovered it. This points to a display or graphics driver-level freeze rather than a full system crash.
What to check. A frozen screen with responsive system underneath is often a driver or display pipeline issue. Try updating graphics drivers and Windows; if it recurs, it may be a hardware display fault worth checking under warranty.
