White spot on Lenovo laptop screen
On Lenovo ThinkPad and IdeaPad screens this is a known pattern: a bright, soft-edged white spot that shows on dark backgrounds, most often near the lower half of the screen.

Full-screen black. The spot will glow; on full-screen white it disappears. If it stays on white, it is something else — use the dead pixel test.
What it is
On Lenovo ThinkPad and IdeaPad screens this is a known pattern: a bright, soft-edged white spot that shows on dark backgrounds, most often near the lower half of the screen. The cause is a reflector dot inside the backlight coming loose from its adhesive — heat from the CPU under that part of the lid and pressure on the closed lid both bring it on. It is not a dead pixel and the panel itself is usually fine.
Can it be fixed?
Yes, by a repair shop re-gluing the reflector — a small job. Lenovo treats it as a display fault under warranty; out of warranty, a shop repair is far cheaper than a panel. Software does nothing for it.
What to do
- Confirm on the black test that it vanishes on white.
- Under warranty: raise a display fault with Lenovo support with a photo on a black screen.
- Out of warranty: ask a repair shop for backlight reflector repair; expect it to take a day.
- Until then, keep the laptop out of tight bags — pressure on the lid makes more dots.
What a repair costs

Warranty
Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).
