What to do if my Dell NOT21281 Laptop battery is swollen?
- WWilliam MitchellAug 5, 2025
If you observe that your Dell Laptop's lithium-ion battery is swollen, immediately discontinue using the laptop. Discharge the battery by disconnecting the AC adapter and allowing the battery to drain completely. Then, contact Dell product support to explore options for replacing the swollen battery under your applicable warranty or service contract.
