How to check compatibility
Verify your laptop model matches our compatibility list above. Check your current battery’s part number (usually printed on the battery) matches Sony-VGP-BPS40-48Wh. For certainty, cross-reference with your laptop’s original documentation or contact the manufacturer’s authorised service centre.
When to replace
