About this CMOS battery
A CMOS battery is a small coin cell that keeps the clock and firmware settings when power is removed. It matters when the computer is unplugged or the main battery is flat. Laptop versions are often sleeved with a short lead and connector; other boards take a bare cell in a holder. Match cell type, lead and plug before fitting. When weak, the date falls back to a default and settings vanish. Start-up can halt with a clock or checksum warning until a key is pressed.
Is this the right part?
Find the cell type on its face; on sleeved laptop cells, read the part number on the wrap. Before fitting, compare the type, any lead and connector, and whether yours clips into a board holder. The manufacturer's part number for this listing is 01HY790.
Not sure? Send us the number from the label, or your machine's serial number, and we will confirm the match before you order.
