Introduction |
| If your laptop has a dead CMOS battery and the OEM no longer sells new CMOS batteries (and aftermarket ones are hard to find), it is possible to take the dead battery apart and replace the cell so your laptop holds the CMOS contents again. | | '''''Note: This procedure is only recommended for older notebooks. If a replacement with leads is available, it's better to buy a pre-assembled battery. This approach is somewhat error-prone.''''' | | | '''''Guide notes:''''' | | * The cell does not need to be 100% covered. However, every visible area of the cell must be protected. '''''Liquid electrical tape is used to do this since it can be removed if something goes wrong.''''' | | * Disassembly of your laptop is not covered. '''''Every laptop is different, so research the disassembly procedure specific to your laptop.''''' | | * '''''This guide ONLY applies to coin cell rebuilds. Do not use this guide for other style batteries.''''' | | * '''''When adding tape to the cell, do not create a direct short.''''' To avoid this, place the tabs slightly higher than the factory placement and cut the tape sorter then you need. |
