 +Fortunately no components or traces were damaged. If you were to use this as a Windows device it would be worth soldering a new battery terminal header back on, but since this is intended for DOS gaming, pressing F1 to bypass BIOS defaults (and lack of date/time) at first power-on is not a real issue.
 +
 +=== Keyboard ===
 +
 +The keyboard as supplied with the laptop has some problems - certain keys around a third from the right hand side don't register correctly, and there are occasional "ghost" key presses that appear when no key is being pressed at all. It probably has some internal damage to the matrix (possibly a fluid spill, or a crack or similar).
 +
 +Will need replacing.
