Samsung NoteMaster 386s/25
One of early Samsung computers is compact, has floppy disk drive, hard disk and replaceable battery. It has VGA-compatible grayscale LCD allowing up to 640x480 resolution. Manufacturing quality is not good, at least in my unit, and the only thing which made this device survived is that it was not used much, stored for years in closed casing. Keyboard is soft,

Well, this thing just boots to DOS.
It has 3 batteries: Main one, CMOS and RAM battery. All of these may leak, so it's better to store them away from laptop. Main battery can be easily removed, as it's a module. CMOS battery can be substituted with CR2032 + diode, RAM battery is 6V, 120mAh. To access these two batteries keyboard must be removed by carefully prying it out. To remove RAM battery bottom screws must be removed - 2 bottom and one below keyboard, these closest to the user. Now bottom of cover may be gently pulled (NOT entirely, it's still mounted to bottom part!) and battery removed.
