(Refer to " Opening the case ".) To replace the battery, follow these steps:
1. Locate the battery on the motherboard.
Refer to the motherboard illustration to locate the battery. Gently pull the battery free from
its socket, taking care to note the "+" and "–" orientation of the battery.
2. Pinch the two notches together until the battery partially pops out.
3. Install the new battery in the socket.
4. Reassemble the computer and turn it back on.
5. Run the Setup program and reset the system time and date.
Dispose of used batteries in a safe, environmentally responsible manner. The literature that
comes with the computer may include an insert about disposing of batteries. If not, check with
your local government for information on where to recycle or dispose of old batteries. If you
cannot find the information you need, contact Toshiba for assistance. See the
Product Support
appendix for ways to contact Toshiba.
Expansion memory
The DRAM controller supports a 72-bit memory data interface. It can also support 64-bit or
72-bit wide DIMM modules with or without ECC/ EC.
Location of the
RAM DIMM
sockets
Synchronous DRAM (SDRAM) is supported. Memory can be configured in 1 M x 64/72,
2 MB x 64/72, 4 MB x 64/72, 8 MB x 64/72 and 16 MB x 64/72 single-
density DIMM modules
and up to 32 MB x 64/72 double- density DIMM modules.
The 3100 Series supports SDRAM at 100 MHz.
The main memory interface provides two 168-pin DIMM sockets, DIMM 0 and DIMM 1. This
allows system memory from 8 MB to 512 MB of SDRAM.
The DIMM sockets support single- or double- sided unbuffered DIMM modules. The installed
DRAM type can be 8 MB, 16 MB, 32 MB, 64 MB, 128MB or 256 MB DIMMs.
The DRAM controller uses the JEDEC standard serial presence detect mechanism to detect
memory and array configuration. No jumper settings are required for the memory size or type;
memory is automatically detected by the system BIOS.
3100 Series series computers are shipped with SDRAM.
