IBM ThinkPad 340CSE

Hello, habrazhitel!

Today I will lead my story about - ,
come from the distant nineties.

Caution, a lot of pictures!

')
To my shame, I do not know the exact year of release of this model.

Features of this laptop:
Processor: IBM 486 SLC2 (66 Mhz!)
RAM: 4 MB (Expandable to 12 MB)
Hard Drive: 200 MB
Video chip from Cirrus logic
There is a built-in floppy drive
PCMCIA slot, LPT, COM, VGA, PS / 2 port for external mouse
Weight about 4 kg, you can fight back in the gate :)



Comparing the thickness of this laptop (Bottom) with an IBM ThinkPad 560X laptop (Top)



Rear view, from left to right: PS / 2, power, reset button, COM, PCMCIA, LPT, VGA

We start dismantling

Remove the cover (At the screen mount does not remain, it is kept only on the cables)


One cable is torn, so the screen does not work (Someone tried to restore by soldering.)


By the way, the screen controls the contrast and backlight


We do not need a screen, we remove it.

Keyboard as you should have noticed, German. In order to remove it, it is necessary to move it in the direction of loops until it clicks, and then lift it :)



And it connects in three loops



Remove the keyboard.
On the left is a floppy, on the right is a two hundred megabyte Toshiba hard drive, in the center there is a place for the battery.


Well, we shoot them too :)


Oops, the BIOS battery prevents you from removing the motherboard. We turn over the case, and climb into the battery compartment, which is hidden next to the battery



Remove them


Finally, remove the motherboard (along with the heat sink)


Turn off the heat sink.

Here we see the processor (The one on which something is glued gray) IBM 486, above it a video chip and 8 Toshiba main memory chips from the bottom and on the sides (Each chip 512 KB) - only 4 MB


Video chip Cirrus Logic CL-GD6245


Finally, the processor: IBM 486 SLC2 :)

Instead of conclusion

Plans to replace the cable and install instead of DOS 5.0 which now costs Windows 3.1.
The battery is almost dead, holds no more than 30 minutes.
The trackpoint is completely alive (I was shocked when I found out that using the trackpoint in BIOS you can move the mouse!)

PS I apologize for the terrible photos: (

UPD: Added photos of BIOS.
A duck, a thermometer, a screwdriver, a flag - these are all mouse cursors, which by the way are not static, but animated - a duck when it moves flapping its wings, the screwdriver rotates, the flag flutters ...
