What was the first laptop to support two external monitors?

What was the first laptop to support two external monitors? Wouldn't that be any laptop (or schleppable) that offers an ISA (or PC-Card) slot? After all, already the very first IBM-PC was capable to ...

Why did trackballs disappear?

Dirt is another issue. In a mouse, the hole where the ball is exposed is pointed down and stuff naturally falls out. On a trackball it naturally falls in. Goop, especially skin oils, gets stuck to ...

What is this port?

That would be USB, Audio out, Microphone in, FireWire. And PCMCIA slot above the two connectors. And there is a connector for a docking station at the bottom.

Why would installing Windows 9x on a Sager NP8200 or Wedge 466/DX2 laptop brick the system?

My theory for the Sager NP8200 case after some Internet search is that those laptops were having their video cards or some other critical components killed by setup during PnP hardware detection. A ...

Using generic SMPS adaptor on old IBM Thinkpad makes strange symptoms

I think you have a fake or mislabelled adapter. These symptoms seem to me to be those of a cheap adapter that's browning out when it's trying to supply the current the laptop wants at the voltage it ...

Using generic SMPS adaptor on old IBM Thinkpad makes strange symptoms
