Mac Powerbook 190 Manualyellowplane
Any difference if you try starting without the main battery in place (you should not use a faulty/leaking battery anyway)?
There could be a number of reasons for a problem like this. A careful inspection of the board(s) (with a magnifying glass) may or may not reveal discoloured or cracked electronic components. Pay special attention to possibly leaking electrolytic capacitors.
The PowerBook 190 was Apple’s last model based on a Motorola 68040 CPU. The base model has a 640 x 480 4-bit passive matrix grayscale display; the 190cs has an 8-bit color display. Apple eliminated the internal modem bay and the ethernet port found in the PowerBook 500 series that preceded the 190, forcing buyers to acquire these items.

You may also want to use a multimeter to carry out a basic DC output voltage (approx. 24 V) test of the power adapter.

Description
Running a Motorola 68LC040 at 33Mhz, the PowerBook 190/190cs were identical apart from their screens. The PowerBook 190 had a 9.5” passive matrix greyscale screen and the PowerBook 190cs had a 10.4” passive matrix color display. The hard drive was 500Mb and there was a 1.44Mb floppy drive. The RAM was expandable to 36 or 40MB. An infra-red transceiver or video port for an external monitor were optional.
History
Targeted at a lower-end market like college students, the PowerBook 190/190cs didn’t have many of the frills found in the higher-end powerbooks. The passive matrix screen was less expensive but not as clear. Problems with the lithium-ion battery found in the PowerBook 5300 affected the Powerbook 190/190cs, even though they did not have the same issues of the battery exploding.
