Techy 2015

A test sheet used to record basic measurements on a 4 wire plus E & M circuit. For this project the functionality was mostly derived from either two pairs of copper wires or a 64K slot from a 2M PDH stream. The links connected train radio base station controllers with the central control for the railway route. See www.ipernity.com/doc/grahamh/24117033/in/group/873405

My wife's 3-4 years old Dell Inspiron 15R 5520 laptop failed. The power pack is shut down when it is plugged into the power socket, but otherwise works ok. I opened the laptop and found dried gunk and brown deposits and stains around a partly destroyed SMD. See note. I cleaned most the mess, as shown here, reassembled it but the fault remained. Tomorrow, Monday, I'll contact Dell Australia about parts, boards and new laptops. November 2015.

I opened the laptop and found dried gunk and brown deposits and stains around a partly destroyed SMD. This is the underside of the panel which supports the keypad. The circuit of the touchpad is the green circuit board. Tomorrow, Monday, I'll contact Dell Australia about parts, boards and new laptops. November 2015.
