Thinkpad t60 motherboard pictures show problematic designs

This is today's news from a popular Chinese tech site

For those who cannot read chinese. Basically an owner of T60 discovered a yellow cable hanging on the bottom of the motherboard in place for a printed circuit. He reported this to the forum community and other people discovered the same thing happening on T60p and x60.

So they are raising questions and concerns regarding the quality of the motherboard made by Lenovo. I wonder if this is a common thing among notebooks? I own a t43 myself, of course I am not gonna bother open it up to check, but anyone with experience with motherboards of thinkpads confirm this?

all that means is a trace came from the board mfg that was wrong and they retrofitted the single wire. This happens all the time, especially on the first batches. But my experience is in automotive engine controllers and hybrid inverter control boards. I personally wouldn't worry about it. Those single lead wires are typically hand soldered by highly trained technicians. The Japanese supplier I used to work with (a household name company) swore by this technique.

 

Nothing to worry about, this is fine as long as it isn't going to dangle in aerospace under high G situations.
It happens very often in electronics industry, just a small fix to wrong PCB trace, usually indeed performed by highly trained technicians who do quality work on very fine soldering stuff. Even very expensive professional equipment may have few of such reworks when additional PCB manufacturing (and redesigning) cycle isn't an option due to being costly prohibitive.

 

Allow me to add another voice to affirm the replies already here. I've worked at a lot of companies that have developed PC boards and this happens a lot It is too expensive to rework a board for just one or two bad traces .. this is how it is done.
