I惴 glad to report success: after a few initial attempts, I finally managed to get the speck off - literally saw it flying away once I blew the air stream in the right direction. It was encroached and resisted a bit but now it愀 history :-)
The most important precaution was not to shake the compressed air can, which has the effect of adding some gas (propellent I imagine) added to the stream, with a noticeable coldness involved due to the sudden expansion (my thermodynamics days are long gone, so this could be just nonsense).
There愀 still a little imperfection in the display, which ironically appears to be the remainings of condensation rings - formed by the dirt existing there after it dried off. It appears that the previous owner had attempted to blow the dust mote off but failed. It愀 much less noticeable, definitely I惻l learn to ignore it as db suggested.
I was also cleaning the keyboard with isopropil alcohol (my usual method for the standard treatment) but I got concerned about the shift yellow lables: I think I noticed some light wear and stopped immediately. Does anybody know whether tallkeys units had different lables more susceptible to get wiped off?
BTW the unit has the screw posts *intact*, surely those nuts on the bottom ones must help - shame HP stopped using them, the precursor of "planned obsolescence" perhaps?
