Whoa!
Switching power supplies have to be tested with a load on them: they
need the load to deliver proper voltages, and can be damaged if started

I read online that 1. Disconnect the 24 pin connector from the MB
2. Short out pins 15 (gnd) anbd 16(power on).
3. Test pins with voltages.
In any case with the power supply connected to the MB I was getting
nothing, not even a fan. The article I read was specific to the 24-pin
ATX 12V power
About 3 years ago I broke down and purchased an 'idiot light power
supply tester'. It was cheap and I have found several dead/dying
power supplies. Typically the -5 or -12 seems to go out first.
It could help many folks if Blu could purchase a box of them then use
them as door prises, holiday

you might try putting a 5 ohm 1A or larger resistor across the +5V to
provide some load. Sometimes switcher supplies seem to refuse to work
without some load to keep the occilator doing some work.
Or 12 ohm 1A or larger on the 12V.

Is this a trend? My ASUS VW266H also has a cold color temperature.

What did you use to perform the clone and how were the bad blocks reported?
After doing some web searches and a bit of reading on this, I get the
Also, should I use 'dd' to test all blocks before I put a drive into
service, or is there a better tool out there?
Besides the above tests, I've often used dd for reading and writing
the entire drive as an extra sanity test, and to force overwrites and
possibly reallocate any bad sectors:
Thanks a lot for your very informative response. I'll have to read
through the man-pages for hdparm and smartctl.
