Default No Startup Laptop

So let's say the laptop will power on, show the power on light and tick
tick the CD but nothing shows on the screen and the HDD light does not
flash.

If I then put in a CD and then power off and hard boot but it will not
load anything from the CD?

CDs tried contained:
Linux Mint
Macrium Reflect Free 6
Recovery Disk specifically for this laptop.

Will bad HDD hold it up?
Will CMOS hold it up?

This laptop did boot all the way to Win 7 (Win 7 looked good) once
after many retries but will not boot again.

Next step suggestions please.

The next step is definitely to get to your nearest Geek Guys shop and
ask him if he could change the Motherboard for you cheaply. If not then
you will need to buy a new machine.

The signs are that the machine is kaput. If it can't start by pressing
the power button once and normally without using any force then the
machine is dead.

I have noticed that you have been having problems for the past 3 to 4
weeks and you haven't made any progress yet. Do you not think that it
is time to take some rest and think of buying a new machine? Me think so.

What brand and model of computer is this? Without knowing that, I would
remove the RAM and clean the contacts, then install it and try it again.
Also is the CMOS battery good? Some computers have a problem if it is
not. If you have another power supply, I would try it. A weak PS with
low current also produces some strange problems.

Start with the easy fixes before looking for the complex.

My guess is, by getting the unit to boot once, whatever
was on there (malware wise), has finished the job it started.

I would pull the hard drive and do an offline scan
of the contents while using another computer. This
tool, for example. This makes bootable media, which
you use to boot your technician computer, and do an
offline scan of the cabled-up laptop drive. It can scan
the hard drive MBR, as well as the partitions.

That's nitpicking, if it supplies power then it's a power supply!

There are some minor distinctions.

The ATX Power supply makes voltage intended for
immediate consumption. The +12V from the ATX Power
supply operated the 3.5" hard drive motor. The +5V operates
some of the logic ICs on the hard drive controller board.
The ATX supply makes +12V, +5V, +3.3V, -5V (deprecated), -12V, +5VSB.

At one time, it might have been possible to build a
motherboard, with almost no secondary regulation at
all on it. As at one time, processors ran at relatively
high voltages. And that set of six voltages could power
the motherboard directly.

A certain amount of that has changed over the years. Logic
IC core voltages have dropped considerably. The core operates
on a power-saving low voltage, while the I/O pins operate
on the selected I/O voltage (maybe 3.3V for general purpose
CMOS-type signals). But plenty of high-speed I/O operates
at much lower voltages. Many of those special cases require
secondary regulators on the motherboard. The DIMMs have secondary
regulators. And the CPU uses "voltage of the week", as up to a
certain point, the CPU voltage was dropping to around 1V for the
core, whereas with Haswell, Intel bumped the external voltage
back upwards, while internally the FIVR regulator of Haswell
made a very precise voltage for the CPU core.

The power supply also contributes to system operation,
by delivering a signal called power_good, and the
ATX motherboard won't run until power_good is asserted.
The power supply then, monitors successful power supply
atartup, and tells the motherboard to go ahead after
around 35 milliseconds or so. The laptop adapter
doesn't do that. (There is no separate wire in the
harness with a power_good on it.)

*******

The constraints on the laptop adapter:

1) (almost) no intention to power primary systems from the
DC voltage selected for adapter operation.
2) Upper limit on DC voltage set by SELV. In appliances you're
not allowed to use excessively dangerous voltages, without a
lot of extra protection mechanisms. For example, it would be
"very efficient" for the laptop adapter to just rectify the
AC line voltage and deliver 300V DC or more over the adapter
cable. But that value would be higher than is safe. Even with
extra insulation, and safety disconnect features, there would
be too much insurance liability for a company like Dell.
3) The higher the voltage, the lower the cable current, and the
thinner the cable can be (until SELV or similar rules force a thicker
insulation to be used).

So when the adapter makes 19V at 3 amps, the 19V doesn't run the
disk drive motor. All sorts of secondary regulation is on the
motherboard. What the 19V can be applied to, is the battery
charging circuit, providing enough headroom to implement
the constant current/constant voltage charging phases for
the battery chemistry. If the battery is nominally 14.40V,
a 19V potential makes a reasonable choice for building
a charging circuit.

The other thing the laptop adapter can have, is a more precise
current limit. Since it only outputs one voltage, the
circuit is better controlled. (On the majority of ATX
supplies, the transformer turns ratio establishes the
voltage relationships, and the feedback mechanism
responds to the movement of all outputs at the same
time. It's actually very sloppy, and has an relatively
large cross-loading spec to allow for a heavily loaded
rail to adversely affect the lightly loaded rails, and
the system still works.)

Due to the quite-different purposes and design requirements,
it helps to have a different name for them. Even if people
don't initially realize that it might be important.

I certainly wouldn't have made the distinction above, without
being forced to think about it :-)

Totally different and limited purpose.

An AC adapter in the case of the early reply to replace the power supply
(i.e. replace the laptop power supply - battery or ac adapter ) is not
even relevant.

Yeah. When I communicate, I try to use terminology that is relevant
to the USER in HIS context. It does no good to argue irrelevant issues.
So, the answer to my question was simple...NOTHING is not relevant...
but to remove the double negative to make it easier...It was ALL relevant.
Happy nitpicking...
