Machine in trouble: Acer Travemate 3270 running 512MB RAM and WIN XP SP3. Symptom: When power button pressed hard drive light lites for about 1 to 2 seconds at the most then turns off. I have replace: 1. Power Board DC Jack 2. LCD Inverter board because there were vertical bars when the machine was dying. 3. External battery. 4. Power supply less than 1 year old.
Could be corrupt cmos, bad hard drive, bad memory, bad peripheral.
Remove hard drive and perform diagnostics on it to make sure it is good and not the source of issue.
Then check to see if machine is posting - if not, then you are in deep doo doo because without a posting procedure you cannot repair your OS, install a new one, nada.
A new mo bo will set you back 100 bucks on ebay: installation of mo bo on laptop is one Royal,, Royal PIA.

It's a little more involved than just removing the keyboard. You have to
Completely disassemble the laptop, until just the motherboard is in your
hand.
HOWEVER, for this Acer model it's a different installation, than the
normal one. This DC Power Jack uses a small wire harness. You just
unplug the old one, and install the new one. Let me explain,
I'm a tech who normally works on HP, Compaq, IBM, (Lenova now),
and Acer laptops. Acer's that are older than yours. All the DC Power
Jacks that I have replaced, are directly soldered to the motherboard,
and have no wire harness leading off of them. No plug connector on
the end of a harness, either.
In my search just now for a replacement power jack, my findings show
that the Acer Aspire 5920 series have a small wire harness.
Let me show you,

Here the jack is offered minus the harness. You have to unsolder your old
harness from the defunct power jack, and solder it to the new one.

You'll find the body of the DC jack is made of plastic. There is a metal
pin in the center. (This is the Positive post. + )
Some DC power jacks have a metal cylinder, or metal tube shape that surrounds the Positive metal center pin. This is the Negative connection.
Some just have a flat metal contact prong in the back for Negative.
If you have your AC adapter plugged in, and the plug is bumped, the metal
center pin can break loose from it's mount. Break loose from the plastic
body. Same thing for the metal 'shell' for the Negative connection, but this
doesn't happen as often.
Again, most DC Power Jacks have metal flat prongs that come out of the
power jack's body, go through the motherboard, and are soldered on the
backside. These solder connections can crack, and break, making an
intermittent connection. Doesn't seem to be the case for yours, IF the
jacks shown are the correct ones.
This may help you in your endeavor to disassemble your Acer Aspire.
(AND reassemble!) (TIP from me. DEFINITELY buy an ESD wrist strap
and connect the alligator clip to a good ground. They only cost about
$5 to $7 dollars. They are to relieve static from your body. Electro Static
Discharge wrist strap)

Have you tried attaching an external monitor when the LCD screen is disconnected from the motherboard? this connector is located under the keyboard strip – a piece of plastic just above the keyboard.
If it works, this way, then the video cable isn’t seated properly in the connector on the back of the screen.
Plugging the video cable back in should fix the problem.
I don’t know how comfortable you are with taking apart laptops but I think that this information could be useful for you.

Do the following without the battery inserted.
Let the computer sit with no battery for 24 hours. Do not put the battery in at all. Try using your original memory stick ONLY, with no hard drive and see if it will POST. If it does, insert the hard drive and try again. Could be the new memory...
Another thing you can try is reseating the processor. Turn the ZIF screw, take the processor out (WATCH THE PINS!!) and put back in GENTLY. Leave the memory in the computer, hard drive removed, try to power on.
These models have been known for bad motherboards. Contact HP and arrange to send it in. If you do enough digging on HPs website, you'll find the service advisory.
