cannot power "on" ASUS laptop after power outage

That said, if there's suspicion that the original ASUS power supply
had issues as well, I'm not sure exactly what to recommend without
looking into it deeper.

Just where is it you think ASUS gets their supplies made?

System: ASUS N61JQ (laptop)
Host OS: Ubuntu 12.04 LTS


After a power outage yesterday, pressing the power button of
ASUS laptop does nothing. The laptop was/is connected to
an APC battery backup (surge protection only) outlet (via AC adapter).
AC adapter's green light is "on".

Any ideas?

I did a simple google search...

https://www.google.com/?gws_rd=ssl#q...er+requirement

It yielded listings for where to get replacement 90W adapters, but
scrolling down the page shows a lot of chatroom queries surrounding
problems with this particular laptop and its batteries and power supply.

It also lists the circumstances under which the failure modes are
occurring.

It would appear that the battery "watchdog" circuitry Asus
incorporated into at least this model of their laptop line has some
problems.

A slight dip in the output of the power adapter or even too much
ripple voltage presented by it when loaded may be what is going on.

The new ones seemed to only be $12 to $15. It might cause less hair
loss to simply get a new one. It is always nice to have backup power
supplies in the "dongle" or "wallwart" realm anyway, since most are
ultrasonically sealed and unserviceable.

Thanks (NumeroUno), you're right. A new AC adapter did the trick.
Nothing else seems to be wrong with my laptop.

But, the reviews for the Antec NP90 that I bought is not that great and
was not cheap ($40+). But, it has AQ3 (3-year parts & labor) warranty.
Any Universal 90W Notebook Power Adapter 19V recommendations?

Also, how can I prevent this from happening again?
The problem is with the power circuitry internal to the ASUS laptop, right?

More info ... the Antec NP90 gets quite "hot", which is a bit worrisome.
But, good news is that the battery pack seems to be in good condition.
It took about 45 minutes to fully charge. And, battery feels cool to the
touch,
which is good to have as little heat as possible.



Also, how can I prevent this from happening again?

The Lenovo 90 Watt unit is nice, but you would have to put the right
output plug onto it.

From what I was reading, that seems to be the case.

Likely no fix other than to feed it with good, clean DC power.

Probably got warm topping off the battery, and you probably had the
unit up and running at the same time.

Could be lower power than it is actually rated, OR it could actually be
doing a better job and is exhibiting more heat due to the heavier
initial charge cycle while running.

I'm surprise that they don't have that ac adapter plug connector better
standardized.

They are standardized, but the maker gets to choose the one they want
to use, and the plugs/jacks are not tied to a specific voltage to be
fed, though there was a push toward that end in the beginning of the
standard.

They are in metric and Lenovo uses the biggest I've seen, and likely
the right one for 19 Volts, but the other 19 V laptop makers might argue
against that statement since most of them adopted a slightly smaller
choice.

So, there is a standard for the plug sizes and center pin diameters,
but they are not tied to or standardized against a table of voltages.

There are 5 and 12 volt "typical" choices, but they too are not set in
stone.

AND 19 Volts is a non-standard (as it were) DC supply source, so there
is no plug size designated for it at all.

This one is 135 Watts. Would (may) only need an output plug
changeout.

And no, the wattage does not have to match the original. More is
better. It is just a declaration of what the supply is able to provide.
Your device still uses only what it uses. It merely has a better
likelihood of providing a cleaner DC feed, and exhibiting less heat
while doing so.
