Inspiron 1545 won't power up with battery

I'm wondering if my laptop's battery is no longer any good: it won't
power up with the battery connected and supplied external power, but if
I remove the battery and just use the external adapter, it powers up
fine. Dead battery? How can I tell for sure? Thank you!

If you disconnect from the external power, does the computer just die or
keep on keeping on?

Obviously it will die without the battery present because I removed the
battery.

Does the battery have a charge on it? Is it shorted? Can you try a new
battery?

If a new battery works, you might need to check out the charging system
if the old battery wasn't charging. If the old battery was shorted or
otherwise not taking a charge, well then you need a new battery.

A repair shop may have good batteries and a multimeter to do this kind
of troubleshooting whereas a normal user might not, if you don't have
those things, bringing it to a shop is probably the best course. I'm
not sure about your model laptop, but there may be a switch which is
actuated by inseting the power plug which is also a possible failure
point.

Not what I meant. Power it up with both connected. Once you're booted
up, remove the external power supply and see if the battery will keep
the computer on. If not, time to replace the battery, assuming they
still make them. I have an Acer and the battery died. Acer doesn't make
the batteries anymore.

Well, this is strange. Earlier, when I first tried to start up this
laptop for the day after being off all night (other than plugged into
the AC adapter), it wouldn't power up. The light would come on and the
fan would start, but then it would just go off. I then removed the
battery and used the adapter only and it powered up fine. At one point
of course while on AC only, the cord came out and everything went off.
I decided to re-insert the battery. This time it powered up fine with
both power and battery connected. I have since removed the power and am
currently on battery only as I type. The battery meter shows a tad over
3 hours left, which is what it should be and so far it agrees with the
minutes I have been on only battery. So, why the laptop acted the way
it did earlier I don't know.

I don't either but I'm glad to see it's working now.

Still going for half an hour now. No AC power, just battery. While the
battery was out, I did see that the manufacture date was 2012, so still
getting aged. If I had to replace it, I don't have a clue as to where
I'd get one. I know, Dell is the obvious choice, but I see batteries of
this type with wildly varying prices, sometimes 3-4x less than Dell
original.

It's not clear if this is the case, but if the battery were completely
discharged, it's possible the laptop wouldn't power up until the battery
had acquired a certain charge level. In any event, let it fully charge
and run another full discharge and charge cycle.
My 2010 Dell laptop seems fine so far, although it isn't used all that
much.

Jacks on laptops get lots of abuse and sometimes the connections gets
loose. Next time it happens, try jiggling the plug/jack.

When batteries get discharged below the "safe level" determined by the
protection
circuit, they take steps to disable themselves.

Sometimes, if it's not too far gone, you can disassemble the pack,
charge/balance the cells and
get it working again.

I had one that seemed ok at first, but after a lot of head scratching,
I determined that it was behaving predictably...predictably undesirably.

With the battery removed, the laptop ran normally.
With the battery installed, the system ALWAYS RAN ON BATTERY.
With the AC plugged in, and powered on, the system claimed
it was charging, but was not. It would run until the battery
ran down.
With AC plugged in, battery installed, system powered off, the
battery did indeed charge.

I decided that this was a design decision. Make it so irritating
that you would buy a new battery, but not leave you completely
stranded.

Problem with laptop batteries is that any "new" battery was probably
manufactured about the same time as the one you have and has been
sitting in a shipping container in Arizona for a decade. There are many
anecdotes from people who's "new" battery behaved poorly or not at all.
Paying retail price may get you the same crap you'd get for cheap on ebay.

I have a big pile of working laptops. I have almost no working
batteries. I've spent a lot of time attempting to remedy that
situation with little progress.

Have you tried a google search with "batteries [mylaptop model]"?

There might be some resellers that have batteries compatible with your
system even if not "made" by Acer.

My Acer isn't used enough to justify spending any money on it.

I just looked up acer laptop battery on Amazon.com. They start at only
$10.87, and don't go much higher.
