Got this Acer laptop that's acting up. When I first turn it on, it will boot
normally and then after about not even a minute, its shuts off.

I tried the following:
-With the battery only,
-with the battery and ac adapter
-and with just the ac adapter

And it still does the same thing. And sometimes it won't turn on, using
either of the methods above.

I noticed that the laptop's DC power jack is a bit loose (well, not loose because its not soldered on to the motherboard like others are, its the type of DC jack that's connected to the motherboard via a plug/wire). But with the AC adapter plugged in, I can wiggle it from side to side and up and down.

I took the laptop completely apart, and cleaned it really good with a can of compressed air. There was quite a good amount of dust bunnies hiding inside. I also thought that maybe the dust was creating the problem and
making the laptop overheat and thereby shutting off. But even after cleaning it, the laptop still shuts off.

I don't know what else to try, so I'm hoping someone here can help me or guide me in the right direction.

Thanks guys...

Forgot to add that the battery light in front of the laptop blinks orange continuously when the laptop is actually on.

Hi

Try as much of this as you can, you have probably tried some of it - Black Screen Issues and Troubleshooting

UPDATE: I noticed that the charger is not the correct charger. Its not putting out the correct output. Gonna try with the correct charger and see.

My cousin says he bought the charger on eBay. The guy he bought the laptop from didn't have the charger. So I guess he purchased the wrong charger.

Has the laptop always given problems since the purchase of this charger?

Look at the base of the laptop. There should be a dc rating. Check that the power adapter has the same dc voltage rating. If you can check the output with a voltmeter or borrow if possible a genuine adaptor for test.

Good point you bring up, I checked the DC rating on the bottom of the laptop and the output rating of the charger is less than that. But again, whats weird is that he said when he got the charger the laptop was fine.

Regardless though, I told him he needs the correct charger to rule out the charger as the problem. Would you agree?

How much of a voltage difference are we talking about? The genuine charger would be need to prove if it was a power issue or not.

In the mean time, how old is this laptop, has the cooling system ever been cleaned out, how is the laptop operated i.e. on the lap, taken to bed, on a carpet or on a flat surface? This information is crucial.

Try as much of the procedure as you can from the link I gave you.

The charger from ebay says 19v 1.58a, and under the laptop it says DC Rating 19v 3.42A; and I took the laptop completely apart as I mentioned in the original post and cleaned it with a can of compressed air. There was a good amount of dust inside and mostly around the heatsink and fan. As far as how it's used, he says he uses it mostly on his computer desk, so on a flat surface.

The ratings on the laptop are the maximum ratings and the charger should also match this.

After market chargers are made from cheaper materials and quality control is not at the same level as the OEM version.

If you were to check the voltage with a voltmeter you would probably measure 19v but as soon as the unit is put into service it would start to deteriorate under load or even normal running. Remember the maximum current rating quoted is when the charger has to run and charge a fully discharged battery. I have known these type of units to melt and smolder when they go defective.

Thanks for the info. So would you say the charger is causing the power issue? Or until I try with the correct charger there's no way to know?

Its highly possible, does the charger feel very hot to the touch? They will get warm when charging a battery, what I'm looking for is exceptionally warm to hot, but carry out the procedure in the mean time first.

Actually, it's very odd that the charger is cool to the touch even after being plugged in for hours. I haven't actually tested the output using a multimeter, don't have one handy.

At the moment it could be a number of things, thats why I want you to carry out the procedures in the link first.

Well, I'm an electronics tech and I use the Fluke range of equipment and the ones I use will break the bank.

I'm assuming you are in the US, I am in the UK. Ask yourself what would YOU want a multimeter for and how often woould you use it. I will then have a better idea what you need.

UPDATE: I borrowed an Acer charger from a friend who has an Acer laptop and the charger happens to match the exact voltage output and dc rating as my cousin's laptop. I plugged it in, and it worked fine. The laptop started rite up and never shut off. It charged the battery and I was even able to run the laptop on battery only after the battery was charged.

So I guess this fixes the problem with this laptop. Thank you night_shift for all your help.
