Put new batteries in will not power up with batteries or power cord

So put the old power cord back on since you say it charged the battery normally. Why did you change it if it was charging the battery? It's quite possible that the new power cord is faulty. Just because it is new does not mean it works.

Remove the battery and plug the new power cord in. Does it boot the laptop up? Are you able to function with the new power cord plugged in. If so, then your battery is more than likely dead and needs to be replaced. The battery only has a useful life and once it is completely bad it will not charge.

Did you check the DC Jack where the Power Cord plugs into the laptop? If it is bad (wiggly or loose) then the laptop will not power on. Take an ink pen and put it where the power cord would plug into the laptop and see if the jack wiggles or is broken. If so, that's your problem.

The old power cord might be some good if the problem is with the DC Power Jack.

Maybe the AC Adapter Power Cord is not working. If you can't get on the laptop with the power cord then it is bad and the battery might be drained so you have no power source to power up the laptop.
If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.

To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.

To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.

Click Start Control Panel and go into the Power Options to check the Battery Meter. Batteries on last for so long. Maybe it's time you buy a new one.

Unplug the power cord. Remove the battery. Press and hold the power button for 60 seconds then release. Plug the power cord back in but leave the battery out and try to turn it on now. If it comes on you can put your battery back in. If it still does not come on you may need a new power supply/ adapter.

Most likely issue is that the cord has been damaged, or that the power jack has become loose.

First step is to remove the battery and try plugging in. If the light comes on, on the front of the laptop, your battery may be dirty or defective.
If the unit will still not power, you will need to test your cord or look into a new cord. If the cord puts out the proper 19v (give or take .5v) then the issue lies with the laptop jack. Otherwise a new cord will most likely do the trick.

well if it's a new battery and you're having issues send it back, you may need to calibrate your new battery with the laptop

Couple of things

First is to let it charge with the lid down for a few hours.
If that does not fix it then check that your son did not use the alternate display option FN F5 or FN F6 on the acers I think

If you still have no luck you might want to ask questions of your son before you take it to a repair shop

If you press the power button and nothing comes on at all then something isn't providing power to the laptop as it should and you may likely need to replace the battery or the power cord.

Find a replacement battery. Change your battery with a new one then plug it up and turn on to see if this works.

If replacing the battery doesn't work then replace the power cord and trying turning it on again. If this doesn't work either, you have a more serious issue going on.

Not too long ago, I was on vacation, my laptop had been working fine until suddenly it wouldn't come on at all. I went into the office to grab a new battery and power cord. (I work on computers so I had spare parts in my office/Tech Room.)

I got home and replaced the battery then tried to turn it on using the old power cord...didn't work. This was a brand new battery so now I knew that I could rule out the battery as the issue...the only two things left to troubleshoot were the power cord and the laptop itself.

I put my old battery back in the laptop then tried to turn it on using a different power cord and it worked. I didn't need to replace my battery or laptop. The power cord had failed.

I hope that your issue is as simple as this solution. Try confirming whether your battery and power cord are still working...you may just need to replace one or the other.

Thanks for using Fixya.

I had a similr problem It turned out that the power supply cord was not the problem, it was the main battery. Luckily, in 2000, I bought 2 extra main batteries. I took out the old battery and put in one the 2 new unused ones and my machine is working and charging perfectly now.
