391 Extra Battery Tested

Welcome to a Laptop Ac Adapter specialist of the Apple Ac Adapter

I have an acer aspire 5315 and when I boot it up with the power adapter plugged in nothing happens. Then when I boot it up using only the battery power, it attempts to boot but this only lasts for a few seconds and shuts off again.any suggestions on what might be wrong?

Check AC power that AC power cord and adapter can be replaced from online vendors cost is pretty cheap. I own two ACER/GATEWAY laptop and ACER Netbook both use the same AC adapter. To test your adapter you need what is called a multi- AC/DC tester it has positive and negative leads. If you don't want to get to technical you can replace the AC power adapter.

Your model AC Adapter B001MQ694W if you need to replace it that battery like Apple A1021 Ac Adapter, Apple ACD55 Ac Adapter, Apple M4402 Ac Adapter, Apple M4896 Ac Adapter, Apple M5937 Ac Adapter, Apple M7332 Ac Adapter, Apple M8482 Ac Adapter, Apple iBook G4 14 inch Ac Adapter, Apple iBook G4 14.1 inch M9165LL/A Ac Adapter, Apple PowerBook G4 1.33GHz 12.1-inch DVI FW800 M9184LL/A Ac Adapter, Apple PowerBook G4 1.33GHz 17-inch DVI WideScreen FW800 M9110LL/A Ac Adapter, Apple PowerBook G4 12.1-inch M8760S/A Ac Adapter is on this link too. Both are really not to expensive. You should always have a replacement battery and AC power adapter around just in case of problems like this one.

Also if it's not the AC adapter or battery then you're looking at a defective MOBO (motherboard) or defective HDD. This laptop would need to be troubleshooted though to make sure what's the issue could be. But with the above info you should be able to figure most of what the issue could be

When we reviewed the Acer Aspire S7-391, we loved the gorgeous industrial design and 1080p touch screen. But one of our chief complaints was that the Ultrabook’s battery lasted just 4 hours and 10 minutes on the LAPTOP Battery Test (Web surfing via Wi-Fi). That’s 2 hours less than our ultraportable category average, and hardly what you want to see out of a $1,699 notebook.

Fortunately, Acer released an external 2,500 mAh battery that promises to extend the S7′s runtime considerably. How did it fare on our tests?

The external battery extended the S7′s life to 9 hours and 17 minutes, about 5 hours longer than the battery in the notebook itself, and about three hours longer than the ultraportable average.

Unfortunately, the external battery attaches somewhat awkwardly to the S7. You have to screw the battery into the bottom of the notebook, and the plug it into the S7′s power port. The plug itself juts out about 3/4 of an inch, which made us worry we’d accidentally snap it off. It also increased the weight to 3.4 pounds, up from 2.8 without the battery.

However, the battery did alleviate one problem: In our initial review, we noted that the front edge of the Aspire S7 dug into our palms. With the battery attached, the rear of the notebook increases about 0.75 inches, which tilts the front downward, and no longer digs into our hands.

The battery costs $150; unlike the smaller Acer Aspire S7-191, it’s not included with the notebook. For this kind of money, Acer should bundle the external battery. It’s not pretty, but it supplies the kind of endurance you would expect from an Ultrabook.
