I just bought new battery and it’s my 3rd time buying my ac adapter. my ac adapter always get extremly hot and when my laptop battery is going low it take about 2 hours to charge it back up to 100%. Usually it takes less thant 40 minute to charge it back to full charge. Anyone knows what’s wonrg. Sometimes my air vent on the bottom of my laptop get hot too even though I do not cover it up too.

2 problems there:
1) if it’s running Windows, it will never get great battery life, 3 1/2 hr. MAX!!!
2) heat can also make the battery not run as long. I recommend one of the cooling pads.

Also… Are you sure you have the correct AC adapter?

Laptop batteries can be overpriced and not always get you the battery life you need. Hot ac adapters are fairly common computers and laptops. Even if it’s new, you may have gotten a bad battery. Refurbished batteries usually have a 30-day warranty and cost a small fraction of the price as new. You might search for a refurb battery for your laptop just to confirm that it is the battery that’s the problem and not the laptop.
