My laptop charger keeps shutting off?

So I just bought a used HP dv7 laptop. It came with a Dell charger and was able to charge fine. I use my laptop as my home computer so its always plugged in. Since I always keep it plugged in, I removed the battery so over time it wouldnt kill the battery life.
So everything runs good, but I also like to play games on my laptop. when I do my laptop shuts off. I thought it might be my laptop crashing, but I noticed that the small light on the charger was off. I unplugged the charger from the wall socket and plugged it back in and the light came back on and my laptop powered up. The charger was very very hot. So I pointed a fan at it and played the game again, but it shut off again.
I thought it had to do with the dell charger and the HP laptop, So I bought a brand new HP charger. But it still does the same thing, the charger shuts off.

Is there some settings I have to change? or something wrong with my laptop?
I cant figure it out.

It's possible that using a Dell charger on the HP laptop damaged the laptop. It's my understanding that Dell laptops and Dell laptop chargers are designed to be compatible only with each other. Different laptop manufacturers use different power supply types and power settings to make their products proprietary. Even if the charger fits I wouldn't recommend using it. There could be subtle differences in the electrical frequencies which might prevent the charger from charging the laptop's battery or damaging internal components if the battery is removed. The wrong charger could very possibly end up damaging the laptop.

To me it's kinda, sorta like buying a Chevy but trying to make Ford or Dodge specific parts work. Yeah, they might fit, and they might actually work for a while, but . . .

Normally in HP Laptops the shutting off of the charger when the battery is fully charged is quite normal. Happens with my HP also but not with Dell Laptop where the charger remains always on.

But my battery isn't in my laptop. My laptop is plugged in with no battery, since I didnt want to kill the battery life.
So does that mean that my laptop, is telling my charge that the battery (which isnt even in my laptop) is full?

I know you said you're using a Dell charger on the HP, not the other way around. But Dell chargers have a small microchip inside them to let the Dell laptop know that it's an official Dell charger. Using a non-Dell charger on a Dell laptop could permanently cut the laptop's processor speed by 50%. It's equally possible that by using a Dell charger on your HP you may have permanently damaged the HP. This previous Forum thread talks a bit about using non-compatible chargers and laptops. I'd specifically ask you to read Post # 4.

Can HP charger be used for Gateway laptop?

Ahh yes I read through that thread. and re-read post #4. But there are so many mix answers. But I hope that my laptop isnt borken...

@Takaaaa: So, you're running your laptop off of AC with the battery removed - right?

I've thought about doing this myself, but instead I've been running off of the battery and recharging as needed to cycle charge the battery.

Try this - put the battery back in, let it charge and see if the machine shuts down when you play the game. I'm wondering if your power settings need to be adjusted - don't know exactly how you would set them, but changing the "on AC" settings might help down the line. Please post back. Thanks.

Yes that is correct. And sorry i forgot to add that. But since i ran my laptop off just the charger, when the charger shuts off, my laptop would to. So I put my battery back in so that when the charger shuts off, it wouldnt shut off my laptop since it would just run on the battery.
So I was playing my game with the battery and I would tell when the charger shuts off since the icon at the bottom would change from plugged in to just battery. I was able to play until 10% battery without it shutting off, but I had to keep unplugging my charger from the AC and plugging it back in to charge my battery while I was playing my game.

@Takaaaa: The other thread was a red herring - post# 20 (jloc: Sorry, I was wrong).
Ok, so the battery is in, the charger is on - then the charger (new HP charger) shuts off and you're running on battery fine until you reach the low or critical battery level - right?

All right, let me ask this: what is the machines behavior when not playing the game? I don't think that matters much, but I'm curious. I think you might consider changing the battery - it was a used HP right?

Not necessarily a red herring but I did amend my post due to conflicting thoughts. Point is, I do not and will not recommend mixing HP products with a Dell, or an Acer with a Gateway, or a Sony with whatever. If people wish to do so, then it's on them if something breaks.

The odd thing is that your machine shuts off when running on AC only because the charger shuts off.

Yeah the thread was very confusing to me. haha
Yes that is correct.

It runs perfectly, no problems at all. I took my battery out again and right now Im just running off my HP charger. I have been on all day and no problems at all.
Yes, I bought this laptop used. I'll call around and see if I can get my battery tested.

I just assumed that since I had no battery and just running off AC power, that when the charger shut off, it cut off power to the laptop, so it shut off too.
