DV8000 65watts PSU heating issue

Hello every one...

I bought my dv8000 (dv8125nr) a few week ago from BB and every thing is working great and we're still loving it.

Battery last about 2 hrs or so, and takes the same amount of time to charge it back up.

The issue that I came across is not the notebook itself, but the PSU.
It seems to get really hot when charging the battery or when I put the CPU on a full load while I was testing the laptop.

I call HP and first talk to some one here in the US, but I didn't have my laptop with me and didn't know what the S/N is.
I call back a few hr. later and talk to a tech in India. He was very helpful and is sending me another PSU w/o charge or give them my CC # to have this one send back.

I was wondering if any one notice the accessive heat the PSU is putting out. (65 watts)
verheat: This has got to be about 115-125*f. Hot enough that you can't/don't want to hold it in your hand for more then a second.
If the heat is normal, then I think HP needs to up size there PSU to a higher wattage.

I also know that they have a higher wattage one (95watts or so), but that's an optional item.

I'll just have to wait and see when I get the new one next week and I'll let y'all know.

Edit: To test and see how hot your PSU is or will get.... either use your batter down until it prompt you that the battery is low then plug in to charge.
Or you can put a full load on your CPU. I do this by running fold@home or Seti@home. Let your CPU peak out for about 15-20 min. or so then check to see how hot it is.

 

I've got the same dv8125 notebook (I couldn't resist the Best Buy sale either) and my power brick gets warm, but that's about it. I also get far more than 2 hours of battery life. I just fired up SuperPI, disabled undervolting, and so far the brick is still merely warm.

Replacing your power brick is a good idea. It's also possible that there's something wrong with your notebook itself, such as a faulty motherboard voltage regulator, but hopefully a new brick will take care of everything.

10+ minutes into SuperPI and my brick is still just warm. I can hold it in my hand easily.

 

Pretty much the same results I get - warm to the touch, but not burning hot. When I get home I'll try to get a temp on mine.

 

I haven't run into any deals in that in a long time. For the setup/cofig, you can't beat it with stick.

Anyway, how long does your battery last until it prompt low battery or go into hibernate.
Can you use your battery for a few hrs then plug in your PSU and see how hot it'll get?
Better yet, while it's charging. Run your CPU at full load, then see how that feel.
I'm hopping that it's just the PSU so I don't have to return and get a new one from BB since I've already load all my apps on it already.

Thanks in advance for your help.

 

Hey Kondlao, thanks for your help over in the other thread. As far as the chargers go, my dv brick is always cool to the touch. Don't have to worry about leaving it sit on the table or the leather ottoman. The zd on the other hand was a way different story. You could fry an egg on that thing, not to mention it is nearly 3-4 bigger than the brick shipped with the dv. I exchanged the zd for the dv after reading all the threads in here and I'm very much glad I did.
