Laptop Power Supply

[markisbond]

It depends how you is your computer.  What happens is the voltage is converted from AC to DC and the transformer (inside the little black box) emits heat.  If your computer is fully charged AKA close to near 100% then your power supply should remain cool.  If it is actively charging the power supply will be hot.  It's sucking two times the juice meaning more voltage is being converter resulting in a heat.  

Do not hide the power supply under clothes and make sure there is air freely to move around.  HP should have design this to automatically cool itself with ambient air.  

If its always hot even at 100% charge then you must have an issue.  You can also listen to your A/C Adaptor (I know weird) and you can notice a big difference when using it for charging or using it for just simple power.

Good luck.

My wife's HP G60 laptop has a power cord that says to replace with part #463958-001. It's the 65W power adapter but she would occasionally receive a pop-up on the laptop saying that it wasn't the best one to be using (even though that's what it was sold with) and that we should upgrade to a higher power adapter. I put off looking into it for too long and now it won't power the laptop up so I need to replace it. I read this post and responses and it looks like I want the 90W power adapter) possibly part #613153-001). Does that sound right? I'm concerned with the 4.74A that that one would upply vs. the 3.5 that the current (now dead) one was supplying.

Can someone confirm for me that appropriate substitution? I would like to move to the one that the computer actually needs rather than replacing with the same, incorrect, one that HP packed with it - and is it me, or shouldn't HP be sending the correct power adapter rather than an incorrect one and having the consumer pay to replace it? We convenintly didn't start getting the pop-ups until after the computer was out of warranty.

Oh, and this power adapter also gets very warm, but then so does the whole laptop...

I have a HP Dv-4 1124nr and have had it for 3 years.  My power cord has always run hot and I guess it concerned me but ignored it because so did everyone elses.  Today, although I was supposed to be running errands, I stayed put instead.  All of a sudden my power supply caught fire.  Thank God I was here.  I unplugged it but the wood floor it was sitting on was also on fire and had to extinguish it (after unplugging of course).  How scary was THAT??? I  am calling HP and the BBB and reporting this.  This is 1 of many I've seen here catching fire.  This is a MAJOR probelm and if HP doesn't take responsibility then I will.  Don't leave these plugged in.  I will NEVER by an HP laptop again.  This many years and they are obviously ignoring these complaints.  go to thier website on thier power replacements and they say right on it how hot they run.  HELLO HP!!!!!   

I have already begun this process.
