Laptop issues. Need ideas

I got my laptop fall 2007. Its HP Pavillion dv6400 something or other.

One day my battery was running low. So I plugged it in. This laptop has a light ring around the charge input so you know whether or not it is plugged in. This turned on BUT i noticed the battery icon on the taskbar was not saying it was plugged in. It eventually ran out of power and shut off accordingly. There are also lights on the front to tell you if the computer is plugged in/charging/fully charged. This light as off.

So I took out the battery and left it plugged in to trouble shoot the battery. If I'm not mistaken, a laptop can power on without a batter if it is plugged in. This didn't work, so I assumed it was the power supply.

I bought a power supply for like $15 bucks. Plugged it in, little plug-in light turned on, laptop did not turn on. Tried this with and without the battery.

So now what? The only logical explanation I can come up with is that something is disconnected between the plug-in input and the rest of the computer. Ideas?

How long did you leave the new plug in before turning it on? Takes a bit to build up minimum battery from dead.

Also possible that you have a power connector loose on the mobo

Well its not as easy as something getting unplugged inside. There are multiple components to a charging unit. I would guess one of the transistors blew from a power spike or something. You have warranty on it? It would probably need internal repair.

better idea than mine. warranty is your best bet, if you have to get it repaired it might not be worth the trouble and cost

Hate to be the bearer of bad news ptriz21 but you've fallen victim to the now famous HP motherboard recall.

You plug the computer in, turn it on and all the lights light up but the screen is black right?

Unfortunately Nvidia released some defective GPUs in those models that overheats and they melt the motherboard (no you didn't read that wrong) only way to fix it is to send it back to HP.

They will extend your warranty, read more here: http://h10025.www1.hp.com/ewfrf/wc/d...name=c01087277

I've had so many people at my office with this issues it's insane, hope everything works out for you!

Wow I'm using my fiancee's dv6000 for now and I was wondering if that's why it would get ridiculously hot. When I was trying to install XP the laptop would shut itself off 30 seconds into the install because it was too hot. But the service tag doesn't match the ones with the issue, so I guess not. I'll probably update the BIOS just in case though.

^ Yes update the BIOS immediately!

It updates the code for the GPU fans so it doesn't overheat, it'll save you a lot of headaches!

Man it's a good thing I saw this, I mainly use the comp for this 3D modeling class, so the GPU is definitely being used well.

Re: Laptop issues. Need ideas

I was on that warrant page a when i was first diagnosing my laptop. I guess it helps to read the whole thing

This makes me happy. Though I'm aware that the process of warranty repairs suck, at least I'm not completely out of a laptop.

Yipes...

I guess I should be happy then that the only thing my TX series HP laptop does is get real hot once the hardcore graphics stuff is used (my MB has the ATI 3200 mobile chipset, run anything 3d graphics wise and the fan goes into o/d but the cpu still can spike to 87C :shock
