Hey everyone,
I just got a HP dv7-1253ca that reads "plugged in, not charging" with the battery. My first thought was "battery is shot" but I'm beginning to second guess myself. My reasoning being:
a) the battery has zero charge, it won't even stay on for 1 second.
b) the battery charging light stays on then blinks 3 times then goes solid again.
c) the actual ON light to the left of the battery charging indicator is either not on at all or very dim with or without the battery in.
I should mention everything on the computer...

HP dv6 - Power on, Power off
DAUT1AMB6E0 rev E - Anyone have a schematic?
Powers on, fan spins, power led comes on, then it all shuts back off. I tried a reflow on the graphics chip, south bridge and north bridge but no change. Based on my limited knowledge I suspect there's a short somewhere and the power supply is killing power.
There are two thing I've noticed so far. There is an LED (LED9) by the left edge of the board between the HDMI port and the E-SATA port. When I first plug in the power and push the power button, it comes on and then goes off with the rest. Every time after that it... -

Re: dv9000 Wireless Issue
Good news! It works. Turns out my testing methods were flawed. I'm positive it wasn't working after the GPU reflow. I booted into windows and the card wasn't detected by 3DP Chip. I booted into linux and there was no mention of it in the kernel logs. After that, however, to speed up the testing process with the different wifi cards and reflows I was simply booting a linux live cd and checking if there was wireless detected. I should have been checking the kernel logs. I just did and it detected a broadcom wireless card, but didn't have the driver to enable...Leave a comment:

Re: dv9000 Wireless Issue
The motherboard is a DA0AT9MB8A3 rev A. Anyone have a block diagram and/or schematics for this board?
This board doesn't appear to have a north bridge so I'm guessing the north bridge functions are built into the CPU? There's a smaller nvidia GPU next to it. The block diagrams I've found for dv9000s (obviously not the same as this one) show the wireless pci-e going into the north bridge. I'm curious if the wifi on this board is going into the cpu or the south bridge.. or the gpu?
Also, I'll have to read into mini PCI-E but how...Last edited by andr3wmac; 07-24-2013, 02:31 PM.Leave a comment:

Re: dv9000 Wireless Issue
Nope, that's a good idea though. Just tried it and here's the result:
That's gotta be worth something right? At least it's detecting the wifi card and the fact it's not a supported one. Light is still solid orange and doesn't change when I flip the wireless switch on/off....Leave a comment:

Re: dv9000 Wireless Issue
Hah, that's funny, that was my next step. Still, not a very satisfying solution, but I've tried everything I'm capable of at this point.Leave a comment:

Re: dv9000 Wireless Issue
Went ahead and reflowed that chip. No luck. So I figured screw it, stripped everything off it, propped it up and put it in the oven on 375C for 7 and 1/2 minutes. Still no wifi. Everything else works fine, USB included. I've got copper shims in there, temps are good, just no damn wifi.
If reflowing the whole board didn't work does anyone have an idea why it isn't working? Apparently it's a common problem after they overheat. I've read of people fixing it by plugging the vents and using benchmark programs to heat up the computer. Surely baking...Leave a comment:

Re: dv9000 Wireless Issue
I'm guessing the southbridge is the chip near the actual wireless slot.
Is that the one? Should I reflow the whole area (chip+ mini pci-e slot area) or target the chip specifically?...Leave a comment:

dv9000 Wireless Issue
I have a dv9000 sitting around with dead video and decided to give it a go today. Reflowed the nvidia graphics chip with a heat gun and the video works fine now but the wireless isn't working. Operating system doesn't detect any cards (i've tried 2 HP wifi cards, same part number). Wireless light just stays orange whether the switch is enabled or disabled. No options to enable/disable in BIOS.
Any ideas? -
