HP Dv6648se not posting

Anyway, even though I'm still nub when it comes to computers, I offered to help my coworker with her laptop, an HP Dv6648se laptop. She says it's out of warranty, so I'm assuming it's about two or three years old.

Anyway, her first problem with it is that her adapter died. (I forgot to ask her it her laptop was plugged in when that happened.) Anyway, I found a new one on eBay for her.

Problem is when she plugged it in it won't turn on. I have it in front of me right now, and I've reseated the battery and cleared any static on the CMOS battery by removing the main battery and holding down the power button for thirty seconds. I plugged it in--with the new adapter--and noted that the blue light around the plug is on. However, when I hit the power button nothing happens. No activity at all.

I insert the battery, and with AC power, still no activity. Unplug the AC, still no activity. Is there anything I'm overlooking? Any known quirks with this laptop? As far as I can tell, the RAM and HDD are seated fine, and I have no easy access to other components so I'm not going to touch them.

Or is it just borked?

 

Does it have nvidia graphics?

If so, is it 8400m or 8600m?
Those have the known faulty core.

did you use a DMM to test the old AC adapter? Maybe it was fine.

EDIT: known quirks would be that it gets hot. So if it has the faulty nvidia GPU, you get this result.

 

GPU is Intel X3100, according to the stickers.

As for hte old adapter, the point is moot since she already got a new one.

 

I would take it apart and reseat everything. Check for any shorted pins. Anything that looks burned.

 

I'd rather not disassemble things if I didn't have to. So, considering that she had not opened the computer herself, it would mean nothing has come loose or been improperly placed.

I guess it's borked then.

 

The same exact thing happened to my friend's laptop - his wouldn't turn on either but blue light next to AC plug was on. Solved the issue by lending him my notebook battery and switching it with his, and the computer miraculously booted. Hope this works for your coworker!

 

Interesting. I thought a notebook should boot just fine if the AC is on and the battery is out. I'll see if she has a spare battery.
