I didn't remove the logic board, but I took a look at it and the DC board before I started this thread and didn't see anything obvious. I don't know the layout of the board to determine the location of pertinent components, so I didn't bother tearing down far enough to look at the "bottom" side of it.Oh, sorry to hear about that! - Next steps are more challenging.
I'd look inside the PB if any part is smoked off. Last year I've got a 17" PB with non-functional trackpad and some keys. Replaced the top-case, but only the keyboard was ok after that. Then I detected a tiny thingy on the mainboard that did look oddly "burnt" and broke off after a gentle Uspudger's touch. Maybe you'll find something like that either (hopefully) on the DC-in board or the logic-board, before you start to look for a DC-in-board replacement. Cheers
BTW: did you check the charger on another device?
Do you happen to have another pb to verify the functional state of your 65w charger? If you don’t (I didn’t) a gentle wiggle side by side would produce intermittent connectivity thus lit ring. Anyhow, just trying to ensure it’s not something simple before you start looking at lobos & other internal components. Best of luck.
Good call to both of you on checking to make sure the new charger works. Alas, though, I tried it on my 12" iBook and it does indeed work. Sadly, this third party charger doesn't have a ring to light up, but no biggie on that.
I've done some looking and it looks like I can get the DC-in board for around $11 shipped from PowerbookMedic. Sadly I'm only seeing one logic board available on eBay right now for more than double what I paid for the laptop.
So, I'm wondering how much of the charging/power circuitry is on the DC-in board, and whether you all think there is a chance that it could be the culprit. Also, just in case, if you know of any better source for a logic board, please let me know! I can't justify spending $190 for one. PowerbookMedic lists them for $54.75 but they're out of stock.
When your 'Book suffered charging component failure, what did you end up having to replace?Right, I get that.
But having had a HD-DLSD where I ended up using a 45W charger for a little over 6 months before realizing it was 45W and not 65W and then a year or so later having complexing charging problems I can speak to the reality of it.
It won't happen today, tomorrow or possibly even next year but it can ultimately cause some charging component failure. There is stress being placed on the system.
