Just got a Compaq Presario F700 laptop and the only problem is the jack where the power supply plugs in. It's loose, and I currently have to position the plug a certain way for it to charge (which the battery sucks, but I'll pick one up off ebay cheap). My question is about the jack. Do you guys think this would do: Ebay: Compaq Presario F700 Power Jack

Could I just get one of those and have a repair shop solder it in for me? Or does anyone have a better idea?

The only other alternative would be to get it replaced by HP, which should cost a bomb. :thumbsup:

Assuming it is a good quality jack, be sure to get it done by a professional (laptop repairs).

Yeah, having it replaced by HP is not an option. I'd like to keep my arm and my leg. :thumbsup: BTW, what do you think someone might charge to install the jack? Rough estimate?

Sorry, I do not have the faintest idea.
Err...Would $50 be too little? :S

I usually get a flat $120 for replacing jacks (parts and labor). Be careful supplying your own part and expecting a shop to install it. Either they won't do it, or will not give a warranty on user supplied items.

$120 to replace the power jack? Like ReviverSoft said: around $50 sounds alot more like it. I only have $25 and a few hours of work in the thing, so there's no way in hell I'd pay someone $120. There's also no way that I'm going to take it to a shop that refuses to repair the thing using the part I bring them. They just want to supply the parts so that they can mark up the price and profit from that on top of labor charges. If they flat out refuse to do it that way, they're probably trying to screw you over anyway. Was gonna do it myself to save some cash, but disassembling a laptop is a whole other beast compared to dissecting a desktop. A refurbished USB/Power Jack on Ebay will run me $24 flat (not a fan of refurbed goods, but...), or I can get it directly from HP for $47.50 + S/H. Which do you guys think would be better in the long run? I also need a new battery too, but HP, TigerDirect, Newegg, etc. want $95 for that (even though the factory battery pack is a worthless POS), so needless to say I'll be picking up a new 12 cell battery from Ebay for $35-45. You know, I could even live with the power jack problem, but the heatsink and stuff needs a serious cleaning, so I might as well replace the jack while I'm in there. Heatsink is producing a massive amount of heat and causing it to shutdown after about 25-30 minutes. I have the repair and service manual for the F700, do you think this is something I should attempt myself?

Well, you better jump on anyone who will do it for $50. Disassembling a laptop down to the motherboard, resoldering a socket, and putting it all back together, is a 2 hour job (flat rate). Where I am from, that is $100 in labor, and a flat $20 for the jack (saves time on quotes). Look around online and see what places charge to replace broken power jacks.

If you have the service manual, do it yourself by all means. Great learning experience. Keep all of your screws organized, inspect the board for delamination of the traces under/around the socket. Get a small screwdriver set, and a pick set is handy to pry up/unsnap trim panels. A little socket set/nutdriver set is handy for removing the retainers for the sockets on the rear of the case. Learn by doing.

As far as a shop warrantying your part, why would they? They have no idea if it is an OEM spec part, they have no idea who made it, or it's history. If I supply the part, I know it is OEM, and if it doesn't work, I am the one who screwed up the job.

@dpunisher: If I can find someone who will do it for $50, I'll jump the bleep on it. Don't think that this is something I wanna try and tackle myself, as I have absolutely no experience disassembling laptops. Damn, even cheap computers turn out to be f*ckin' expensive! But, since I'm totally against tearing this thing apart myself, is there a way that I can clean the heatsink without taking the whole thing apart? Got severe heat coming from it (apart from a can of compressed air, I just use an air compressor set to a low pressure level).

That's true, I guess you need to spend that much (~$100) after all.

Yeah, I guess stripping a laptop down to the mobo will be something better left to a professional. Christ, I hate to spend that kinda cash on a $25 computer.

Its really not that hard to do as long as you have a service manual or directions telling you how on how to do it.

As long as you use extreme caution, its not that hard of a task, its a learning experience and you'll save a bundle on top of it.

If you'd like to give it a go, let me know, I can provide you with instructions with pictures included.

Bruce.

@ MrBruce1959: Yeah, I think I'm going to go for it myself. I already know how to tear my desktop piece by piece and reassemble it, so it's time to learn the laptop.

Yes, Bruce, any help that you could offer me would be much, much appreciated brother. Thanks again, man. :thumbsup:
