HP 8710W No power - need schematics

[spleenharvester]

As title. Board isn't in my hands yet but will be soon. Anyone got the schematics?

Cheers

Re: HP 8710W No power - need schematics

need motherboard code. If compal LA-3331p, it is hard to find.

Re: HP 8710W No power - need schematics

That looks like the one mate yeah.

Hopefully it's just something simple like a blown MOSFET. Otherwise without the schematic I'm gonna have trouble with this one I think lol.

The board is completely dead apparently. Should be a bit easier to work with than those sodding non-POSTers I seem to stumble upon.

Ah well, I bought it for £20 with a presumed working Nvidia Quadro FX1600M and a T7700. So if I get it working, it's a bonus. If not, a good source of parts

Re: HP 8710W No power - need schematics

Eugh been looking for about an hour, I am sure these schematics are NOWHERE apart from those 10$ each sites. :/

EDIT: Pretty sure they can be had from some Chinese site (http://www.tbenben.com/plugin.php?id...page&aid=16941) but I can't get past registration.

Re: HP 8710W No power - need schematics

Guys, made some progress. When plugging in charger the LEDs light up etc. No power. Not many voltages round the board. Found 3.3v, 19v and 0.1v in various places.

The Intel 82801HEM Southbridge gets VERY hot. Clearly something related to that.

Cheers

EDIT: Found a very small hole in the top of it with a small discoloration. I have a feeling it may have gone up in smoke.

why cant you get past registration? seems pretty simple, just use chrome and translate it

There's a validation question on it, and translated it doesn't make any sense.

Eitherway, I'm now 100% sure the 82801HEM is knackered. If I bought a new one with balls pre-attached and used a heatgun to solder it, would it last long-term?

Re: HP 8710W No power - need schematics

That chinese site looks like it could be useful. Does anybody know the answer for registration? The question translates by Chrome as "is a fake horse repair network that the company LOGO? (Tip Chinese, what horse)". It doesn't translate well. We need one of our Chinese speaking members to help.

Re: HP 8710W No power - need schematics

Indeed! Then the problem is it has to be properly translated back to chinese :/

Although I no longer need these it would be nice to get them out there, clearly very hard to find.

Might give the board away to somebody because this is something an IR rework station could probably make light work of. And I no longer have time trying to reball etc.

ill try asking a friend if you can post the untranslated q up, or it looks like you can log in with a qq account

I think the answer is "dark horse" but, as you say, it probably needs a chinese translation for the answer box.

Thankyou very much for this mate! Just came back to harvest some components off this board and this is a big help. Cheers

Same problem
HP ProBook 4520s XT943UT schematic needed. please anyone?
Thanks

Re: HP 8710W No power - need schematics

Should be this:

Check to see if your SB or NB are getting hot. Then check your always on voltages.
