hiiii frnd im new in this group im need schematic diagram 10203-1 b560 laptop

The brand might help, but really you don't usually get schematics for compu ters. Fact is, the way they are, all you can do is change regulators and ca pacitors. Then some of them (in the words of a mobo manual I read years agh o) "hang permanently when the errors introduced by dirty power corrupts the BIOS past being able to flash. If it won't boot it won't flash. One of min e locked the harddirve in error, but that model harddrive was very suscepta ble to that problem. (WD1600BEVT, don't buy one)

You would be better off posting the problem you're having with it.

His machine is a Lenovo.

There are a few dodgy websites in Thailand / Malaysia / Vietnam that host free recent laptop schematics (pinched from the factory?). Takes a bit of googling.

Start with the word kythuatvitinh and don't do it from a Windows machine.

Heya,

TL;DR: stumbled here via:

there's also reflow'ing; "we" see a few laptops (particularly with nvidia chipsets) where this might be an issue.

then it might be worth using SPI or JTAG or similar . . .

"Computer Technician" apparently . . I *love* a "shady" tip . . .

walk on the wild side ;)

where this might be an issue. Got any more precise tips in that area? Temperatures and times and ramp rates etc. What's a good air temperature to use?

Lots of youtube videos, but not any detail on the numbers involved.

I built a fixture with a heat gun pointed at the bottom and another one on top. Managed to fix two of the three I tried. But it would be nice to have a better idea on optimum strategy. I have thermocouples on top and bottom, but Have not figured out how to couple the thermocouple to the chip. Any stress will cause the chip to move when the solder melts...not good.

Heya,

me? unfortunately not. anyone else? from my limited research (I have one candidate dell laptop which I've probably procrastinated over too long) its a quite unscientific process: mask off the surrounding area as best you can and wave the heated sacrifical chicken around a bit ;) . . . .

quite! I'd like to hear of anyones experiences, especially if the figures are backed up by e.g. spot IR thermometer readings compared to the settings on the heat source? also anything you did to mitigate it happening again (have you seen the comprehensive x-box shim, heatsink and paste kits you can get?)

blimey, hadn't though of this. pics?. but I'm guessing unless your doing a commercial repair, reflowing is a kind of last ditch effort, so just doing an edge (and only one side) at a time (instead of relying on the chip casing and PCH distributing the heat to all "pins" at once?) and crossing fingers is what most people rely on.

apologies for the pure conjecture . . .

I once got some SIMMs that were flakey, and looking at them, it looked like some of the soldering wasn't working.

So I used my heat gun, no attachment to direct that flow even though it did come with some attachments I've long forgotten, and that was good enough to get the solder going and I never had problems with those SIMMs again.

I think though, people use toaster ovens for such things. And I seem to recall, they are modified a bit for such purposes. Not a hardship, because toaster ovens are pretty common

interesting. and probably very profitable. at the peak of scarcity (8-16m b days?) they were worth more than their weight in gold. pitch size was proba bly significantly bigger and any supporting components on board were bigger and less likely to blow away.

and even hot plates. but only on single sided boards. "My" ((North)London ) hackspace decided to pledge for a cheap far eastern generic SMD oven as app arently the price difference versus the build quality and pain of "calibrat ing", timing, watching and guessing with a DIY setup is worth it, especially for a group. the purpose made ovens have preset and programmable temperature, time and ramp rates built-in. I think their size and the limi t of single sided boards make then great for small production runs, but jus t not flexible enough for a generic repair tool?
