I'll probably live to regret this.
If there are mods that someone wants doing then subject to the following I will have a go.
You provide all the parts
You provide the motherboard on which the parts need fitting
Nothing in a square package with legs on each side unless its only 20 or so pins, no BGAs, DIL are OK
Specific instructions
Your risk
Preferably UK only
I won't do hundreds of anything, I don't have time
Explanations.
Anything in a square package I have difficulty with because normally the soldered joints are too far underneath for me to see the soldered joints under my microscope, I have never succesfully changed a BGA of any sort. I am really only offering this as a means to proving the mods.
Mods like the 6000 Bluetooth look to me to be really straightforward whether by flying lead or by original component fitting.
I've no idea about Bluetooth or Wifi on a 3100, I've never seen a 3100. I own a 6000, a 5500 and I just bought a C860. The latter purely for the purpose of ripping to bits and messing. I bought the 6000 for that but it proved too much of an addictive article and I don't want to dismantle it.
I do a lot of laptop repair for a couple of local shops. This I only do out of interest and because Joe public is knackered if his laptop goes faulty and they have very few places to go , I certainly don't do it to make money though it does keep me up to date with a reasonable laptop. I have a full time job that provides income.
If there is anything specific that someone wants to try then I won't charge anything provided the return postage is not much otherwise I'd like the postage back but as I say this is not me trying to set a business up, I don't want that, it's me trying to assist where people can't do it themselves.
If your close to Burnley (25 miles North of Manchester) then you can always pop over and we can do it together.
