RE: Fujitsu Siemens Amilo li1705 Freezing when Moved
Yep, the only proper way of fixing the bad nvidia solder is to do a 'reball'. A reflow only works for 6 months at best.
The problem is not overheating: the problem is that the lead-free materials, which nVidia's design engineers have chosen to solder the chip to the board, are not capable of dealing with heat cycles. A bit of an oversight for a consumer computer chip. This is just another example of the lack of internal manufacturing knowledge with nVidia, which has haunted them all their lifetime (anyone remember their RAMDAC trouble?). So a 'reflow' is only a temporary fix, if you are lucky you get another 6 months out of it. The permanent fix is to 'reball', i.e. replace the solder with something more suitable. There's a guy in Peterborough who bothers with this, he's got videos on youtube :-) Reflowing can be automated and done on an industrial scale, but reballing can't, so it isn't cheap :-( However, reflowing can be a great way to recover data from an encrypted hard disk where the encryption is system-board specific.
We really could do with a preview/edit function on here... I meant to say: " HP/Compaq business laptops are ace, that's not where the problem is. The problem lies with nVidia's chipsets, not with the laptop brand. Simply avoid any system that has nVidia chips in them, and you will be fine. nVidia has had design-for-manufacturing, production and quality trouble since its inception. "
I offer local computer support for professionals and small to medium size businesses around Northamptonshire.
New clients like you start out by contacting me as and when they need help. After we work out what, if any, work is needed, you will get a fixed fee quote.
It's then up to me to see the work through to its conclusion, within the fixed fee, and within the agreed time.
