There is an alternate universe where every time he took his computer apart, he skipped the reflow heat stuff and just put it back together... and it worked identically for identical periods of time between failures. I'm not saying it's this universe, I'm just saying there is one out there.

Are you in my living room? A few months ago I disassembled and cleaned a grape juice damaged MBP. Tried it afterward and no dice. Tried it yesterday on a bored whim and I now have a working MBP with a sticky keyboard. Why? I have no idea.

I once spilled an entire glass of water into the keyboard of my macbook while it was on. It automatically shut off. I thought I was hosed. I almost smashed it on the table in fury. Luckily I didn't. I quickly removed the battery, took the computer COMPLETELY apart, and blow dried it for a few hours. It came back on and has been working ever since like a charm. Its been over 5 years now. Same with an iPhone 5s. I dropped it into a glass of water. It didn't work for awhile but came around after a few days and worked fine afterwards.

I wonder if it's worth the effort sure it may reflow solder if it's hot enough but the high temp lead-free solder or whatever Apple uses may require very high temperatures to get it to melt even a bit. I've changed enough capacitors on power supplies to know the damn things have solder that's practically indestructible, our old Pace solder station iron cranked to something like 850F and still I'm sitting there 5 or 1…

Often the issue is the component is sinking most of the heat away from the joint. If the giant chunk of metal your heating can dissipate the power of your soldering iron, you're not gonna heat much up.

True but even with the component removed and trying to clean up jagged solder on legs it's tough stuff to get to melt.

This is the solder that comes from the factory we just use the lead-free regular stuff when it goes back in.

Earlier quoted context omitted.

Over time, you're probably paying 2x or 3x in insurance premiums compared with what the loss would be. Consider also the overall effect if you invested the premiums instead of paying them.

I pay $45.00 a year for a $2,062, no-deductible policy on my MacBook Pro through State Farm. I'd have to have the MacBook for 45 years for the premiums to even equal the payout on loss.

22 years if you invest the premiums at 7%. (At 45 years you'd have $12,858.70.) Add this up for all the other non-catastrophic items you have insurance for.

I know when you're young 45 years seems like it'll never happen, but if you're lucky it does.

Take a look at any chart of the S&P 500 over decades. What matters is the day you invest, and the day you cash out. The wiggles in between mean nothing.

Buying another laptop doesn't change the math.

If you're consistently having losses that makes insuring you unprofitable, you're likely to see large escalations on your premiums. Insurance companies do keep tabs on this, and premiums are customized to the individual customer. You may be paying higher rates on car and home policies than others.

If you're well aware of the true costs of those choices, and choose them rationally, there's no problem with that.

Lots of people don't know that, though. The prof who taught me accounting used to work as a car salesman, and he told me that the money is made not by selling cars, but by selling financing to people who refused to understand what the financing cost them. (I say refused because he was a nice guy and would try to explain to them what it would really cost them, and they refused to even hear the explanation.)

I've been around long enough to realize the benefits of self-insuring as much as possible, buying cash instead of financing, and the benefits of long term investing and not worrying about the daily (or even yearly) gyrations in the market.

It's not a joke that dead people statistically have far better investment returns than live ones, because they just let their investments ride instead of trying to time them.
