I'm... (still) almost shocked to see people recommend disconnecting the battery, not to mention rinsing / baking the keyboard... In a MACBOOK  :palm: :palm: :palm:

In many other cases (ie. "real" laptops, not glorified tablets), yes, but... Well, how's that gonna help the OP, i wonder?  ::)

i accidentally droped tea mug,with hot tea.into my my macbook air 13.
That is what you should do. Yes, the screwdriver is not common so taking it to somewhere who can and ideally then displace the water has the best chance of saving the laptop from a serious repair. What do you mean by "glorified tablets" because the MacBook Airs were some of the best laptops around before being superseded by the useless USB-C MacBook.

Nice machines (I've used one for a project) but hardly user upgradeable unless you're handy enough with a screwdriver to strip it down (which most/all of us are, end users, not so much) and even then I think you can only upgrade the SSD?

Not quite a tablet but pretty damn close in terms of expansion options so glorified tablet is a snarky but fair description IMO.

Ehrm... What exactly do you mean by "best"? ::)

Coolest running? Not even close, quite the contrary, in some cases.
Highest-performing? Hell naw.
Best bang-per-buck? Hardy-har-har  ;D
Spill resistance? Ehrm...  :-/O
Build quality?


Battery life? Ok, i might give'em that.
Displays? Fine, maybe that too (although the utility / practicality of over-fullHD in a 13-15" screen is arguable)

The MacBook Air is was the best in its category. No, the screen of the MacBook Airs are not the best (terrible TN panels), but their performance for their size and weight and build quality and battery life was not matched by other Ultrabooks at the time.

I have the original Spectre and its battery is quite poor; its SSD (SATA, AHCI) is no where near the my 2013 Air's.
The WIfi is not as good, either.
No Thunderbolt on the HP, either.

Now, if you're comparing their MacBook (2015) and Pro models to others then there are trade-offs too, but I do not have as much personal experience with them so will not comment aside from I think they are overpriced but have features that other laptops do not so you have to objectively look at it from a user's specific needs.

I'll say this much about Macbooks... at least you can just take the bottom panel off and all your stuff is right there.  HDD/SDD, cooling, RAM, main board, battery.  Getting sick of the trend in PC laptops lately where everything takes a near full disassembly to get even to the HDD or RAM.

Yes it's right there, behind that bathtub shaped swimming pool (when it gets wet) that empties all over the logic board, behind the wall of funny screws and then when you get there, it's soldered to the motherboard because you couldn't afford the more RAM option.

That's because they're shitty PC laptops.

Every ThinkPad T/X series I've serviced requires a single Philips driver to strip it to the bone and it takes 5 minutes flat. Every damn Macbook right back to the G4's is a cross between Jenga, defusing a bomb and doing a Rubik's Cube with one hand behind your back and an eyepatch on.

That's great if you're in a corporate/controlled-issue environment and the ThinkPads are standard issue - sadly out in the consumer world they're few and far between relative to what arrives daily.

Guess we have different perspectives on the Macbooks; I don't find them any worse than the majority of PC laptops, and as mentioned before. The single lid access is a boon, as you say, 5 minutes and you've got them stripped down (sure, I have to have a torx and/or pentalobe on hand, but that's standard for any workshop anyhow).  Would be nice if they had some drain holes though...and fans that didn't scoop up the liquid offerings.

This oldie is a goodie ( to be fair, there aren't too many worse than the DV5 series )

I sell used ThinkPads to consumers so problem solved ;)

Hadn't seen that. Quite funny!

This is the thing I last did. Someone brought me one of these bastards (this is not me btw): - chassis deformed, caused left IO board to crack, which shorted out the magsafe connector which promptly went up in flames.

Oh damn, those nasty old things;  I don't ever work on anything older than Core2Duo Macbooks... and even that's a push since most of them aren't worth the cost of repair.

I can't complain much about the "accessibility" of my Dell Precision M4800 either  ::) Remove the battery, and the whole bottom panel comes off with two Philips screws  :-/O

My preliminary list of questions, measure voltage on:

PP3V42_G3H
PPBUS_G3H
PP5V_S5
PPVRTC_G3H
PP3V3_S5

and tell me if you get a light on the charger, and we'll go from there.

I understand that Louis and others are frustrated from dealing with stupid customers all the time, but it seems insulting their intelligence to act as if they believe sticking rice on corrosion is going to heal a phone. No one thinks that or ever thought that. The rice reasoning was an attempt to remove water from the phone as fast as possible and prevent corrosion damage. I'm not saying that there aren't better ways to do that, though because there are. However, the desire to remove the liquid from the device is complete rational and is "denial" or the belief in magic. The sarcasm that always accompanies this topic seems unnecessary and a bit demeaning.

What do you guys think? Am I missing something here?

Facts can't insult or demean, only tell the truth! And they are indeed true. I stopped attempting to debate or educate people who walk in years ago on the rice thing. They will argue until blue in the face that rice fixes their phone. I smile knowing I'll be seeing them in a week for a $400 data recovery rather than a $100 cleaning or something, and wish them the best of luck. It doesn't pay to discuss until I am blue in the face when the person arguing with me is telling me "I'd rather do something that makes no  sense now so I spend 4x as much money later"

There is no point in removing the liquid. It's actually better that the device stay in liquid. If you got your phone wet, rather than put it in rice you should encase the entire thing in water until you can get it ultrasonic'd somewhere with the shields off. The liquid itself doesn't do the damage so much as the minerals and garbage in the water when it finally settles, after it begins to dry.

So, to repeat: YOU DO NOT WANT IT TO DRY!!!!

So, even if rice hastened the drying process, it is only helping kill the device further by quickening the pace at which a clump of green junk will land on top of an important IC/solder ball and begin corroding it.

Either way, once opened and cleaned, we can get to troubleshooting and actually fixing it. So finish eating your rice and get to work. :p

The exact same principle applies to heavy equipment affected by flooding. It is best that it remains immersed in water until you are ready to disassemble it, give it a full cleaning, and displace the water. It's very surprising how slowly corrosion happens when fully immersed!
