I spilled tea on my laptop, what should I do?

Question

Do it yourself

Friends, tell me please in the correctness of actions. I will add that the arms are not quite straight, but not from the tip either.
I filled the laptop with tea (it took half a cup, maybe a little less), the day before yesterday. While climbing for the battery, he abruptly turned on himself, did not have time, but he pulled it out anyway and immediately dismantled it. Fully. I left it to dry for half a day, then carefully wiped it with alcohol, even flooded some places on the motherboard, to be sure. Klava completely bathed in alcohol. For the second day, already dismantled, it stands and pulls with alcohol.
Tell me right away how much I am a turkey, will he live at least minimally based on the above?

Answer 1

In principle, it’s okay, except that it dried in vain, it was necessary to immediately rinse it out, until hardly soluble deposits had formed yet. While you waited, the moisture oxidized everything.
Wash everything with alcohol, after washing, dry with a hair dryer and blow with a cylinder of compressed air.
Remove the processor heatsink, remove the processor from the socket and make sure that there is no moisture in the socket, similarly check the other connectors, unhook and rinse / blow through.
Wiring harnesses are also worth checking, moisture could accumulate in the braids.
It is better not to wash the cooler and hard drive.
If there is important data on the disk, then turn it on for the first time without a hard disk, for example, boot from a liveCD, make sure that the beech is working normally.

The whole trouble is that neighboring tracks of the board, adapters from side to side, or simply the conclusions of parts can degrade gradually , a month, a year, after which they will fail. Before flushing the board, it was necessary, without panic, to very carefully find out where the tea exactly got and where it didn’t. Now, because you "covered up your tracks" it's not so easy to find out. Alcohol, of course, removes water with sugar, but you need to know what kind of alcohol you have, ethyl alcohol, propanol, whether there are additives in it and whether there is water in it itself, i.e. what concentration is it? By the way, in repairs for cleaning the board, they can use special liquid for cleaning in an ultrasonic bath, and far from ordinary alcohol. Because it is not known what and how it was filled in, what and how you cleaned - it seems that no one can tell you anything definite. I have outlined the risks.
I will describe a similar case. I used my smartphone very carefully, knowing about all the dangers of reading while eating, etc. And so, somehow I put it on the table vertically, drinking tea, which in 99 cases out of 100 I drink without sugar. It was this time that I made tea with sugar, and this time a sheet of plastic lying on the table stuck to my hand, knocking over the cup, after which the tea gushed in a stream soaking the bottom of the smartphone with the connector .. Perhaps the tea did not get further than connector housing, but I saw plenty of corroded boards, so I considered the 1,500 rubles paid for flushing to be the minimum evil. This is much better than possibly changing the whole board...

Microcircuits are often belly soldered. There is a gap between it and the board, it turns out a capillary. You can try to wash out from under them again with pure alcohol (it will be like a drying agent, 95%, and better anhydrous).
Under the usual and under the processor socket, they can also remain. It would be necessary according to GOST (as they joke) - to bathe entirely in 95% alcohol and more than once :) But we don’t even have it in stock at the pharmacy :( Vodka will not work - a lot of water, a bucket of hawthorn tincture - I don’t know.
Klava - there two layers of film. You may have to disassemble and wipe. If the tracks are damaged, conductive varnish or foil (haemorrhoids).
But the display is just not worth it with alcohol, you can wash off the polaroid (film), there will be something on the screen.
Maybe you can slightly vacuum at least vacuum cleaner, but without fanaticism (to dry faster).
Good luck.

The easiest way to save and clean a flooded laptop:
1. Go to any auto store and buy a few bottles of distilled water and a soft toothbrush in any other store.
2. Download the service manual for the laptop.
3. Completely disassemble the laptop.
4. If the keyboard has been flooded, you can immediately throw it into the trash and order a new one (in very rare cases, laptop keyboards after filling can be repaired - because they are usually non-separable and it is very difficult to wash them).
4. Rinse the electronics under a weak stream of distilled water, gently wiping the flooded areas with a toothbrush (do not press hard!).
5. Soak for a couple of days in a clean container with distilled water and a non-dusty room (you can cover it with something, such as cling film).
6. Repeat point 4.
7. Blow out hard-to-reach places with an air bottle (eg connectors).
8. Dry the electronics thoroughly for two days.
9. Once again blow hard-to-reach places with an air canister.
10. Put it back together, making sure there is no water or drip anywhere.
