How do you diagnose and replace faulty components after water exposure?

1 Turn off and unplug

The first thing you should do is turn off and unplug your computer immediately. This will prevent further damage from electrical shorts and corrosion. Remove the battery if possible and disconnect any external devices, such as keyboards, mice, or flash drives. Do not try to turn on your computer until you are sure it is completely dry.

4 Test and replace

After you have cleaned your computer, you can test it to see if it works. Reassemble it and plug it in, but do not turn it on yet. Check if any lights or fans come on, or if you hear any beeps or noises. If nothing happens, you may have a faulty power supply, motherboard, or battery. If something happens, but your computer does not boot properly, you may have a faulty hard drive, RAM, or keyboard. You can try to troubleshoot these components by using another computer, a USB drive, or a diagnostic tool. If you find any defective components, you can replace them with new ones or take your computer to a professional repair service.

5 Recover and backup

Finally, you should try to recover and backup your data if possible. If your hard drive is still working, you can connect it to another computer and copy your files to a safe location. You can also use a data recovery software or service if your hard drive is damaged. If your hard drive is encrypted, you may need to enter your password or use a recovery key to access your data. You should always backup your data regularly to avoid losing it in case of water damage or other accidents.
