The first thing you should do is turn off the device and take out the battery if you can. Liquid damage can corrode the system boards inside the machine when the liquid meets an electrical current. If the system has no power, it can’t burn out
For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced within 18 months. We recommend buying a new laptop battery when the run time does not meet your needs.
Even if your device can no longer turn on we can almost always get data from liquid damaged devices. Liquid damage primarily damages keyboards and motherboards/logic boards, but the hard drive is typically saved.
