I have successfully cleaned ME on VIT P3400 and it works great as long as the laptop never goes into sleep state, if this happens it is not possible to turn the laptop back on or turn it off completely since it does not respond to the power button, keyboard or mouse, nor to USB devices. It is necessary to disconnect the battery to be able to use the laptop again. It also happens that when you turn on the laptop, the CPU fan does not work, the keyboard and mouse suddenly stop working, and sometimes if you try to enter the BIOS or the boot menu the laptop freezes and does not respond to the power button.
It should be noted that these problems only happen if at some point the laptop is put to sleep, as long as this does not happen everything works correctly
