NB Doctor is comprehensive, easy-to-use and fast
Easy, Comprehensive and Fast
Over 6 million people have used Phone Doctor Plus to test their phone hardware without needing a user guide.
Using the same design philosophy, NB Doctor can walk you through a test for your laptop.
An in-depth test
NB Doctor will test your laptop's every possible component from the keys in the keyboard to the internal temperature sensors to even the fans.
Play music and ask if you hear it or not?
NB Doctor uses your notebook's own speakers to automatically test its sound output.
Will it work in a noisy environment?
NB Doctor uses the same audio filtering techniques used in Phone Doctor Plus for over 5 years. With such optimizations, NB Doctor can work normally in a degree of noisy environment.
We use DSP technology for more than just audio signal processing
DSP is also used in by professionals in the industry for vibration detection and image processing. For example, to help detect stains on camera lens.
