I own a 19.5 v charger for my sony laptop, but when I tried to use it, the device wouldn't boot. I borrowed a friend's charger, and it worked. The issue seems to be with the charger itself—it shows 18-19v on my multimeter, yet the laptop still won't start. The readings fluctuated between 18.9v and 19.3v before stabilizing. What should I do?

During tests using a multimeter with a load, it indicates the power source cannot maintain the proper voltage when operating under load. This means a replacement is necessary.

Yes, you're suggesting I purchase a fresh charger.

Disconnect the noisy cord and test another socket. If the noise continues, employ a voltmeter to check the cord's voltage.
