Using a Lower Rated Adapter: Potential Damage to Laptop and Battery?

AI Thread Summary
Using a lower-rated adapter (19.5v 3a instead of 19.5v 4.7a) for a laptop can pose risks, including potential damage to both the adapter and the laptop. The lower amperage may lead to the adapter being overloaded, which could result in failure. If the adapter fails, it has the potential to damage the laptop or its battery. While the battery may charge more slowly, the risks associated with using an inadequate power supply outweigh the benefits. Caution is advised when considering using a lower-rated adapter.

So, I find myself without the AC adapter for my laptop and I need power.

My adapter is rated 19.5v 4.7a.

I have an adapter from an older machine (same manufacturer), rated 19.5v 3a.

The physical connection to the laptop is the same.

Will I damage the laptop and/or the battery if I use this lower rated adapter?

Or will the battery simply charge slower?

Insufficient information to tell you anything certain.

There is a good possibility you would damage the lower power adapter as it gets overloaded.
If the adapter fails it could damage the computer.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
