Discussion Overview

The discussion revolves around finding non-proprietary power cords for an HP15 laptop, addressing issues related to power supply functionality and potential damage. Participants explore the nature of power cords versus power supplies, and the implications of proprietary designs.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about non-proprietary power cords for their HP15 laptop, questioning whether the issue lies with the cord or the PC itself.
  • Some participants suggest that power cables are generally not proprietary and can be sourced from local computer parts stores.
  • Others argue that the HP15 being a laptop may imply the need for a proprietary power adapter, as connectors and voltages vary across models.
  • Concerns are raised about the specific design of the power connector, which may not accommodate standard cables.
  • Participants discuss the importance of measuring the DC output with a voltmeter to diagnose the problem.
  • There is mention of the power supply functioning intermittently, with some outlets working better than others.
  • Questions arise regarding the parameters to consider when purchasing a new power adapter, including voltage and connector specifications.
  • A participant shares their experience of finding a universal charger that works, attributing previous issues to potential damage from frequent handling.

Areas of Agreement / Disagreement

Participants express differing views on the proprietary nature of power cords for laptops, with some asserting that they are not proprietary while others contend that they are. The discussion remains unresolved regarding the exact cause of the power issue.

Contextual Notes

Participants highlight the lack of standardization in laptop power supplies, noting that voltage and connector types can vary significantly. There is also uncertainty about the specific nature of the power issue and whether it is related to the cord or the laptop itself.

Who May Find This Useful

This discussion may be useful for individuals experiencing similar issues with laptop power supplies, those seeking to understand the differences between power cords and power adapters, and anyone looking for recommendations on purchasing compatible power supplies.

Hi all,
I have an ailing powercord in my PC (HP15, Win8.1 64-bit). Last I checked, powercords were proprietary, i.e., designed specifically for a given brand, if not brand model). Does anyone know of non-proprietary cords that may work for my PC?
EDIT: I would also like to know where the problem is: is the cord damaged or is the issue with my PC? Other than the obvious idea of trying other power cord (that is not an option at the moment) what can I do to determine where the problem is?
Thanks.

Power cables? Like the cable that runs from the wall outlet to the power supply in your PC? I've never had a proprietary power cable. As far as I know just about any power cable out of the surplus bin at your local computer parts store should work.

Wait, after looking up the HP15 it looks like it's a laptop. That's a bit different. Those might be proprietary. I know the power cable for my old laptop won't fit in my new laptop, as I tried it recently.

Thanks, but there is a circular input node for the power cable and it may not fit the diameter of just any power cable.

Does the power cable also have a transformer ("wall wart") that actually plugs into the wall outlet?

This is a power supply, not a power cable. It turns AC into DC, and is specific to the laptop. Neither the laptop's voltage nor connector is standardized across laptops. If you Google "HP-15 power adapter", you will see many options.

They look to be fairly inexpensive to replace:

Have you measured the DC output with a DVM? How do you know it's bad?
Hi, thanks for your reply. The issue is that when the computer is plugged, the PC is using the battery, i.e., battery is being drained out even when the Pc is plugged into the wall socket, i.e., the power is not "going to the computer". I don't know if the issue is with the computer or with the cable. I noticed the connector part of the cable (please excuse my ignorance of this area, and the main terms) does not heat up when the cable is plugged in.

Strange thing is that it works on-and-off, and in some outlets but not in others. Thanks, I will do a seaarch on "HP-15 power adapter".

No, it only has a three-prong plug into the wall, not sure of the technical name, I am embarrassed at my ignorance in this area.

Do you have access to a voltmeter? That's the best way to figure out whether the power brick is still working. Also, the cord and connector will not heat up, but the brick itself should get warm when charging.

And since you say it seems to work with some AC outlets, use the voltmeter to check the output voltage as you move the brick from outlet to outlet.
When you plug the adapter into the HP-15 laptop, and click on the battery icon, does it indicate it is charging?

Wait, so it really is just a cord? Not like the images of the HP-15 power bricks that I posted earlier in this thread?

My bad, sorry, it is one of the ones you described.

Do you know the main "parameters" to look out for when buying one? I am in kind of a hurry and would like to buy one from a local store. By parameters I mean, e.g., the parameter of the input node, voltage, etc?

There's the output voltage and the actual connector that plugs into your laptop. The latter tends to be proprietary, though, so your best bet is to buy one online that is specified for the laptop.

Thanks to all; the (extremely boring) saga is over. I found a universal charger and it is working, albeit at a pretty steep $65. Anyway, a caveat : I remembered I had been doing a lot of "coffee-shop hopping" for a few months, and I suspect that all the folding and unfolding of the charger (to deploy and pullback when heading out) may have damaged it somewhat. Thanks again.
