1 | My HP Pavillion laptop is not holding its charge. Is it likely to be the charger or the laptop itself? cary14 - 2020-12-06 13:42:00 |

3 | Very simple to check the charger with a multimeter. nice_lady - 2020-12-06 13:47:00 |

I wonder if a multimeter would be in most peoples tool kit ? I somehow do not think it would be. perfectimages - 2020-12-06 14:05:00 |
5 | $11 at jaycar. Or ANY sparkie will take about 30 seconds to confirm power adaptor output for you. Why would you not do that before assuming it's the battery at fault or anything else. Edited by nice_lady at 2:14 pm, Sun 6 Dec nice_lady - 2020-12-06 14:14:00 |

7 | Hmmmm....let me see there is no water in my swimming pool. What's the logical thought process here to figure out why? Hm... If so then either no one put any in the pool, or it leaked out. If not then more than likely the pool is fine if we can restore the water supply. Not to difficult to work thru. Edited by nice_lady at 2:47 pm, Sun 6 Dec nice_lady - 2020-12-06 14:46:00 |
8 | I do not think your analogy applies in this case because you were assuming in post #3 that a person would have a multimeter (or know what it was, let alone how to use it). I contend that most people would not. One of the first things I learnt when I was learning to teach was to think that most people were like Sgt Shultz "that they know nothing". If you are going to take on the role of giving advice (ie. teaching) it not only has to be accurate but also be easily understood by anybody. Please do not think that what is easy or obvious for you, is easy or obvious for all. It may get you into trouble to varying degrees.

9 | #3: had no such assumptions - it was a simple statement of fact. And you'd are completely incorrect in your belief that I have no teaching experience. Particularly in this field. Edited by nice_lady at 4:29 pm, Sun 6 Dec nice_lady - 2020-12-06 16:27:00 |

After 20 years of in home tech help for people who were largely very lacking in knowledge about their computers, and many of whom refused to have anyone else I would suggest to you to just go away from this line you are spinning. nice_lady - 2020-12-06 16:46:00 |

I was not questioning your knowledge or ability with computers (which I know is very good) but I think that maybe I was suggesting that you might like to adjust the way that you pass on that knowledge so that it does not come across as so condescending as it sometimes does. perfectimages - 2020-12-06 18:45:00 |
13 | I don't need your advice nice_lady - 2020-12-06 18:59:00 |

15 | Perhaps instead of nitpicking you could offer the OP useful advice related to their problem rather than hijacking this thread. nice_lady - 2020-12-06 19:22:00 |
16 | Well most of you are correct on saying this lady does not have a multimeter. Just wanted advice really. cary14 - 2020-12-06 19:48:00 |
17 | Yeah and what I said stand. It's a process of elimination. Any sparky has a multimeter. And it would take about 30 seconds to tell you whether the power pack is faulty or not. You need to know this. nice_lady - 2020-12-06 19:55:00 |
18 | you could take the battery out if it's a removable, that would soon tell you if the power supply is the problem king1 - 2020-12-06 20:23:00 |
19 | That's quite right but a lot of newer models the damn thing has to be half dismantled just to get at the battery. nice_lady - 2020-12-06 20:33:00 |
20 | It is normal for laptops over 5 years old or so not to hold their charge very well depending on how the battery has been treated. Unlike car batteries they are better if the lithium batteries are kept at half charge. If the laptop keeps working with the charger connected then the charger is working. No multimeter required!! duncb - 2020-12-06 21:32:00 |

I have had much help from Nice-lady and experience her as understanding and patient with my limitations, i have never felt she was being condensending, but knowledgeable and helpful. I am thankful for her. Edited by omaria at 11:23 pm, Sun 6 Dec omaria - 2020-12-06 23:21:00 |

Correct - IF the description 'not holding charge' is correct. It's possibly a good idea to check if it's getting charge first. nice_lady - 2020-12-07 06:20:00 |

Possibly not but a confirmation of correct output voltage would be a simple start. We went thru this exact scenario with Hubbys HP Laptop recently. And buying an $11 multimeter from Jaycar solved the issue. nice_lady - 2020-12-07 06:21:00 |

Thank you omaria. Y'know what we say around here: "omaria - not again" ???? nice_lady - 2020-12-07 06:23:00 |
27 | Everyone should learn at school how to use a multimeter. The no load voltage should be the same as the load voltage as it is a regulated power supply. tygertung - 2020-12-07 06:46:00 |
28 | Didnt there used to be a way to make a laptop reset its battery level estimates? Would that help? emmerson1 - 2020-12-07 21:07:00 |

Yeah my kids are familiar with a similar saying combined with rolling eyes. I told you I was born in the wrong era, my brain has not been fine tuned to technology,but im great in other areas, so I guess I cant win them all. omaria - 2020-12-09 10:00:00 |
30 | Hey you do alright. After all you found us ! nice_lady - 2020-12-09 10:23:00 |
31 | And I am so glad I did and all the helpful advice over the years. :) omaria - 2020-12-09 16:27:00 |

33 | You didn't read post #27? And in our case it wasn't meaningless at all - the multimeter showed voltage problems with the power pack. So your assumption isn't relevant in all cases. Edited by nice_lady at 9:22 pm, Wed 9 Dec nice_lady - 2020-12-09 21:19:00 |

35 | All this multimeter talk is most likely an overkill and irrelevant. If the charger will power the laptop even if the battery is flat then the charger is 99% likely to be ok. OP have you tried the HP Diagnostics to test the battery? Power on and hold the Esc key until you get the startup menu. Press F2 for system tests. If the full range of tests are still on the drive you can test the battery under "Power". But if you only get Memory and Hard Drive tests then you cannot test the battery from that menu. However you can download the full tests. Just google "HP diagnostics" and take it from there. Edited by cookee_nz at 10:06 pm, Wed 9 Dec cookee_nz - 2020-12-09 22:04:00 |
36 | For us the HP diagnostics said failing battery, (oh and be aware thete is an issue with some HP batteries and they're running a free replacement program). The multimeter showed us that the power pack was flakey and faulty with inconsistent output. We replaced it for $65 from PbTech. All good. Battery still screwed but the power pack runs the machine fine. Edited by nice_lady at 6:02 am, Thu 10 Dec nice_lady - 2020-12-10 06:00:00 |
