  • laptop/power problem

    i noticed sunday that my laptop was running on the battery when the low battery light came on... i looked at the power brick and the green light was off, so i went and checked the breaker for that room... no breakers unplugged, so i unplugged my brick and tried the lamp plugged into the same outlet, light came on... so i unplug my laptop from the brick, unplug the brick, and plug in the brick again, the light came on... plugged in my laptop and all was good.... it did it 3 times since then, and just now my laptop died while i was transfering a few gigs to it from my desktop, and i touched the cord right next to the laptop plug, it was at least 115F (using a fluke meter with the temp sensor plugged into it touching the insulator on the plug end) i have two possibilitys... the power converter on the other side of the power jack is going/gone.. or there is an internal break in the cord (being a laptop, it sees a fair amount of being toted around, along with the brick since the battery has a shorter life than my attention span) anyone have any ideas here? since both are a bit of an investment id really like to make the right choice

    How long have you had this laptop?

    Sounds like your battery is at its End of Life cycle. You should look into replacing your battery with a new one.

      Tonk...

      I am actually surprised the battery is still going at all.

      you can get a battery for under 50.00, and the power supply is 20-25.

      the power supply is my first suspect. I have seen several short out. (this is especially true if the battery works at all.

      I think Acreo_Aeneas is correct - probably time to pony up for both though. - how has it been other than that?

        Re: laptop/power problem

        i bought a bat for 60 but it didnt work... i was rather pissed about that, it just blinked orange 5 in a row if i remember right... ran the system for about a 11 sec before powering off...
        otherwise been fine after replacing gfx card... and got a 1.6 or 1.7 and pin modded it to 2.26, gfx was overheating causing bsod.... havent had a bsod in 6 months now

        the wear level is only 55% using NHC's reading, idk if thats 55% life remaining or 55% life spent... either way the bat is half alive/half dead depending on how you look at it... any way to make the 250gb ata drive i have be able to use more than 137gb?

          I presume you're using XP on your laptop? The "137 GB" problem was fixed with the release of Service Pack 2 for XP. You might want to check that you have your OS patched to the latest. Also, on some boards, you might have to flash your BIOS to the latest version.

          If you've already tried a new battery, then look into a new PSU for your laptop. First thing is to check if you can get at the old PSU inside. If you can't, you'll have to send it into a shop to get the part replaced.

            Re: laptop/power problem

            nope, its vista.... the bios cannot address over 137... bios is the latest version A05 or A06, i forget. ive taken it apart, the power supply is easy to get at once open, which is easy to do too. i wouldnt mind just 137gb but if i make a 136 partition it wont even load the os once the os is installed
            and if i just make it a 250gb partition, it works fine until something gets put past that 137gb part

              Vista shouldn't have any problem installing into a partition of size 137 GB or larger. That whole problem was addressed in XP SP2.

              Was there one partition when you bought the lappy with Vista?

                Re: laptop/power problem

                Well, you're down to a problem with the laptop's power connection or the brick. Hope it's not a problem with the power connection in the laptop, because if it is you're down to about a 25% chance of it having a replaceable power board depending on the model. Otherwise it's a mobo replacement and you're better off buying a new machine unless you're handy and have a few hours to kill. Replacing the mobo is a DIY option but it's generally a ~$1-200 part and a 3-4 hour job. This really sounds like the AC adapter to me though.

                Dunno what people are talking about getting at the power supply, the power brick IS the power supply. The only thing on the internal connection is the routing for the battery charger and an electrical voltage split/step down. The Brick does all of the heavy lifting.

                Anyway, I suspect it's the brick, but if you're having a serious heat issue that means you're looking for a short. If there's a short on the board it'll be easy to spot/smell. Easiest way to test the brick is to put a load on it and see if it heats up.

                  Re: laptop/power problem

                  by power supply i think it was a refference to the small circuit board that the power cord plugs into, not sure if this one has it or not tho... or the plug socket or whatever, it hasnt done it since i posted last

                    That is what I was referring to. The circuit board that links the charging port to the battery (and computer components). I've tried fixing a few old laptops where that circuit wasn't working.

                      Re: laptop/power problem

                      Yeah, that's what the mnfg's refer to as the Power Board. Lot of bulk-brand mobo's don't have a separate power board, it's part of the mobo which is a shame because this is what breaks the most often for people, usually by physically damaging the pins in the connector.

                      Long-story short Power Boards are usually ~$25 parts and are generally pretty easy to replace if your laptop does indeed have one and it would be the next step if the AC adapter appears to be fine or you replace it and it doesn't solve the problem.

                        Re: laptop/power problem

                        ya im pretty sure its the battery, i was using it while laying on sofa, laptop on my chest, and the power light started blinking... i unplugged and replugged in the power from the back of the laptop, and about 15 seconds later the bottom of the battery on my chest heated up to a burning temp, as did the palm rest above the battery, immediately pulled battery out of laptop and threw it on the driveway (anyone ever see a laptop battery explode? im not risking my house burning down because of a laptop battery) why the driveway? cause thats the only safe place i could think of putting a possibly spontaneously combustible object that can melt metal
