Ask Sir Tony - an Electronics/Electrical Q & A thread

  • ^ would it be possible to bring the charger inside ace hardware and check if changing the power cable solves the problem? (Might be a stupid question, sorry). If not, how can I ask for the specific kind of power cable? Are there specific models or types of power cables? (Might be stupid questions again sorry) I don't really mind whether it looks presentable or not. I just want it to work lol. Btw, I'm using an asus g75 that's why Im finding it hard to look for a replacement (which really sucks). Thank you again for taking time to reply :)

  • Most laptop power adapters use this connector:

    Its proper name is IEC 60320-1 C5 connector. <click here for link>

    You can bring your adapter to the store, but I'm not sure if they'll allow you to test the cable before buying.

    Other laptop adapters use a two-prong connector like this:

    It can also be found in Ace hardware.

  • saan po nakakabili ng copper braid wire? 20, 22 awg.
    salamat po

    metromanila area.
  • ^ Try Raon.
  • Mga expert, tanong naman ilang aircon ang kaya ng 12awg electrical wire tig .7hp lang?
  • Gandang tanghali po, yung electric fan ko po nawalan ng power, pinalitan ko po yung capacitor (tama po ba) 1.5uF ng 2.0uF pero wala pa din, pinalitan ko power cord, wala pa din, ano pa po ba dapat ko i-check, ngayon lang po kasi nangyari ito.
  • @junt
    Baka may naputol na wire sa loob?
  • Mga expert, tanong naman ilang aircon ang kaya ng 12awg electrical wire tig .7hp lang?


    base sa AWG current rating table. pag #12, 34A ang kaya nya.

    theoretically:

    1 HP = 0.75KW
    .7HP ~= 500 watts

    P = IV
    500W = I (220V)
    I = 2.2A

    34A /3A = 10 na aircon kaya nya.



    pero syempre aircon yan, me inrush current yan. check mo yung manual nung aircon kung ilan ang inrush current nya. kung 5A ang inrush current nya,

    34A /5A = 6 aircon
  • mga boss tanung lang, may binigay sa akin na extension wire yung kasamahan ko na hapon, mau usb outlet sya, pwede kia gamitin sa pinas ito?

    get a multimeter (tester) check the coil winding of Stator Motor...
    If good... doon ka pa lang mag check ng capacitor, shafting bushing at iba pa....
    Take note... don't replace capacitors value# if not needed..
    If bad ... maybe thermal fuse is busted or rewind coil windings na..

    Salamat po sir =). Ang ikakabit po kasi 3 aircon lang ng .7HP sa ngayon at don lahat i tap sa AWG #12 may kanya kanyang breaker lang sya. Wala pa po kasi budget para malagyan ng sari sarili nilang 2 wires na linya.

  • tanong lang, normal ba sa cpu casing na magkaroon ng ground? kasi sa akin kahit naka unplug na sa outlet may ground pa din sya, nakakasira ba ito sa motherboard at iba pang parts? seasonic psu ko at bagong rma sya gumamit din ako ng corsair bagong bili ko ganon din may ground din.

    Kung may sariling ac plug ang monitor at hindi pa rin na unplug. Pwede pa rin magka ground yun casing ng pc.

    Solution. Unplug ang Monitor.

  • @circuit1234
    ganon pala iyon, ang ginawa ko na lang kasi nilagyan ko ng wire para sa ground nawala naman ang ground nya. thanks
  • tanong po about house wiring,

    ano po ang standard AWG size ng wire para sa electrical wiring? ok lang po ba mas malaki sa standard para bumaba ang kuryente?

    thanks
  • ok lang po ba mas malaki sa standard

    Yes.

    para bumaba ang kuryente

    I don't know where you got this idea.
  • tanong lang po...yung aircon po namin pag summer hindi lumalamig walang tumutulong tubig pero pagdating ng august hanggang january lumalamig at ang lakas tumulo ng tubig..2011 siya nabili
    carrier .5hp
  • Yung Lenovo Thinkpad Edge E530 ay nag-a-auto shutdown every 30 minutes. Pag ni-restart ay FAN ERROR ang nakasulat sa screen.
    Napalitan ko na ng bagong fan and heatsink pero ganun pa rin, nag-o-off automatically exactly every 30 minutes.
    Meron pa po kayang paraan para ma-repair ang auto shutdown neto?

    Eto po ang link from Lenovo site forum:

    Thanks for the help!
  • Have you monitored the temps to see if it's overheating?


    Maybe it's a power circuit issue? Just like PSUs shutting down due to overheating.
  • Good day mga sirs. Ask ko lang sana, accidentally naconnect ko isang appliance na 1400w sa extension na nakakabit sa UPS ko na 1000w. Ngayon ayaw na magcharge yung UPS, though nag oon pa rin pero as backup nalang. Any ideas kung ano pwede gawin? Thanks
  • Mga sir patanong lang po, yung microwave oven ko brandnew mga 5x ko lang nagamit. tapos gagamitin ko ulit ngayon, almost a year siguro natengga, biglang ayaw na uminit, normal naman yung tunog, may ilaw, umiikot,, pero walang init kahit konti. ano kaya pwedeng nasira? binuksan ko malinis naman loob eh, wala namang nakapasok na mabait..
  • ^caddtechgroup, buo pa ba yung fuse?
  • ^buo po lahat, parang gumagana siya, (pwera sa hindi umiinit) kumpleto ilaw eh pati yung spin nung plate.. check ko loob na fuse sa transformer and caps, buo naman din

  • yun computer po namin nag shushut down pag nag lalaro nang sims 3. Nilinis ko na yun cpu ganun parin,

    A10 5800k
    Yun psu is corsair 550

    Temp pag pag lalaro nang sims 3
    Hdd. 38-45
    Igpu 38

    Idle temp

    Hdd 38
    Igpu 10

    Anu po kaya pwede gawin sa pag trotrouble shoot btw wala pala dedicated hsf yun cpu anu po mura na magandang hsf for fm2 na socket? Thanks sa tulong
  • hello, anu po kaya sira ng ac adapter kapag low voltage? asus adapter 19v pero mga 10v lang ang output ng power?
    anu kaya possible na problem?
