  • well for power supplies all electronics will follow the usual +/- 10% of the actual rate.

    may drop voltage at peak voltage naman yan, lahat ng electronics meron dapat tolerance with voltage spike and voltage droop.

    so a battery that is 10.8 and 11v will make no difference at all. Although since mababa yung amperage nung nabili nya, mas mababa din yung uptime ng laptop nya,

  • @ awakeruze mas tama nga po kayo sr ... may point din c sr polka ..... :)
  • salamat sa informative answers mga kaTCP
  • Hello po.. Meron po akong HD na hindi na detected at out of warranty na rin, naisip ko lang po na mag wowork siya ulit if kung papalitan ko yung PCB Board niya na same model din at working kahit low capacity nung HD. Pede po ba yun? Nag try na po kasi ako ng ibang model na PCB Board nag work naman siya at na detect pero may issue na slow at naging 3GB yung capacity which is 500gb siya. Sayang po kasi..
  • Why don't you try a PCB from the same model?
  • ^ok sir salamat, pero sa tingin nyo sir mag wowork out siya with same model.
  • If it works, you need to do a low-level format (zero-fill) of the entire hard drive before you even use it. Why?

    Each hard drive has defects (bad sectors) during manufacture. These bad sectors are identified, recorded in the drive's NVRAM (non-volatile RAM, like flash memory), and swapped with spare sectors.

    When you transplant the controller board from one drive to another, the defect list comes with it. And since it's a different drive, the contents of the old defect list are invalid, which means you have to do a low-level format (also known as a zero-fill operation) to find the bad sectors.

    A low-level format requires specialized software, usually manufacturer-specific; using the format command during OS installation is not a low-level format.
  • @charlzman2k7,

    Nag post din ako dito about s ganyang problem ko sa hdd ko. Nagawan ko din ng paraan nag search lang ako sa google at watch sa youtube.

    Una need mo icheck kung talaga PCB nga ba ung sira ng hdd mo. Dapat pag kinabit mo sa PC ung hdd mapapansin mo na walang power or hindi umiikot. Kung wala power ung hdd at di umiikot. Try ko check ung pcb. Check mo kung may tvs diode na sunog. 2 ung tvs diode na ung 1 5v at 1 12v. Meron sa youtube kung paano icheck kung ok o sira ung tvs diode ng hdd.

    Ung sa problem ko naman ang ginawa ko nag hanap ako dito sa tipidpc ng hdd na good condition na same specs ng hdd ko. Kung gusto mo un itry hanap ka din same specs ng hdd mo ito ung mga dapat mo icheck dapat same sila.

    Pag may nabili ka na na same specs ng hdd mo need mo iswap ung ROM chip sa pcbng hdd mo sa pcb ng hdd na nabili mo. Ung kasi need para ma detect ung data sa hdd mo na sira ung pcb.
  • @rainier

    Maraming salamat po sa tip sir.

    Ok lang ba sir na kahit low capacity nung HDD na mabibili ko basta same spec ng:

    Ang nangyari kasi sir na stock lang siya ng ilang months tapos nung gagamitin ko na hind na siya madetect as in, pero hindi ko pa na obserbahan kung umiikot at may power. Thank you ulit sir

    Try removing all drives (CD, HDD).

    It could also be BIOS corruption or bad RAM.
  • @ sir awakeruze na try k na rin alisin cd at hdd ganun parin d mapsok bios nya..
    Pero pag ung ram nya tinangal ko walang display...
  • Pero pag ung ram nya tinangal ko walang display...

    Of course that's gonna happen.

    If would have been nice if you have spare RAM to test.
  • @ sir awakeruze ganun ba sir... Try ko po ibang ram bka gumana pa matagal kasi naka stock ito...pano ba malalaman pag board ang sira sir
  • .pano ba malalaman pag board ang sira sir

    By elimination.

    Once you're 100% sure that every other component of the laptop is OK (RAM, HDD, keyboard, AC adapter, processor), and the board is the only remaining part that you can't test, you can conclude that the board is defective.
  • Thank you sir @awakeruze...
  • Good morning mga, sir. :)

    Nagii-stutter ung pc ko madalas kapag naglalaro ako ng games, tsaka minsan kahit internet browsing at simpleng click lang ng icons.

    Chineck ko po sa DPC Latency Checker, ndi po baba ng 2000+ ung value at maximum ay 4500+. Pati sa LatencyMon po chineck ko, tatlo ang lumalabas na may problema. Naging consistent ung hal.dll, ataport.sys tsaka ung usbport.sys.

    Paano ko po mafix to? TIA! :)
  • Ask ko lng if repairable pb if dina nsasave ung date and time sa cmos

    Nagpalit ndn ako batt pero gnun pdn

    Need to set date and time 2wing bagong boot
  • just a silly question lang paps; save settings ka ba before exiting BIOS?
  • Mga sir bago lang po ako sa computer parts gusto ko lang po iupgrade yung ram and processor ng motherboard ko kaso hindi ko alam kung compatible siya dyan eto po yung model nung motherboard "H-I41-uATX (Eton/EtonL)" 2GB lang kasi ram ko ngayon balak ko po gawin 4gb ram. Or bumili na lang po ako ng bagong motherboard and processor? pero mas maganda kung mauupgrade ko yan kasi mas sobrang mura parts. salamat po sa makaktulong..
  • save settings ka ba before exiting BIOS?

    Dipende. If changes were made and you'd like to save it, then yes. If unsure, don't save. Ask first, di baleng magtanong muna kesa no boot. :)
  • i was asking gancho sir :)
