Task;

  1. Replacing the faulty LCD panel. – successful
  2. Repair windows genuine problem – successful
  3. Repair windows error regarding starup hang on starting windows page & hangs on start up disk check – successful

For task 3;

  • After checking we find that the startup diskcheck checking the D: drive, so we disable thru registry and thats solved the issues;
    • how to disable check disk at startup
      • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
      • disable automatic disk checking at Windows startup through registry, go to the following registry key:In the right hand pane, double click BootExecute. The default value of the key is autocheck autochk *
      • * means every drive is checked for consistency. Just add /K:D at the end before *. /K switch will disable autocheck on D: drive at Windows startup. So the final value should look like this: autocheck autochk /k:D*

Masalah window dan skrin berkelip-kelip. Setelah dibuat pemeriksaan dan diuji kami dapati;

  • Windows gagal untuk diloading;
    • Repair menggunakan cd installer ( under iklik warranty)
  • Butang key pada keyboard tercabut;
    • Butang ‘esc’ tercabut dan dipasang semula.
  • Skrin berkelip-kelip;
    • LCD inverter ada kesan ‘burn’ hangus terbakar – punca utama kenapa skrin berkelip.
    • Webcam juga bermasalah akibat dari inverter ini – webcam disambungkan melalui inverter ini.
    • Sekiranya digunakan terus inverter yang terbakar ini,boleh mengakibatkan kerosakan yang lebih teruk kepada LCD yang berkesudahan LCD jd rosak dan tidak dapat diselamatkan lagi ( alamatnya beli yg lain).
      • Kami test mengunakan inverter dan lcd yang OK;
        • Tiada lagi skrin berkelip-kelip, skrin ok.
        • Webcam boleh digunakan.
      • Kami tukarkan inverter tapi mengunakan LCD yang sama;
        • Skrin berkelip-kelip pada permulaan dan kedengaran bunyi seperti ada electrical shortage ( Zheezzzzee…) pada penjuru bawah sebelah kiri.
        • Bila posisi LCD digerakkan, bunyi hilang dan skrin jadi stabil. …akan diuji sehingga sehingga lewat malam nie ( 23.05.. )
