Anda pemakai notebook toshiba satelite L510? Sering mengalami bluesreen? seolah olah windows-7 notebook anda ada masalah kerusakan sistem,atau notebook sering hang, atau gambar pecah pecah jika adaptor terpasang. Bukan yang awam mungkin masih menganalisa kemungkinan kerusakannya, coba install ulang windows-7, kadang berhasil kadang tidak sampai finish.

Awalnya perkiraan kerusakan notebook toshiba L510 pasti HDD,Memory, atau Fan cooler tidak berfungsi maksimal. Setelah dilakukan pengeceakan ternyata tidak ada perubahan. Coba otak atik sistem bios toshiba dengan mencoba melakukan perubahan setting dari AHCI ke IDE compatible, tetep saja tidak ada perubahan. Coba rubah setting core dari Dinamic ke low core, sama saja.



Tapi jika ketemu masalah yang sama pada notebook lain pasti tidak jauh beda. Jika notebook tersebut
pada mainboard atau motherboardnya menggunakan NEC Tokin entah itu OE907 atau OE128. Artinya nec tokin yang digunakan mulai bermasalah, Nec tokin ini letaknya dibawah soket prosesor.

Buat yang males mikir pasti cari jawaban mudah ganti motherboard toshiba dengan yang baru.
Tapi ingin kreatif coba deh perbaiki sendiri, tidak begitu sulit tapi yang penting mesti sabar dan hati hati.
  1. Siapkan kapasitor tantalum 330 sebanyak 4 buah.
  2. Lepas batere dari tempatnya.
  3. Lepas Hdd, dilanjutkan keyboard.
  4. Bongkar notebook toshiba L510, A300 atau L200 yang rusak.
  5. Cari posisi Nec Tokin OE907 dibawah soket prosesor.
  6. Lepaskan Nec Tokin dengan blower ( jika tidak punya coba disobek dengan solder biasa ) harus hati hati.
  7. Jika sudah terlepas, coba pasang kapasitor tantanlum 330 satu demi satu untuk mengganti nec tokin tadi.
  8.  ( jika banyak spare nec tokin, ganti nec tokin dengan yang baru ), jika tidak cara inipun maknyos mantep.
  9. Pastikan arah kutub positip negatipnya tidak salah. ( lihat pada gambar )
  10. Selesai, coba pasang dan lakukan pengetesan, booting awal yang langsung hang ( bluesreen ) kini tidak lagi.
  11. Ada baiknya Windowsnya di install baru agar lebih fresh.
Demikian tips dari skema-notebook.blogspot.com, cara memperbaiki toshiba yang sering hang, blue screen, gambar pecah pecah seperti vga rusak. Semoga bermanfaat.

ukur tegangan laptop

  On general principles, circuit size laptop sources are similar to the picture above.
  1.     TPS51020 ICs a 3v3 and 5V source.
  2.     IT8511 SIO.
  3.     A / D Dock In source adapter plugged in
  4.     VBAT is the battery source
  5.     AC_BAT is the power supply for the circuit, it can be obtained from the adapter or battery.

System Operation:
  1. Source level AC_BAT for IC source 3v3/5V (24 feet TPS51020)
  2. IC 5V 3v3/5V create (VREG5 feet 22 TPS51020) for SIO
  3. SIO get 3v3 from 5VAO line of IC 3v3/5V
  4. SIO Since pressure AC_IN (consider using Adapter or not)
  5. SIO ordered 3v3 and 5v source (EN1 and EN2)TPS51020 create 3v3 and 5v (one branch of the 3v3 or 5v will take back to Power feed SIO) remaining for the entire circuit.
  6. Signal TPS51020 Power Good (PWRGD) for SIO
  7. Button click 3v3 sources and wait press the power button.
  8. When pressing the power button click, SIO ordered secondary sources (or source) as: RAM native South, chip North, VGA chip source
  9. SIO continues to open source Vcore for the CPU completes the of source circuit size.

Test Flow circuit source:
  • Source AC_Bat to have and to foot powered IC 3v3/5v (the TPS51020). This source is open = 1 or 2 mosfet and usually drawn with the charging circuit. Refer to Battery charging circuit and open source AC_Bat.
  • TPS51020 must create and 5v (VREG5) grant for SIO.
  • SIO command to open the EN1 and EN2 of TPS51020 (if lost, we can try to apply to assume this command).
  • EN1 and EN2 must have 3v3 and 5v
  • 3v3 and 5v OK, PWRGD feet high
  • 3v3 and 5v ok, legs right sources 3v3
  • When you click the source, if other secondary sources are OK, the entire source will run. One of the secondary source "problem" circuit "protected" and disconnect all sources <- as excitement turned off.

Indication of Damage:
When the Acer Aspire One is turned on by pressing the power on, the screen does not display any blank alias. But the LED on the power button turns green. And there are no signs that the ACER ASPIRE ONE will be live and proceeds go to the windows.

Acer Aspire One cause of Death:
Death of Acer Aspire One is caused by the BIOS program is damaged or corrupted data occur in the Acer Aspire One BIOS of this. This is likely to occur as a result of a bug in the BIOS Acer Aspire One or the default from the factory.



repair acer aspire one dead

1. Prepare flasdisk maximum 2Gb, then format it with FAT partitions flasdisk. Just info, we use 2 Gb kingston pendrive brand black in color.


2. Download Acer Aspire One BIOS file, the following link : Here

3. Extract File zipnya, then extract the file again and copy the results of earlier extracted 2 files in it that is FLASHIT.EXE and ZG5IA32.FD to flasdisk directly without the folder / directory.

4. Plug in the USB port flasdisk left netbook Acer Aspire One

5. Plug Carger your Acer Aspire One netbook.

6. Press the Esc key and then hold down Fn and then press the power button once.
After about 15-30 seconds, release the Fn + Esc. Then the power button will be blinking

7. Press the power button again, then it will flasddisk lights blinking, a sign that the BIOS file in the flasdisk being accessed (Important..! Let some time because the process is running even though visible light does not turn on power.)

8. Wait a few moments, then the power light will stop blinking and then netbooks will restart by itself.

9. After restarting, the Acer Aspire One will live again normally.
(Bios Recovery Process Acer Aspire One is not more than 10 minutes).

Enjoy.
