Cara Mengukur Sumber Tagangan Motherboard 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.

How To Recover Acer Aspire One Death

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.

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.

Mengenal Elco ( Capasitor ) Atau Kondensator

Capasitor/Elco atau nama lainnya adalah kondensator. Adalah komponen yang terdiri dari 2 pelat logam yang dipisahkan dengan isolator. Isolator ini menunjukkan nama dari kapasitor tersebut. Ukuran kapasitor adalah Farad.

1 Farad (F) = 1.000.000 mikro Farad (F)
1 mikro Farad (F) = 1.000 nano Farad (nF)
1 nano Farad (nF) = 1.000 piko Farad (pF)

Sifat kapasitor adalah dapat menerima arus listrik dan menyimpannya dalam waktu yang relatif.
Jenis ada beberapa macam antara lain :

a. Kondensator Elektrolit / ELCO (kondensator yang memiliki polaritas, kaki + dan kaki -)
b. Kondensator Keramik
c. Kondensator Mylar
d. Kondensator Mika
e. Kondensator Kertas

Penggunaan kapasitor dalam rangkaian :
• Sebagai perata arus
• Sebagai penyimpan arus listrik


Simbol Kondensator dalam Rangkaian adalah "C" dan simbol gambarnya adalah :


Cara Membaca Elco

Misalnya dibadan ELCO tertera tulisan 10uF/16v berarti ELCO tersebut memiliki ukuran 10 mikro farad dan tegangan kerjanya maksimal 16v. Jika tegangan yang diberikan lebih besar dari tegangan kerja maka ELCO akan rusak. Sisi ELCO yang terdapat tanda panah menunjukkan kaki disisi tersebut adalah kaki negatif.

Cara Membaca Kapasitor Keramik / Mika / Mylar

Misalnya di badan kapasitor tersebut tertera tulisan 103 artinya :
• Angka I : melambangkan angka
• Angka II : melambangkan angka
• Angka III : melambangkan jumlah nol & ukurannya dalam piko Farad.
Jadi nilai kapasitor tersebut adalah 10.000 pF = 10 nF = 0,01uF.

Mengukur Elco Dengan Multitester
1. Putar batas ukur pada Ohmmeter X1 / X10 untuk elco yang ukurannya besar dan X100 / X1K untuk elco yang ukurannya kecil.
2. Hubungkan probe ke masing-masing kaki ELCO (bolak balik sama saja)
3. Lihat penunjukan jarum pada papan skala.

Kesimpulan Hasil Pengukuran

• Jarum menunjuk angka & kembali ke tempat semula : elco baik
• Jarum menunjuk angka & tidak kembali ke tempat semula : elco bocor
• Jarum tidak bergerak sama sekali : elco putus
• Jarum menunjuk angka nol : elco short

Mengukur Kapasitor Non Polar Dengan Multitester
1. Putar batas ukur pada Ohmmeter X1K / X10K
2. Hubungkan probe ke masing-masing kaki kapasitor (bolak balik sama saja)
3. Lihat penunjukan jarum pada papan skala.


Kesimpulan Hasil Pengukuran :
1. Jarum menunjuk angka kemudian & ke tempat semula : kapasitor baik
2. Jarum menunjuk angka tdk kembali ke tempat semula : kapasitor bocor
3. Jarum tidak bergerak : kapasitor putus
4. Jarum menunjuk angka nol : kapasitor short
