У меня ноутбук на ремонт после перенапряжения. ущерб основной преобразователь 1.8 для TPS51116, после замены короткого нет. Ноутбук должным образом реагировать на ON / OFF, однако, ничего не отображается на матрице и внешний VGA-выход. После включения вентилятор некоторое время, затем останавливается и начинает снова. Я измерил напряжение на основных преобразователей 5 В 3,3 В 1,8 В и 1,25 В. Ноутбук батареи начинает, но потом не включается вентилятор только на некоторое время. Может ли это быть поврежденным NCB управления. Извините за мой русский С уважением Northwind Платформа: Quanta BD3A |

Don't use google translate as poland->russian. Use poland -> english. Find platform name on PCB. |

Platform is Quanta BD3A. I don't hear any post codes in speakers. |

Post codes is not beep by speakers. You need the post card in mini-PCI slot to look post codes or check it by oscilliscope. Try another CPU or heat north bridge by heat gun 300 C degree 10-15 sec. |

At 1.8 V Vsus resistance 37 OHM's. Unfortunately I have no other processor. That was my main suspect memory or processor. Laptop acted earlier against overvoltage. |

What can I replace the CPU processor TMDTL62HAX5DM??? |

I havn't BD3A schematics - BD3G olny. BD3G have LPC on mni-PCI CN30 only. BD3A has one or two mini-PCI slots? Try install post card in another slot. May be this platform hasn't LPC on any mini-PCI. Give the list of chipsets used in BD3A: south, north briges, video chip, multicontroller (KBC). I take the BD3A schematics - the same as BD3G LPC. Put POST card in CN30 only and check post codes (if present) CLK and Reset. |

Here is a link: viewtopic.php?f=250&t=1393&p=21028&hilit=*bd3a*#p21028. I have far too few points. I'dont heat north bridge. I think north bridge is OK. Laptop worked against short circuit. |

BIOS battery disconnected overnight. Laptop works. Damaged was also one of the memory chips. I wonder, however, the CPU fan, often regulated by turnover, even when you save energy and reduce the clock speed to 800 MHz. What is the efficiency of the inverter should be 1.8 Vsus? |

The inverter must have the appropriate power input and give output. The efficiency ratio is: output power to input power. I wonder if that system I could rebuild has the same efficiency after repair. What is important is that the laptop so much when it gets very busy a lot of energy. Power supply for this laptop is 3.2 A. When the inverter efficiency will be less, when take more current from the input. It could be reset, or work not being controlled. |

Now I'm at work. Not yet checked the charge, wifi, modem. How do I get home I will know. This irritates me a fan. Change the thermal paste and see. |

Finally, I had the time. I checked the rest of the peripherals. So: does not work ISL6251 charger or the battery system is not operational. There is only one memory slot (memory Lookin 'good). After replacing the paste on the CPU, the fan is stable. A tip me how to check the charger. Laptop properly reacts to release the AC adapter. |

Battery present at windows? Install another battery if possible. Connect the adapter and battery and check voltages on both side of PL12. If voltages is the same, battery not charging. |

The owner said that the laptop battery is not booting for a long time. I always had a 4%, 3%. Withstand 3 min. The system indicates that the loads. But the percentage of battery capacity is not growing. I do not have a second battery. What amazes me is that only one DDR memory slot works. Is the processor can be damaged any of the ports. Both are in working memory orginal. How do I install both the laptop will not wake up. |

Check the voltages. About memory - may be processor, may be slot. Replace processor or use one slot only - it's cheapest way. |

I am when it comes to repairing laptops amateur. I managed to fix 4 pcs laptops at four approaches. Repair laptop at her friend. I have a wife as I do not care;) So I guess I'll give it a rest, because it verifies only charger I have ISL system. And the voltage 1.8 VSUS the memory slot. |

The CPU is damaged. I replaced it and it's fine. The battery is defective. Once plugged in the charger voltage increases to 11.56 V. The nominal voltage of 10.8 V |
