Зарегистрирован: 17 май 2013 21:41 Сообщения: 7 Город: Санкт-петербург	Aser aspire 5542g-303g25mi. Платформа WISTRON : 09230-1, JV50-TR MB, 48.4FN01.011. При нажатии кнопки включения загорается светодиод, запускается кулер и на этом заканчиваются его потуги включится. Экран не загорается ни на секунду. Радиатор постепенно нагревается и кулер крутится быстрее. Решил для диагностики приобрести POST карту PTi8: выдает код ошибки 00(control to int 19 boot loader), но сомневаюсь что он верен так как если на эту карту подать 3.3V и GND то она выдаст тоже самое. Я полагаю проблема все же в GPU, но как можнот в этом удостоверится? С момента покупки иногда выключался дисплей, снова включался с сообщением: « Видеодрайвер перестал отвечать и был успешно восстановлен». Но для обмена поймать его не удавалось. Так он и прожил 3 года. На ночь отправил его в гибернацию. Утром он уже не подавал признаков жизни.

Ноут умер еще в октябре. Уже давно куплен новый. Мне интересен сам процесс выявления неисправности тем более если бы вылетел какойнибудь стабилизатор я бы вполне мог его заменить. А по поводу сервисов). У меня работает друг в одном таком. Принесли ноут не выключался оказалось перестал заряжаться БП заменили все работает. Звонят клиенту: Мы заменили вам БП, но у вас тут еще материнка глючит, можем заменить на новую 3000р. или починить эту 2000р. Клиент согласился на починку. Они капнули флюса на материнку высушили и отдали клиенту рабочий ноут взяв лишние 2000р.

Здравствуйте!
Не могу диагностировать ноутбук eMachines D640G-P322G25Mis. Нет сигнала на дисплей.

1. Ноутбук включается и внешне всё отлично. Кулер крутится.
2. HDD тоже крутится, но загрузки ОСи никакой я не заметил. Индикации нагрузки на диск тоже нет, но на сколько я помню должна быть! (флешку тоже пихал, ничего не понял, 5V есть а обращений нет).
3. Отключается при удержании на < 2 секунды.

Самое странное, что при подключении через VGA внешний монитор не реагирует на подключение (продолжает сообщать о не подключенном кабеле). К сравнению, если подключить к выключенному но рабочему ноутбуку подключение сразу обнаружено.

Это уже второй по симптомам похожий случай поломки. В первый раз всё обошлось простой заменой батарейки 3V, как в этом случае —

После чего он проработал ещё целый месяц и «потух». Батарейка уже не причина неисправности. Планка ОЗУ рабочая проверил.
Прошло больше 2-x лет, и решил я заняться им. Купил у китайцев диагностическую карту PTi-8 вот она

Ну сел диагностировать, вставил в порт WiFi. Но он показал только один код 00. Наличие 3.3V в остальных 5 и 12 нули. Тест сигналов RST, IRDY, FRAME все Invalid. Кажется всё…
Далее решил подпаяться по интерфейсу LPС получил более полный, но думаю бесполезный набор пост кодов —

1. 00 Control to Int 19 boot loader (ранее уже упомянутый)
2. 01 Disable NMI
3. 03 Soft reset power-on
4. 18 Color (EGA) mode set ok (6845)
5. 22 Memory Read/Write
6. 25 Read input port of 9042 chip clear password
7. 28 Set video mode
8. 32 Alternate display netrace check
9. 35 Initialize BIOS ROM data area
10. 36 и 37 Power-on message display (кажется описание одинаково, но 36 100% соответствует)
11. 38 Initialize BUS tupes
12. 2A Initialize BUS
13. 0B Initialize before keyboard balch
14. 0D Verify batch command
15. 4D Save memory size
16. 2E Display memory Read/Write test if no EGA/VGA
17. 2F Что-то похожее с 4 пунктом (никаких фейлов эрроров и прочего)
18. 4F Sequential and random memory test
19. C7 CMOS Shutdown register test
20. Final code: 00 Постоянные циклические значения кодов строкой ниже — при отсутствии RAM в разъёмах.
Кажется это всё, что мне удалось найти
Если нужны замеры мультиметром, было бы не плохо показать к примеру на этих фото где мерять —

BIOS Post Procedures — For BIOS’s of Feb 1991:

NMI Disable	NMI interrupt line to the CPU is disabled by setting bit 7 I?O port 70h (CMOS)
Power On Delay	Once the keyboard controller gets power, it sets the hard and soft reset bits. Check the keyboard controller or clock generator if a failure occurs
Initialize Chipsets	Check the BIOS, CLOCK and chipsets
Reset Determination	The BIOS reads the bits in the keyboard controller to see if a hard or soft reset is required (a soft reset will not test memory above 64K). Failure could be the BIOS or keyboard controller
ROM BIOS Checksum	The BIOS performs a checksum on itself and adds a preset factory value that should make it equal to 00. If a failure occurs, check the BIOS chips
Keyboard Test	A command is sent to the 8042 keyboard controller which performs a test and sets a buffer space for commands. After the buffer is defined the BIOS sends a command byte, writes data to the buffer, checks the high order bits of the internal keyboard controller and issues a No Operation (NOP) command
CMOS	Shutdown byte in CMOS RAM offset 0F is tested, the BIOS checksum calculated and diagnostic byte 0E updated before the CMOS RAM area is initialized and updated for date and time. Check the RTC and CMOS chip or battery if a failure occurs
DMA (8237) and PIC (8259) Disable	The DMA and Programmable Interrupt Controller are disabled before the POST proceeds and further. Check the 8237 or 8259 chips if a failure occurs
Video Disable	The video controller is disabled and port B initialized. Check the video adapter if a failure occurs
Chipset Initialized and Memory Detected	Memory addressed in 64K blocks. Failure would be in the chipset. If all memory is not seen, failure could be in a chip in the block after the last one seen
PIT Test	The timing functions of the 8254 Programmable Interrupt Timer are tested. The PIT and RTC chips normally cause errors here
Memory Refresh	PIT’s ability to refresh memory is tested. If an XT, DMA controller #1 handles this. Failure is normally the PIT (8254) in AT’s or the 8237, DMA #1, in XT’s
Address Line	Test the address lines in the first 64K of RAM. If a failure occurs, an address line may be the problem
Base 64K	Data patterns are written to the first 64K of RAM, unless there is a bad RAM chip in which case you will get a failure
Chipset Initialization	The PIT, PIC and DMA controllers are initialized
Set Interrupt Table	Interrupt vector table used by PIC is installed in low memory, the first 2K
8042 Keyboard Controller Check	The BIOS reads the buffer area in the keyboard controller I/O port 60. Failure here is normally the keyboard controller
Video Tests	The type of video adapter is checked for, then a series of tests are performed on the adapter and monitor
BIOS Data Area	The vector table is checked for proper operation and video memory verified before protected mode tests are entered into. This is done so that any errors found are displayed on the monitor
Protected Mode Tests	Perform reads and writes to all memory locations below 1MB. Failure at this point indicate a bad RAM chip, the 8042 Keyboard Controller or a data line
DMA Chips	The DMA registers are tested using a data pattern
Final Initialization	these differ with each version. Typically, the floppy and hard drives are tested and initialized and a check is made for serial and parallel devices. The information gathered is then compared against the contents of the CMOS and you will see the results of any failures on the monitor
BOOT	The BIOS hands over control to the Int 19 bootloader. This is where you would see error messages such as non-system disk

I got a problem with a PC who won’t even start, so i installed a post card and the message it gave me was «00 : Copying of code to specific area done. Going to give control to INT-19 boot loader». The fans and CD-drive all seems to work when I power the PC on but nothing shows on screen and the led for HD activity doesn’t show anything (might be just the connexion to the led).

I got 2 of these PC, 1 working the other not so i went and remove, 1 by 1, all the pieces of the not working one and put them in the working 1 to see wich one was defect but all (CPU, HD, RAM, Power Suply) just work fine when they are in the working PC.
We did change the motherboard once with no result, so what are the odds of having the same problem on 2 different motherboard ?

So I was wondering if any of you got the same problem, or if you have any idea on what the next logical step should be. If some part of the problem doesn’t seem clear juste ask, I’ll gladly answer.

Thx
