#1 Lenovo v330-14ikb; DLME1/V2 LA-F481P; wyświetla się logo Lenovo i stoi

Dzień dobry!
Laptop Lenovo v330-14IKB po przyciśnięciu przycisku power, startuje, włącza
się ekran, pokazuje się logo Lenovo i nie idzie dalej.
Jestem w stanie zapalić caps locka(szybko przyciskając podczas
uruchamiania) ale już się nie da wyłączyć - po chwili barak reakcji na
klawisze, nie da się wejść do biosu.
Wyłączony laptop pobiera 20mA, widocznie ciepły układ ethernetu.

Przycisk "NOVO" włącza kompa identycznie jak power.
Bateria biosu była odłączana. Dysk odpięty, ram raczej ok.

Pomiary na zdjęciu poniżej (na żółto napięcia przy wyłączonym laptopie, na czerwono przy włączonym):

Proszę Was o wskazanie kierunku.

Paweł

Try a USB keyboard if you can access the bios.

If you are satisfied with my help, look here:

This chip is very likely damaged.
Remove it from the board and remeasure the power consumption of the board, when the machine is turned off. Also check if the machine still freeze on the Lenovo logo with this chip removed.

I find out the connection to AVD33 for this chip and made a brake..
There is no short to GND on any pin of this chip.
Drain is now 10mA as off but same situation after power on with Lenovo logo.

Nie rozumiem, dlaczego robisz coś po swojemu, zamiast stosować się ściśle do zaleceń? W ten sposób daleko nie zajdziesz. Uszkodzony układ LAN - nawet pozbawiony zasilania 3,3V - może blokować PCH w procesorze na liniach PCIE. Dlatego kol. matic zalecił wylutowanie kontrolera, a nie tylko odcięcie jego linii zasilania.

I finally removed the LAN chip, Unfortunately nothing changed..
