Da Gestione periferiche non mi vengono visti quindi non c'è problema software...

Come posso avere la certezza che il problema è del circuitino e non della connessione elettrica? E' molto strano che sia il touchpad ad avere problemi. Presumo esista un metodo per la verifica elettrica del circuitino.

Prima del disassemblaggio ogni tanto non funzionava, ma il tastino s'illuminava. Attendo maggiori info.

Ho trovato la procedura di diagnostica Acer in lingua inglese:

"Touchpad Check

If the touchpad doesn’t work, do the following procedures in sequence to

correct the problem. Do not replace a non-defective FRU:

1. After rebooting, run the Tracking Pad PS2 Mode Driver. For example Syn touch driver.

2. Run the utility with the PS/2 mouse functi on and check if the mouse is working.

3. If the PS/2 mouse does not work, then click if the main board to switch board FPC is connected properly.

4.If the mainboard to switch board FPC is connected correctly, then check if the FFC on the touchpad board

is connected properly.

5.If the FFC on the touchpad board is connected correctly, check if LS851 JP1 Pin6 = 5V are pules. If yes,

then replace switch board. If not, then go to the next step.

6. Replace the touchpad board.

7. If the touchpad still does not work, then replace the FPC on touchpad board.

After you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer movement

will occur when a slight, steady pressure is applied to the touchpad pointer. This symptom is not a hardware

problem. No actions are necessary to be taken if the pointer movement stops in a short period of time."

Tom1 o Meg, potete supervisionare alla procedura di diagnostica?
