Hi!
I could use some help.
I have a 645 G10 with some liquid damage around the bios chip.
After cleaning, the laptop does the same as in RHS93-s reply above.
""
1. F5 key LED lights up Orange
2. Power LED flashes White/Orange
3. Machine turns on and off like this a few times
4. Finally the F5 key LED turns off and the Power LED stays white
5. If I press power button in such condition I get 7 flashes on the CapsLock LED
6. Laptop reacts to the power button: if I press it long enough the machine turns off but then turns ON automatically and the cycle repeats
Under such condition I can see voltages on the motherboard going up: 3.3v, 5v are ON all the time. For a second or two I do get 1.8v for RAM and one of the CPU power stages (the high resistance one) goes up to 0.8v. Later these voltages go down and only 3.3v and 5v remain ON. ""
I think i have at least one or more components that disintagrated when cleaning could someone help my identfy what should be there and their values.
The first, red circle something is missing from there.
Second, yellow circle that component turned so gray i cant even tell if its a capacitor or a resistor.
Third, green circle i'm pretty sure nothing missing from there but the corrossion was the pretty bad there.
Could anyone please help?
