Re: Dell 13 7359 not post, only led blink
Bios dumps are from badcaps forum. From this thread, first post: [URL="https://www.badcaps.net/forum/showthread.php?t=90708&highlight=cottonwood+mlk+mb+14275-1"]https://www.badcaps.net/forum/showthread.php?t=90708&highlight=cottonwood+mlk+mb+14275-1[/URL]
Fan is spinning fast, at same speed all time. After some time laptop turns off.
Exactly as before flashing bios.

Hi all,
I have here this laptop. When power button is pressed LED is blinking 2 amber and 5 white - problem with memory. And fan is running at full speed, CPU is hot little bit. I tried 3 different modules of DDR3L memory but problem persist. I tried 4gb and 8gb RAM. Slot looks fine.
1.xxV voltage on ram is present. No water damage.

Macbook A1398 2013 820-3787-A not charging
Hi all,
I have problem with this macbook. Laptop works fine on the magsafe charger but not working from battery and not charging. There is no battery sign in macOS, in system info: battery cycle count 0, charging no, battery capacity 0.
Battery is new, old was "bloated" ..
On board I have 11.5V when Magsafe connector is disconnected. Now I don't know if my new battery is bad or I have same problem on board... how to check it please? maybe check sda, scl with oscilloscope?
And I try SMC reset, pram,nvram and nothing help.
Led on magsafe connector... -
