Boot loop x 250

2018-09-24, 0:09 AM

My laptop seems to start for 2 seconds maybe, with fan, keyboard lights, power light coming on, then shuts down and repeats. To stop the loop I have to push the power button about 10 or 11 times and hold it. Sometimes if I take out the external battery, let it sit for a while, it works again normally. Any ideas?

Solved! See the solution

Problem seems to be solved, although I'm not sure what did it.

1) Opened the back, cleaned contacts for memory, checked contacts for battery and HD.

2) Cleared CMOS with internal battery detached

3) What surprised me was that when opening the back, most of the screws were quite loose, perhaps enough to comprimise  the integrity of the structure of the case and affect contacts of memory or something else when picking it up?

A HD scn and Lenovo system scan came out totally clean afterwards
