Topic: Lenovo G500 does not boot without batteries
Hello. Actually, a question in a subject title. G500 (Pentium G2020), slightly - instead of regular HDD it is installed SSD OCZ 460A, it is added the storage unit 8Gb (and one-in-one selected pressure as at factory 4Gb the unit), total 12Gb RAM, the matrix is replaced on IPS right after purchases. After all changes fulfilled without remarks 2-3 years (precisely I do not remember how many), never completely understood, since the construction is that that access to system and to all principal components is given after untwisting of two screws and removal of a back cover. Recently ceased to start confidently. From time to time switching-on comes to an end on a logo of Lenovo and further happens nothing, to buttons does not react, in BIOS does not enter. After the notebook starts batteries BIOS (each time it is necessary to remove a back cover) absolutely normally. Special regularities it is not revealed, besides, that the first similar glitch happened after long inactivity of a notebook, but here today again happened, last time thus turned on about 2-3 days ago. On a software - Windows 10 x64 LTSB pure, not the assembly by_Vasyan, Office, well and standard and . I can not understand where to catch a glitch. The first thought was about SSD - but the firm utility shows the green status and health of 95 %.
