Good afternoon or morning,
Returning, once after a 15 day in February 2018 trip and a second time after a 4 weeks trip up to end of April, I tried to start my Toshiba Satellite P870-11J.
it just booted (audible click) the CD drive and started the ventilator and then nothing : black screen and the ventilator re-starting, surging, humming, stopping and so on. Slight heating about where the power entry is and no audible harddisk activity.
Checking on Internet on similar problems (from my wife's computer) I found some comments indicating what amounts to "Black magic" for me : Unplug all connexions, including power, remove battery pack, press the on/off button for about 30'' to 1 minute, reconnect the power connexion and put the battery pack back and restart. I did that and had to do it many times including letting the computer rest - unconnected - for 12-24 hours. Finally it started again. (None of the comments ever explained WHY this incident occurs).
Yesterday, i had a very lengthy and heavy update upload from Windows when closing the computer. On start-up : dead again. "Black magic" again + 1 night unconnected and it started again.
Maybe important note : I usually use the "sleep" mode when stopping using the computer, booting rather rarely. Before yesterday I did stop completely and booted completely even after the two occurrences mentionned above, without problems those times.
Of course, I know, I know, my Toshiba is probably considered as very obsolete, but, appart from the incidents describes above, it works well and has no other problems. By the way, I am running Windows 7 Premium Home Edition, 6.1, SP 1. I have 565 Go free space on the harddisk and I defrag regularly and clean up regularly with CClean.
My question :
Is there rational, scientific explanation to this kind of problem and, above all, a less "Black magic" way of resolving, even better, preventing it ... of course outside the purchase of a new computer !
Many thanks for your advice !
