Hi DDR: This is one of the cases of posters assuming the obvious has been done before focusing on OS and Hardware issues. Guess we ask more questions next time.
Good your laptop survived and is running properly, also shows the value of not binning hardware until sure it is junk.

Hi Moddit,
well i would not call it that obvious the problem everyone faced on forums i saw was cooling and when the problem was the multiplier rmsclock solved i,in my case there was on the forum an elaborate theory why the multiplier tables were modified and so rmsclock could not call on them.
Also since doing the battery trick does reset all visible settings (clock and boot order for example) why would it not reset the setting that got the multiplier stuck.
About the survival thing,of course it survived,i can tell you are experienced and you know that all semi modern intel chips (and most others) will shut down strait up when they reach about 100 celcious.
I am not in any way recommending to boot without cooler but if you do,the overwhelming chances are nothing irreversible will happen,you must have been pretty unlucky with your technician or working on a really old chip because on modern cpu i have seen them dosens of times on youtube videos boot with inadequate cooling and just shut down instantly.Hi DDR, My last post was because new users follow threads like yours, do try to repair hardware and it is cheaper and safer to follow good practices.
My intention is not to show you up.Pls first think about why I wrote the way I did.
Reading handbooks, manuals and repair docs and BIOS settings are step one in a fault finding process, this is to avoid non necessary work, that often causes further damage which often does not show immediately.
Sure most processors or associated capacitors do not blow up immediately, caps do by the way if the protection is poor, as in many cheap power supply, or you get a mains surge.As you say most times the protection kicks in on CPU or GPU and you have a shutdown. Modern GPU is very damage sensitive. Pushing luck is at times expensive or even downright dangerous. Overtemping is known to cause micro damage every time it occurs.
An acquaintance does pretty good electronics repair work and is highly critical of some of the youtube videos on account of his experience, which is huge. He has to give a warranty on work, most of the youtube guys are only clickbaiting, most show the guys are working without static protection. Another risky practice which has cost me a board or two, over the years i have become more cautious.
The processor which self destructed was not old. It was expensive.
The Power supply unit was tested and found ok. The work is done with a shop protection against surge undervolt etc and a lead acid Battery buffer. All stuff only a serious shop can afford.And yes as you guessed, I do have repair training and experience in rather a lot of fields, computers started many years ago modding Atari ST..
