Greetings everyone!
I have a couple of issues with this model, which I have seen addressed here through the past years that I have been using it.
My first issue would be the innate lock of the HM70 southbridge, which shuts the computer down after exactly 30' if the CPU is detected not to be matching the HM70's "list". Through my research towards this issue's solution, I came across the ME's 30' shutdown restriction, which seems similar to what I am facing. I first got some hints of this from this post:
https://www.bios-mods.com/forum/Thread-U...processors, in case anyone is furtherly interested or facing the same issue. I haven't twinkled with MEcleaner yet, as I'm waiting for my flasher to arrive, but I have not many hopes for this issue to be solved, as I found out through a little more digging that ME's 30' restriction is irrelevant to HM70's 30' restriction. Once my flasher arrives I will attempt it either way, in case it miraculously decides to accepts my i5-3320M. Otherwise I will have to stick with the Pentium B960 that the machine came with.
This concludes the first issue and I'm writing this just in case anyone has any idea or advice that could potentially solve this issue.
The second issue concerns a BIOS mod or, if even possible, an upgrade. It regards the same machine, a Toshiba Satellite C850, which has been running on the latest official BIOS since the day it was purchased. This was approx. back in 2014, so, as expected, its battery has run out of juice by now... I recently bought an OEM new one, and, as if this machine is unwilling to accept anything that is fed to it, it isn't recognizing it. Instead, there is the battery LED blinking at a steady pace, even when the laptop is shut down. Also, the laptop will not be starting with this new battery plugged in.
I got around this issue by removing the battery, starting up the computer and then plugging it in, when it "recognizes" it and posts it at 100%. (I believe this is just the last-known condition of the old battery.)
This solves my problem short-term and allows me to flash a new BIOS as well, as the computer is tricked to think that it has a full battery, but I'd rather that I don't have to unplug and plug the battery every time I want to turn the computer on. (Also, if I remove the power cable, it will revert to the "LED blinking state", so it will shut down almost immediately.)
Through this post (
https://www.ifixit.com/Answers/View/5750...+installed) I found out that it is a BIOS issue yet again! The easiest solution is simply a BIOS update, yet, I happen to already be running on the latest official BIOS for this device... Here lies my question: Is there a mod, an unofficial BIOS version or even a revision anywhere?
I have upgraded this laptop's HDD to an SSD, adding a disk caddie in the process to host the spare HDD, its RAM from 4GB to 16GB (somehow that was accepted) and am looking forward to its CPU upgrade as well (I bought the i5 nearly a year ago)... With a new battery and all these upgrades, I see it running a couple of years more (at least until win10 are abandoned, or potentially even further).
Therefore, any help regarding the above two BIOS related issues will be much appreciated!
