Should I update the bios ? (yes, but do it with your own risk)
« on: November 09, 2019, 03:41:37 am »
I have Toshiba L745 with part no : PSK12L-02U00G
This laptop sometimes suddenly shutdown and showed battery lamp indicator & power indicator blinking. (If this happen looks like hardisk is broken, need bios update, ram is broken, laptop automatically shutdown in a way to protect from data loss due electric shock)
In few years ago I fixed that by buying new HDD.

And now that happened again. I'm buying a new SSD adata su650 120gb, but it wont fixed that, my laptop still randomly shutdown (when tried to install windows 10 randomly shutdown) :'(
I tried any possibilities but nothing was fixed and I leave my laptop without electricity for one day.

Next day no idea my laptop is no more shutdown randomly anymore  ??? For now I can run windows 10.

My bios ver 1.6

Thats link for bios ver 2.6 support laptop toshiba L745 with first part no : PSK12*

I run that and see this

This BIOS is aplicable to the following models :

-satellite L410/L745 models having part numbers beginning with "PSK0YU"
-satellite L745 models having part numbers beginning with "PSK0YM"
-satellite L745 models having part numbers beginning with "PSK0YP"
-satellite L745 models having part numbers beginning with "PSK12M"
-satellite L745 models having part numbers beginning with "PSK12P"
-satellite L745 models having part numbers beginning with "PSK12U"
-satellite pro L740/L770 models having part numbers beginning with "PSK0ZU"

for purposes of this document, the term satellite L745 is used to generically refer to all of the models listed above

What should I do update it or not ? I can't find anymore bios update in google with same part number (PSK12L)  :-\

You'll not get anyone to answer that question for you my friend .. you're asking people to comment on something that could potentially brick your system.

I'm afraid that risk/choice is yours and yours alone.

As an aside, to what the chief said...

Around the turn of the century, I used to buy bricked Cisco 678 ADSL routers on eBay, for pennies - restore the CBOS (through a CLI backdoor) - and resell them for a dandy profit. I bought these bricked routers for $20.00-ish USD, restored CBOS, and resold them for $200.00-ish USD.

I had an unlimited supply of bricked Cisco routers on eBay because (inexperienced) users would try to do a flash update and brick them.

Here's a POC, if you're interested:  https://is.gd/MIt79X

Caveat emptor   ;)

I am late to the party.

I was thinking about updating the BIOS and did not do it. I love peace and silence.
Correct me if I am wrong but it might be a good idea to stay with an old BIOS if it still works and get some nice linux-firmware updates. Use a secure browser and enjoy your life.

All the best!

Sure if all your hardware is working properly, there is usually no reason to risk a failed BIOS update bricking your system.

There are the occasional instances where a BIOS update might be security related, in which case you **might** want to consider it anyway, but generally if everything works, leave well alone.
