CPU Upgrade for Toshiba Satellite L550 & L555 with HM55 chipset

[m1co]

Greetings guys!

Im so desperate, i have tried running i3 370M and i5 560M on this motherboard, wasted a lot of money on these but bios does not support either.

MOBO: Toshiba NTWAA
Chipset: HM55
Direct BIOS download link: http://support1.toshiba-tro.de/tedd-file...145054.zip

Bios version 2.2, this is the last updated one on Toshibas page.

Anyone please tell me what to do?

Or maybe if it is possible to unlock a cpu support in bios, i would be very grateful, even willing to pay you!

Your laptop is based on LA-5322P motherboard. It has BIOS without support for stepping K0.
So you can use only these CPUs with stepping C2:

1. Celeron P4500 (SLBNL)
   
2. Pentium P6000 (SLBWB)
   
3. i3-330M (SLBMD)
   
4. i3-350M (SLBPK)
   
5. i5-430M (SLBPN)
   
6. i5-520M (SLBNB)
   
7. i5-540M (SLBPG)
   
8. i7-620M (SLBPD)

It can't be changed by adding microcode.

How can I make the BIOS Update? with Winphlash?
My accu is dead so the original tool dont let me...

[DeathBringer]

No, Winphlash isn't not compatible. It's Phoenix SecureCore Tiano BIOS.
Try to edit BIOSCheck.ini and set BatteryCap to zero.

It refuses to start, although the chipset supports these processors. Processors tested working!!! A whitelist is also installed on network cards, for example, on AC-7260. Please help if possible!
