'They' say it can't be done, bah!

[RamarC]

I'm trying to upgrade a Toshiba Satellite 1415 laptop from a 1.8ghz Celeron-M to 2.2ghz Pentium 4-M. The laptop uses the i845-MZ chipset which supports both the Celeron and P4M. The Toshiba BIOS is revision 1.4 and the same BIOS is used by the Satellite 2415 which differs from my laptop only in its 2.0ghz P4M.

The laptop beeps continuously when POSTing with the 2.2-P4M. I've been told that the laptop is factory preconfigured for the type of processor and can't be changed. That sounds like a challenge to me. Does anyone have any info the mobo used in Toshiba 1415/2415?:evil:

Keep checking back on this post. When I get a chance I will see if I can get it to work.

Whenever I hear "It can't be done" it sounds like a challenge.

Got Digital Camera? Open up both laptops and take some high-res macro shots of the motherboards - specifically, anything that looks like it's a jumper bank.

If not, scope out anything that's different.

If all else fails, you might want to try a BIOS flash, but its kind of risky..

There are no jumpers on that board, or any Toshiba board for that matter, and he is already using the latest BIOS. I am currently waiting for a 1415 or 2415 to come into the shop so I can test with my 2.2GHz. Stay tuned.

Bumping back to the top. I had a 2410 come in, but the customer expedited the service I didn't have any time to try putting a different CPU in it.

I put a 2.2GHz into a 1415 and the unit emitted the same continuous beep tone as RamarC stated. I tried a few tricks I thought might work, but no change. Toshiba states that the 1415 is locked at 133MHz FSB for the CPU and the 2415 at 400MHz. The memory in the 1415 only runs at PC1600 (2x100MHz?, even with PC2100 installed) and the 2415 at PC2100 (2x133MHz). Also the Celerons run at 1.45V and the P4's at 1.3V (1.2V with speedstep). Now the motherboards have different part numbers for the 1415/2415 series, however the number indicates that they are practically identical. I will snap a shot of the clock generator of the 1415 and try to get one of a 2415 when one comes in. The clock generator is the ICS95805BGT.
