These Processors will work with your system:
Intel Core 2 Duo processors:
2.20-GHz processor (4-MB L2 cache, 800-MHz FSB) 453771-001
2.00-GHz processor (2-MB L2 cache, 800-MHz FSB) 455515-001
1.86-GHz processor (1-MB L2 cache, 533-MHz FSB) 453773–001
1.50-GHz processor (2-MB L2 cache, 667-MHz FSB) 453772-001
You have the T550 which should be the third in the list. The top one is the T7500 On page 89 of service manual you can see the various steps for replacing the CPU. It is quite complex for this model.
The max RAM for the system is 4GB of PC2-5300, DDRII (667-MHz) On page 3 and 53 of service manual you can see the various configurations.
You can also install SSD which will be faster than a mechanical hard drive. Should be 9.5 mm hard drive, most will come with adapter (small plastic spacer) from 7 to 9 mm. Page 51 of service manual.
Hope it helps,

Here's the specs:
And here is the Service Manual:
It can take up to an Intel Core 2 Duo T7500 @2.2 ghz.
It can take up to 4 gigs DDR2-667 SO-DIMM laptop memory (2 x 2 gig)
And yes it can support a 2.5 inch SATA SSD. The SATA bus is SATA-I I believe so the speed can only be so good, but an SSD would improve the speed quite a bit. Simply replace the existing hard drive with the SSD; they are the same size and shape with mounting holes in the same place and the data and power connections are identical. The hard drive has an adapter piece on it, over the data and power ports which must be removed and reused.
$6 for the processor:
$5 for the RAM:
$45 for a 120 gig SSD:
The upside potential of this model is sorely limited by its age and the obsolete hardware platform but these upgrades might make an interesting project and for $55 or so can be cost-justified.
Windows 7 is your optimum Windows version. I don't think there is video driver support for Windows 10.

Hi, @Juanedr :
Actually, you can install 2 x 4 GB of PC2-6400 memory in that model for a ttl of 8 GB in PC's with the Mobile Intel 965 chipset, even though the specs state otherwise.
But doing that would be very expensive...And the memory will only run at 667 MHz, but normally the 6400 memory is usually the same price as the 5300 memory.
Also, if you have BIOS v F.45 or newer you can upgrade to the T9500 processor.
See the F.45 BIOS release notes on the support page.

Thank you very much!
I read that information about F.58 BIOS, This said I can install a T9500! Interesting..
So, this laptop can be upgrated from:
T5550 667Mhz processor
3GB (2+1) PC-5300 667Mhz RAM
HDD 5400rpm 250GB
T9300/T9500 800Mhz processor 15-30US$
4GB PC-6400 800Mhz RAM
SSD compatible up to SATA II. 120GB 50US$
this laptop is only used for surfing internet and basic stuff,
there will be a problem if I change processor to T9300 800Mhz, and RAM works over 667MHz?
the motherboard supports 800Mhz processor T9300?
really thank you for your answers!!!

You're very welcome.
Yes, you can go to the T9500 if you have F.45 or higher BIOS installed.
No matter if you get 6400 memory or 5300 memory , the chipset can only run the memory at the 667 MHz speed.
But it can run processors with 800 MHz FSB's.
So the 6400 memory will downclock to 5300...not a problem.
And yes, unless you already have 2 x 4 GB of PC2 6400 memory available to use, I would not go out and buy it.
It would cost more than your notebook is worth.
4 GB of memory (2 x 2 GB), the SSD and upgrading the processor should really help the PC work good.
You really only need to replace the 1 GB memory chip with a 2 GB memory chip to save money.

I had forgotten about the ability to upgrade to the T9xxx series with a BIOS flash. @Paul_Tikkanen is this one of the models where you have to flash the BIOS from a Vista environment or risk damage? The T7xxx series are good processors but the T9xxx series are very good. If you can install a T9500 you should do it.

I know for sure that updating the BIOS on the dv6xxx models with the nvidia chipsets and AMD processors is the kiss of death when the BIOS flash is not run in XP or Vista.
I am not sure about the Intel models. One guy did it with no issues on W7, but I would not risk it personally.
W10? I definitely wouldn't take the risk.
