Question CPU t4400

[Howaaard]

I have a Toshiba L510 PSLQ0K-02N005 laptop with a T4400 slow as molasses in winter. Upgraded ram from 2gb to 8 and clean install windows 10 working much better but wanted to upgrade my cpu. Just for hobby and to learn a bit about upgrading laptops with pga sockets. I have gaming laptops already.
I read as much as I could find on this topic but this Korean model has almost zero literature on it. It has a GM45 chipset which should support the t9900 and correct socket so bios maybe why the t9900 won’t even boot into bios. Lights wooring dvd clicking etc but black screen never gets to bios screen and shuts off then restarts then same as above. I have seen one successful T6600 upgrade video on an L505 to T9600 and the T4400 came out in Dec 2009 whereas the T6600 was Januaryish if I recall so hoped it would work. Considering the Toshiba L505 upgrade worked is it possible to flash a bios that could recognize the t9900 or is it hopeless, never gonna work no way no how?
this is a hobby laptop so no big deal if I mess it up. Would appreciate any feedback

cheers

cpuid is same for both processors, so not bios issue, cpu simply doesnt work

updated: local tech said bad board. Considered tossing but put back together with original T4400 and booted up ok. Works fine again. Checked hwinfo and maybe problem is motherboard chipset is GL40 and I looked at the gpu info that listed GM45 and HD4500. It maybe the GL40 that I need compatibility with. T9900 and all of interest with 1066mhz bus for all the CPUs listed on cpu-upgrade cite GM45/pm45 not GL40. And on another thread on Toms Hardware below it discusses CPUs with GL40 can’t have bus speed exceeding 800mhz but cites examples of many that do work. I’ll read that thread tomorrow just glad to find out that I didn’t break anything after all. Maybe the T9900 was defective?

Is this processor compatible with laptop?

Ordered a x9000 800mhz will try that and if works monitor the temps. The T4400 runs ok but with gL40 and GMA 4500mhd barely run’s original Halo CE xp version smoothly on lowest settings . Figured an old game like that would run ok but anyway was just seeing what current capabilities were with ssd and 8gb ram. Definitely runs better than it did when I started upgrade will update when I try the x9000.

The Core 2 Extreme X9000 is 44W TDP so it may not work with the low-end Toshiba L510 (it came with a Pentium Dual Core T4400 after all). The Core 2 Duo T9500 is a conservative best bet for compatibility as it has the same 800MT/s FSB as the T4400 and not much slower than the X9000.

I still have a Sony laptop with the same PDC T4400 CPU somewhere (friend's trash a few years ago, too slow to be worth upgrading) and other laptops in the same era (T3200, T8100, SU2300). I also upgraded a Dell laptop I bought in 2006 from a Core Duo T2300E ("Yonah", not Core 2 Duo) to a C2D T7200 "Merom" three years later (paid $92 on eBay) and saw a healthy increase in speed. The marginally faster T7400/T7600 were not worth the $50+ price premium so I settled with the T7200. They all used the older FSB667 Socket M so I couldn't upgrade to a FSB800+ Socket P CPU that were faster and actually cheaper on eBay at the time.

Thanks AT i planned to try the T9500 for same TDP but saw someone was able to upgrade to x9000 and others t9500 as drop in and no thermal issues all on a gL40 chipset. I’m just dubbing around with this as a learning experience. I already have a surplus t9900 as part of that learning curve. Maybe a surplus x9000 soon. Hah…as Alf would say…. I may add a fan control program with the x9000 if it boots and runs as fan rarely even runs with the t 4400.
I have an MSI GT70 0ne 276us from 2012 still working fine but researching upgrades cpu and gpu new Msata drives etc but better to practice on these cheap machines. I have an asus G731GW-XB74 barely used not sure when I’ll use it as my go to gt70 still working great. Anyway hope to get the x9000 next week and give it a try….

Got x9000 today will give it a try asap. I had t9900 installed on it which didn’t work with gL40 chipset. Back soon with update on x9000

Edit: installed x9000 and booted. Got cmos battery failure notice again which is normal for cpu change I believe. Hit start anyway and booted up like it was always installed.

Works great so far about 39% cpumark and 50% passmark improvement. A cpumark of 1298 vs 932 i(No laughing please 🙏).

Anyway the point was to make it the best laptop I could given the starting point and to learn something so it was a success from that standpoint. In this laptop runs cool fan runs same as with T4400 but cpu is probably overkill in this laptop and can’t live up to real potential I suspect.

Overall good learning experience and practice for gaming laptop upgrade. Looking for good deals on parts for that.
