A55-S306 stuck at 598 mHz

Dear forum member,
After installing winxp on my toshiba satellite A55-S306, the speed stuck at 598 mHz. The processor is 1.50 Ghz. I have been searching online to fix this problem in the past month but I could not find any solution.
Please help.
Thank you,
~ J.S. ~

Hi
Just one question; was the motherboard replaced in the past?
As far as I know after the motherboard replacement the test & diagnostic should be performed in order to update the CPU microcode on the PCB.
If the microcode is not updated then your CPU would stuck at 600Mhz.
In order to update the microcode, the ASP must be contacted.
The other reason why the CPU runs only at 600Mhz is the low CPU processing setting in Toshiba power saver.
Check if the Toshiba power saver is installed on your notebook and set the options to a higher level.

Intel T7250 stuck at 1197 MHz

Hi guys.
Finaly i'm able to write at this forum.
Any way. I have a old T61 laptop which i'm running Win 7 on. It works great except one problem.
My CPU seems to be stuck at 1197 MHz, and i've tried everything.
*Bios is up to date
*Speedstep is disabled
*Maximum performance in power management, both Wiundows and Lenovo Power Manager.
Both the bios and Windows tell me that my CPU can run at 2 GHz, but that not possible atm.

I have a T61 running on the 45N0121 charger at 65 watts and it's T7350 processor is running right now at 1995 MHz, just short of it's advertised 2000 MHz. Frequently, CPUs do not run at their advertised speed unless stressed (working hard).I do not believe you need the additional wattage to get full speed. Stress the CPU and check the speed. However, if you really want to try the 90 watt "solution", I saw the 90 wattcharger on Amazon.com for less than $9. It might be worth purchasing.

Portege M200 - CPU runs only at 598 MHz ! Toshiba DOS Base Service Tool

Portege M200 - CPU runs only at 600 MHz
I have a Portege M200 with a Dothan Pentium M 725 supposed to run at 1.6 ghz but posts a 598Mhz
clockspeed. I updated the bios to 1.8.
I read in a previous 'locked' post ...... :
http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=63390
...there is supposedly a DOS base utility from Toshiba to solve the issue. .
it is said it is not a Bios issue.....................
Can anyone direct me to this utility?
Thanks!

The answer is here...thank all and whoever is responsible:

The key is a utility called ' pom200t1 '
You will need the following.
A floppy or if you don't have one an external floppy drive, or if you are savvy to be able to boot a file from a CD-Drive.
You will also need WinImage as all the files you download come as .ima files
Download pom200t1-V1.5.zip and pom200t1.zip (if one doesn't work the other should).
You can find them here:
http://www.stormpaintball.com/toshiba/pm765.bin (this one is a last ditch attempt).
Then follow these instructions from the site I posted before:
Symptom:CPU stays at 598 MHz constantly.
*Procedure:*
1) Boot into BIOS. (Press "Esc" during the boot process, before the OS loads, but after entering your password, if you are using boot-time password protection).
2) Look under the "Others" category.
3) If the motherboard doesn't have enough information about the CPU, the category "Dynamic CPU Frequency Mode" will be blanked out (you won't see it).
If the laptop is in this condition it will never go faster than 598 Mhz until you perform the following procedure.
Note: Although this utility says that it is for a Toshiba Portege M200, the particular fix you need might work on other Toshiba laptops.
It has worked on 3 different Toshiba Satellite Pro M15 S405s, but *USE AT YOUR OWN RISK*.
1) Boot into Windows and create the bootable floppy disk from the pom200t1.exe file.
2) Boot from the floppy disk you just made.
3) At the menu select option 2 "Repair initial config set"
4) At the next menu select option 1 "Initial cofiguration" (misspelled)
5) After a few seconds you should see "Writing a file was completed!" and the laptop will automatically reboot without prompting.
6) When the laptop reboots go back into the BIOS and look under the "Others" category. You should now see the "Dynamic CPU Frequency Mode". Make sure it is set to "Dynamically Switchable" for CPU throttling.
7) Reboot into Windows and verify the CPU can throttle in the normal manner. The Intel SpeedStep Technology icon should now be in the systray. Go into the Toshiba Power Management / Power Saver Properties and update all of your Power Save Modes to use the SpeedStep Technology you prefer (Fixed or Automatic), and bump up all the processor speed caps, or you won't be able to go above 798 MHz because the sliders will still be at their old settings (4 or less), whereas they can now go up to 7.Let me know how you get on.
I've fixed the CPU now just need to find out why my fan only works when I manually activate it!??

MSI GE70 Doesn't Boost, Stuck at 745 Mhz (650m gpu)

hello, i bought my laptop yesterday and i figured out a strange thing. my gpu won't go above 745 Mhz even if i play games(dota2, bf3). as far as i know it should boost to 830Mhz. i google'd it and found out that some dell owners had that aswell and a bios update for dell solved that. is there any msi bios updates on the way? or is there any other solutions for my problem?
here is a quick summary of what i did so far: after i found out that i have a problem, i ran some oc softwares to boost it manually;
-msi afterburner: didnt work at all, gpu clock stuck 745 mhz,
-nvidia inspector: very weird but i tried almost 20 times to work this but only 2 times it worked(850 mhz) and after restarting pc, i tried to work it again, but it didnt.
i also asked some other ge60-ge70 owners on a turkish forum, half of them have this no-boost issue aswell.

yes that's normal, dx is basic info and don't shows discrete cards.
remove current vga drivers in safe mode with >>Driver Fusion<<
then reboot to normal mode and install those drivers:

PowerBook G4 12" stuck at 533 MHz

Hello all,
My wife's 12" PowerBook G4 867MHz seems to be clocking itself down. Energy Saver is set to "Maximum Performance".
When I reset the power manager, it shows 867 MHz again (and is noticeably faster). However, after a while it slows down again.
$ sysctl hw
hw.cpufrequency: 533333332
hw.cpufrequency_min: 533333332
hw.cpufrequency_max: 533333332
The battery is long gone (though when you press the button on the battery, it shows 5 lights). The machine crashes a lot, and seems to run pretty hot - both temp. sensors usually report 50° C. It also makes clicking noises from the speaker periodically.
Any ideas? Is this an OS bug or a hardware problem?
Thanks,
Seth

On further investigation, the following seems to occur:
After PMU reset, sysctl reports the correct processor speed (867 MHz).
After reboot, sysctl reports the wrong processor speed (533MHz).
However, the PMU reset seems to have done two other things, both of which are quite nice:
#1 Processor speed cycling works now (it didn't before). With Energy saver set to Maximum Battery (Reduced CPU on battery, Highest CPU on AC), the machine clearly bumps up to 867 MHz when the power adapter is attached - the benchmark I'm using to determine actual speed shows a 60% increase.
#2 The battery works again. Prior to me trying to fix this problem, the battery (which is still the original 2005 battery) was totally dead. Unplugging AC meant the PowerBook would turn off immediately. After resetting the PMU, the battery seems to be holding a charge again - the machine has idled for at least 20 minutes, and still shows 89% power left. My understanding of modern rechargeable batteries is that they work for a certain number of charge cycles, then they stop working. This battery has been dead for a long time, this defies explanation. I can only guess that whatever was messed up in the PMU caused the computer to stop trying to recharge the battery.
Anyway, problems solved here.

W530 K2000M stuck at 405 MHz

Yesterday I flashed BIOS 2.58 and enabled Optimus again in the BIOS. But I noticed the K2000M is always stuck at 405MHz when the discrete card is being used. I have tried several games and benchmark suites, ...
When I enable discrete mode in the BIOS it's working correctly.
What I attempted:
- Latest driver supplied by Lenovo from support.lenovo.com
- Latest ODE driver from www.nvidia.com
I assume this issue started with the latest BIOS version, is there any chance I am correct?

Thanks I will try that application. Seems quite useful
I fixed my problem yesterday. Apparently it was caused by a corrupt installation of Lenovo Settings Dependency. Reinstalling that fixed it. Lenovo Settings Dependency failed to install on N and KN editions of Windows because it requires the media feature pack. Apparently that was the root of the cause.

Black screen problem on A55-S306

This is going to be a long post because I have done a lot of troubleshooting and have come to the conclusion that the problem I have is system board related. I have two computers that are identical except one is a celeron and the other is a centrino. I have tried swapping all the related parts from one to the other but still have the same problem. The centrino machine has a black screen. The image is there. I can see it with a flashlight. It works fine with a monitor hooked up. In fact I am writing the post on it right now. So my question is this. If it is definitely the system board, can the board be repaired? I can probably find a board on ebay but would like to know first if this one can be repaired. What usually goes wrong on a system board that would render the screen dark. It has to have something to do with sending a signal to the flourescent light bulb. I have tried the cable, the inverter, the bulb and finally the screen. They all work on the celeron machine. Can anybody give me any advice as to what to do. I am trying to get both machines working so they can be donated to a couple of elderly folks where I live. I am elderly too but I am still trying to be viable and useful. Help!!!
Ray

Great job on the diagnostics! Typical lack of a backlight is caused by the screen, FL inverter or the cable between the system board and the FL inverter. But if you have eliminated all of those it has to be the system board. One other place to look, depending on the computer, but there is a switch somewhere that lets the computer know that the lid has been lifted. In the old days, it was a small pin that went up and down to control the backlight. The new switches have no moving parts but use a magnet in the lower edge of the LCD screen to turn on and off the backlight. You should be able to find the magnet with a small piece of steel. If the magnet is missing or moved, it could cause the backlight not to work. Check the working computer to find the magnet and compare it to the one that isn't.

Y40-70 AMD R9 m275 stuck low MHz problem report

My laptop y40-70 has 8G RAM, i7-4510u, R9 m275x 2G, 256G SSD. I have both win8.1 and win10 installed right now. have 3 problem to report.
Problem 1: after receive 15.200.1046.2 driver on my Lenovo Y40-70 windows 10 10240build , I got infinite blue screen on every boot up with message"internal power error".
I already try reinstall windows 10, I try install video card driver from official Lenovo support for Y40, the driver vision is 15.200.1050, no blue screen at all and it would makes the windows updata auto skip the new 15.200.1046.2 updata. I also try reinstall windows10 and just let windows updata download and install all drivers, the blue screen comes out again after it install the new 15.200.1046.2 driver.
Plz fix this.
Problem 2: this problem exited for long times ago, the AMD R9 M275 on Lenovo Y40-70 randomly drop/stuck low frequency around 300-400Mhz within some 3D games, mostly in GTA5 , by random, I mean, random. Like in GTA5, GPU-Z shown that it sometimesdrop and stuck to 300 Mhz at only 68℃, which is like just start the game 3 mins, and the game drop to 14fps; But sometimes even start the game for 1 hour, and the GPU gets 85℃, it reminds 925Mhz, the game would stay above 30fps.
This problem not only happened to me, but also a lot of Chinese Y40 user, if you go 百度贴吧and go Y40贴吧， you could find many people have the same problem.
and in Lenovo NA forum:Y40 r9 m275 stuck at 300 mhz - Lenovo Community people have the same issure but Lenovo does not give a sht.
please dont tell me to plug in charger set high performance those kind of stuff, I already did, and I install all drivers from official Lenovo Y40 driver support site and AMD driver site.
Problem 3: with Official 15.7 driver installed (15.200.1046.0) from AMD driver site ,
In windows 10 10240, GTA5 laggy as hell when scene change fast such as driving, but when you slowly or evern just stand, the fps would remind steady with no lag.
In windows 8.1, GTA5 no lag at all with the same in game setting as in windows 10, besides the GPU random drop low Mhz problem, tha game runs smooth.
please fix these annoying problems. SRRY for my bad English.

Stephen,
You report is a Kernel Panic report. It appears your computer is crashing when OS X "sees"
com.avatron.AVExFramebuffer 1.7
com.avatron.AVExVideo 1.7
I would recommend either updating the apps that use those files or following the developers instructions or uninstalling them. It also appears you have upgraded the RAM on your computer. Kernel Panics can frequently be RAM related and iMacs are sensitive to RAM. The causes can be:
Incorrect RAM
Failed RAM
Unseated RAM
You can tell fairly easily if the KP is caused by RAM by removing the upgraded RAM and running with the original Apple RAM. If the KP's disappear you know it's a RAM issue, then it's a simple matter of determining which of the three RAM problems it is.

Portege M100 with PM 1,2 processors, but only run on 598MHz

Please help, I have 10 pcs M100, and 7 of them have no setting in Bios for "CPU Dynamic Frequencies Setting" (set the CPU speed, always low, always high, dynamic). The notebook that don't have that setting always run at 598 MHz. I already check with Sisoft Sandra and in windows system properties. The properties always show that the notebooks have Pentium-M 1,2GHz running at 598MHz. No different between running with ac adapter or battery.
The other one with the CPU Dynamic Frequencies Setting, can dynamically adjust the CPU clock. They can run at 1200MHz normally.

Hi
The Dynamic CPU Frequency mode is available in the Toshiba HWSetup.
There you can switch between the dynamically switchable mode, always high and always low mode.
Please check it!

NB voltage control not working

I'm on a 790XT-G45 (2.5 BIOS although I have tried other BIOS') which supposedly supports a 2600 MHz NB. There is nothing I can do to even get the board to post with a 2600 NB and raising the NB voltage doesn't seem to do anything either. If I can get into Windows (only sometimes) @ 2400 MHz NB, and then increase voltage through overdrive, it stays stable.
So the question is how can I raise the NB voltage on this board? The BIOS setting that raises NB voltage in conjunction with HT link doesn't seem to really do anything.
Otherwise does anyone know a way to get Overdrive to allow you to change the NB multiplier so I can just overclock it in Windows? I'm not happy with a 2400 NB and even worse it hardly will ever get into Windows with stock voltage and this frequency so really I'm stuck below 2200 MHz.
Should I RMA the board?

Quote from: wlahdone on 13-February-11, 21:31:36
I have opened up AMD Overdrive ,Enabled Advanced ,Clock voltage andi see CMOS Items-> CPU NB Multi and NB Vid present ,but i presume you need to enable ACC to change them.I did not play with this values though.I have never gone to more than 2400 M with my CPU on any motherboard with mild voltages for the NB.But either the BIOS menu would freeze either Windows freezes.There is an increase in the speed games are loaded but thats it .I doubt you can achieve more on another motherboard.You are beating a dead horse in my opinion.Do some CPU clock overclocking better with a proper cooler.Try a 1T timing for RAM and you will get more on the memory performance side.
I have all those enabled and I still cannot access the cmos items section. Can you tell me specifically what you have set? I can adjust NB VID under the voltages section but I cannot adjust the mutiplier in the CMOS items section.
MANY, MANY users are reporting having ABSOLUTELY NO PROBLEMS getting a 2600 MHz NB-CPU frequency, and many are pushing that easily to 2800 and even 3000 MHz. According to AMD themselves, (http://sites.amd.com/us/Documents/AMD_Dragon_AM3_AM2_Performance_Tuning_Guide.pdf, scroll to the bottom), you can expect 2800-3000 MHz on the NB link, with 1.35-1.5v - basically you can run your NB voltage as high as your CPU.
As far as overclocking, I am pushing 4.2GHz, on high end water (CPU & GPU) and I have added MOSFET coolers to the board so I'm pretty sure I'm good. Regardless I would like to push the board as far as it will go, and even at stock frequencies, and two different CPU's, I cannot get the NB frequency stable above 2300 MHz or so. Look it up, people are reporting better performance with a higher NB frequency, especially with higher clocked modules and overclocking.
All I'm expecting this board to do is what all the other boards can do - to be able to increase the NB frequency to at least 2600 MHz. If I am beating a dead horse, it's because MSI users have given up and accepted lack of support as a status quo. It would probably take no time at all to add a NB-CPU voltage adjustment to the BIOS. And yes I have contacted them so we'll see what happens. If this board is supposed to support up to 5200 M/T, then I would like to see it.

PXE-E61 error, but my HD is OK

My laptop is a Satellite A55-S306 which, until yesterday, has given little trouble in the past. I have not added new hardware, nor have I modified the boot order.
I am getting a PXE-E61 Media Test Failure when I power up the machine. It also says that the \WINDOWS\SYSTEM32\CONFIG\SYSTEM file is missing or corrupted, but this message only appears after the PXE-E61 failure message. The problem occurred while I was out of town and the system hibernated, but it probably came awake to service an automated JungleDisk backup. When I returned, the system was powered up with the "SYSTEM file corrupted" message on the screen.
I don't remember with certainty how to get into the boot order menu, and have not been able to. I am able to get into the pre-boot setup menu using Esc, and it has lots of options, not including boot order. I have tried various F keys, including F2, F8, F10, F12, but these seem to do nothing.
In any case, I think the boot order is working, because I am able to load a CD and boot from it.
I have SeaTools on CD, and I used this to test the hard drive (long test). It passed with no errors detected, so I believe that the disk drive is available and the formatting is OK.
I also have an Acronis recovery CD, with their Disk Director and backup applications on it. Booting from this, I am able to see the C: partition on the hard drive. Using the backup application, I am able to explore the various directories and they look normal. I even commanded a full backup of the C: partition to an external USB drive, and this completed without error.
About the only thing I can think of is that there is a problem with the boot sector on the hard drive, or the Windows system files have been corrupted somehow. I have not been able to command an fsck on the drive, because I don't have that on bootable CD and haven't been able to get far enough on the HD to do so. I tried using Acronis restore to copy the old version of the SYSTEM file, but this failed with some wierd messsage.
I can restore C: with an Acronis full backup from last month (made with the Acronis bootable CD), but is there a way to avoid rolling back that far? And I'm not positive even this will solve the problem.
Suggestions would be appreciated!
Solved!
Go to Solution.

Thank you very much, anarchy_1024, for your advice -- it was most helpful. Now for the rest of the story:
I attempted to restore the entire \WINDOWS\SYSTEM32\CONFIG folder from Acronis full backup, but it insisted (correctly) that the folder was corrupted. So I went looking for a chkdsk that I could run from CD, since I could not get XP up to command it from there.
I ended up downloading and building an Ultimate Boot CD for Windows (UBCD4WIN), and ISO Recorder to allow me to burn the resulting ISO file to CD. This took a while, but gave me an XP system on CD with lots of diagnostics, including chkdsk.
Using the A43 File Management Utility to view C:, a spot check revealed no problems *except* for the \WINDOWS\SYSTEM32\CONFIG folder, which couldn't be viewed because it was corrupted. I ran chkdsk and it found several index errors and recovered 22 "orphaned" files, which appear to be the contents of the corrupted directory. Finally, I ran MemTest86, which found no errors. After all of this, I rebooted to the hard drive and it came up fine! It has been an arduous odyssey, but the bottom line is that the system is recovered (crossing my fingers when I say that), and I did not have to fall back to a 3-week-old backup state. I still have no idea what caused the folder to be corrupted, but it probably should reinforce the notion that one should run chkdsk on the system disk periodically.
One anomaly is that the PXE-E61 error is still there, but then XP boots up fine. I expect this is because my boot device order includes some device, USB or CD, before the HD, which causes the error, but then the boot sequence finds the HD and all is well. I just never noticed this error message before, since it never caused a problem.
At this point, I would recommend anyone build and keep a UBCD4WIN CD around, just in case. I will mention 2 glitches in building it:
1. Like probably most consumers, my system didn't include a Windows Install CD. BUT all the install files are on the hard drive, in C:\I386 (this is an old Compaq system). All I had to do, in the UBCD4WIN build program, was to specify "C:\" as the Windows source directory, and all went well.
2. My first build of UBCD4WIN was too big for a CD. Since I didn't have a DVD burner handy, I did another build, disabling stuff I didn't plan on using (Firefox and Spyware software, mostly), bringing down the ISO size to under 600 MB, and that worked fine. It is very easy to do consecutive builds, customizing between builds, since the builder stays up until you close it.

Satellite A50 1.6Ghz cpu only running at 598Mhz

I have a friends satellite A50 here, he said it was running slow!
XP reports the cpu @ 598Mhz, Everest reports that multiplier @ 6 X 100Mhz.
Could someone please explain how I can get this laptop up to speed?
I have found other people with the same problem but cannot seem to find a solution .. :(
Any help would be much appreciated :)

> I have found other people with the same problem but cannot seem to find a solution
Please use search option on this forum and you will find enough topics with very precise explanation why the notebook runs on 598 MHz only.
I can say just one thing: it can not be that notebook runs like this from the first day. If your friend sold you this notebook he conceals something from you. Anyway contact nearest service partner in your country and they can fix this for you.

945P Hangs @ 225FSB

I got a computer for free:
Specs:
-E4300 @ 1.8 Ghz (9 * 200 MHz FSB)
-MSI 945P Neo 3
-two no-name http://en.wikipedia.org/wiki/No-Name sticks of DDR2: 667MHz
-GeForce 6600 ( to be replaced with 4850 once the OC is worked out)
I did what I thought was enough homework http://en.wikipedia.org/wiki/Homework and found my board to be limiting at 300FSB. Okay, 2.7 GHz is enough for me.
I went out and bought two more sticks of RAM. This particular board can only take at most 667Mhz ram so by my thinking 667/2>300 thus I'd be fine.
I bought an OCZ http://en.wikipedia.org/wiki/OCZ_Technology Vendetta 2.
The Problem: My FSB maxes out @ 224 MHz. It hangs @ 225.
Latest bios installed. Northbridge seems hot @ mid 20's. CPU barely breaks 20'C under load. If I can't figure out the problem I might bring the Vendetta back and OC with the stock cooler...
Am I missing some settings in the bios? It seems kinda limited...
The 1.55 V seems to correspond with my PCI-E voltage. The reported vcore of ~1.23V in MSI dual core centre is 1.384V in bios @ idle.
Could the RAM be bad..? I tried booting with only one stick with similar results.
I can't figure out how to raise the core voltage, either. Neither the bios or dualcore centre allow such changes.
In need of a 'lil direction,
Thanks,

Okay, let me try to explain it in a little more detail:
The memory frequency values that you can set in BIOS (400 MHz, 533 MHz, 667 MHz etc.) are only valid when your system is not overclocked. Behind those values there are fixed FSB/Memory Ratios. For an FSB-200-MHz-Processor, these values are:
- 400 MHz ----> FSB/Memory Ratio = 1:1 [200 MHz FSB x 1 = 200 MHz (=DDR2-400)]
- 533 MHz ----> FSB/Memory Ratio = 1:1.33 [200 MHz FSB x 1.33 = 266 MHz (=DDR2-533)]
- 667 MHz ----> FSB/Memory Ratio = 1:1.66 [200 MHz FSB x 1.66 = 333 MHz (DDR2-667)]
So, if memory frequency is set to 667 MHz in BIOS, that means that the 1:1.66 Ratio is active. As long as the FSB Clock Speed is set to 200 MHz (default), memory clock Speed will be 1.66 x FSB Clock Speed which results in 333 Mhz DRAM frequeny which effectively means DDR2-667.
Now, if you raise your FSB Clock Speed to 225 MHz the result of FSB x 1.66 will no longer be 333 MHz (DDR2-667) but it will become:
225 Mhz x 1.66 = 373.5 MHz [= DDR2-747]
As you can see, your memory is overclocked. Set FSB Clock Speed to a stable value (does 215 MHz FSB work okay?) and set Memory Frequency to 667 MHz again. After that, boot into Windows, run CPU-Z and click on the "Memory" tab. You will see that the memory frequency is not @333 MHz (DDR2-667) but actually @215 MHz x 1.66 ~ 357 MHz [=DDR2-714]. I am telling you to check this for yourself as it will help you to see what I am talking about.
Okay, what would happen if you lower Memory Frequency to 533 MHz? FSB/Memory Ratio will now be 1:1.33. That means @225 MHz FSB Clock Speed, your memory will run @225 MHz x 1.33 ~ 299 MHz [~DDR2-598 MHz]. Your memory will now reach DDR2-667 Mhz again if FSB Clock Speed reaches 250 MHz:
250 x 1.33 = 333 [DDR2-667]
That means to be able to go higher than 250 MHz FSB Clock Speed without overclocking, you have to decrease memory frequency to 400 MHz (1:1):
250 x 1 = 250 [DDR2-500]
You will reach DDR2-667 clock speed again @333 MHz FSB Clock Speed (if you should get that far):
333 x 1 = 333 [DDR2-667]

M200: Processor works only with 600MHz - Why?

I have observed that when you change pcb set for a laptop irrespective of the processors speed it runs at slowest that is 595/598 MHz.
Have you observed this? What is the reason behind?
What is the solution?
If the processor is having 256MB/512MB RAM this things wont affect a large but for 1GB & 2GB the machine performance become very problematic.
I have tried updating DMI this didnot helped.
Re-installing os also didnot helped.
BIO upgrading also didnot helped.
I'm also not very sure about this problem having any relation to pcbset change.
With the good machine I have found the way is dynamically switching capabilities of a processor from bios.
In few machines that are giving problems i didnot observed this option in BIOS.
The machines are PortA200 & Port M200(tablet).
can any one help me. I need to justify this to customer.
Thanks & Regards

Hi
This issue occurs after motherboard changing. Usually after mainboard changing it is very important to make any tests and diagnostic procedures. Without this procedure the CPU will work only with fixed 600 MHZ.
You should contact the Toshiba service to solve this CPU issue.
