Satellite U400 (PSU44E) randomely rebooting

Hi Everybody,
I have a strange problem on my Satellite U400.
For a couple of days it was starting sending blue screens and rebooting.
I used the Vista memory check tool and identified one faulty RAM.
I changed both with OCZ 2*2Go PC6400, and no more problems according to the vista memory check tool.
But now, sometimes it works fine, sometimes I have blue screens and even sometimes it is rebooting wothout bluescreen just like that...pshh...
The other thing I noticed is that I have some times some strange lines appearing randomely on the screen like a bad contact....
I have updated the drivers of the motherboard, the diplay, and the BIOS...
I have no more clues....
Has someone an idea?
Thanks,
Furby

Hi
First of all the links to the images dont work.
Secondly it would be interesting to know if your warranty is valid.
If yes, then you should contact the ASP in your country before you would replace any RAM and other hardware parts. Usually the warranty should cover such replacements.
Ive got a U400 too and my notebook is running fine. I upgraded the RAM too but I used the DDR2 667MHz (PC2-5300) 200-PIN SODIMM modules.
I dont know why you used the PC6400 (800Mhz) but maybe this issue is really related to the RAM issue.
Possibly the higher temperature could affect the functionality of the modules which would lead to the BSOD.
Did you notice an higher temperature inside the notebook?
How about fan cleaning?
You could remove the dust from cooling grilles using the compressed air spray
I think its worth a try

How do I remove Vista from Satellite U400 PSU44E and install Win XP

Because much of my specialist software is designed to work with XP pro I need to remove Vista Home Premium from my U400 and install XP Pro. As others have found with other Toshiba models simply placing XP disk in the DVD drive results in 'the dreaded blue screen' with error code 0X0000007B (0XF78D2524, etc etc) and comments about hard drive properly configured / check for viruses/run Chdsk/F to check for corruption.
Changing HDD BIOS from AHCI to compatability mode allows XP disk to load and run as far as 'Press enter to load XP' but pressing 'Enter' does nothing; pressing other keys has no effect either and the only way out I have found is to press and hold down the On/Off button. Also re changing from 'AHCI' to 'Compatability ' there are many comments on other Internet fora suggesting that using Compatability mode makes disk access much slower than the AHCI mode. However despite searching the Web using Tosh HDD Model Referencee No (MK3252GSX) I cannot find a XP ATA driver to nLite into XP before trying again.
Can anyone tell me a procedure they have used to strip off Vista and replace it with XP Pro on te U400 PSU44E please?

A friend of me has a Satellite U400 too. He installed Windows XP in AHCI mode and he doesnt have any problems.
As Juan28 posted you can integrate the drivers by using nLite. This tool is freeware and pretty easy to use. You need only the original Microsoft installation disk and the SATA drivers that you can download on the Toshiba website:
http://eu.computers.toshiba-europe.com => Support & Downloads => Download Drivers
If you dont want nLite you need an external FDD. After booting from CD you must press F6 to load the drivers from the FDD.
I prefer nLite because so I dont need an external FDD.
Furthermore I have read in the forum that the AHCI mode is a little bit faster as the compatible mode but in compatible mode you dont need any additional drivers for SATA.

Re: Satellite U400-Joo: Number appears instead of letter

Can some one plz help me , its killing me :)

i found a way to stop the num-lock turning on when the laptops where rebooted or shutdown....
Navigate to the following key in the registry - HKEY_USERS\.DEFAULT\Control Panel\Keyboard
change a value with the following details:
Data type: DWORD
Value Name: InitialKeyboardIndicators
Value: 0 = NumLock is turned off after logon, 2 = NumLock is turned on after logon
Restart the Laptop for these changes to take effect.

Satellite U400 will not usually boot up

Hi all,
I have a Toshiba Satellite U400-217 (PSU44E) running Windows 8.
Worked fine until a week ago. Now, when I switch it on, the indicator lights light up, there is a brief hard drive spin (1 second) - and then nothing. The lights above the keyboard stay lit, but the screen stays black.
I read a reset remedy where you take the battery and power cable out and hold the power button for 30 seconds, then plug the power cable back in, boot up, shut down, reinsert battery and boot up again.
However, the machine will still not boot up after the 30-second button hold. I still just get the lights and nothing else.
However, the machine will generally boot up fine on one attempt out of every 30 or so.
It's annoying - any ideas or suggestions very gratefully received.
Many thanks,
KaiBosh

> However, the machine will generally boot up fine on one attempt out of every 30 or so.
In my opinion you should firstly check the HDD
A friend of mine installed Win 8 on new notebook from another manufacturer
After some time the notebook could not boot up I thought its something wrong with motherboard but finally it was just an HDD malfunction
To be honest I dont know if its only HDD issue but in my opinion the HDD is one of the first parts which should be checked
Ok, in worst case it could be possible that mobo malfunctions.

Satellite U400 wont turn on & when on wont come back from sleep mode

I have a Satellite U400 and its a year and a few months old.
In the last little bit it has been acting up, and it started with when the computer goes to sleep and goes to the black blank screen it will not come back from that.
The only way to do anything is hold in the power key till it turns off and then turning it back on. This brings me to the warning screen I have turned my computer off incorrectly. It has been doings this for a few weeks and started randomly out of the blue.
Then just today it wouldnt turn on at all, I was pressing the power key and the key itself would light up, and on the bottom right hand side the little lights would light up but wouldnt turn on, I kept pressing it over and over and over again and finally it did turn on. Once on I only used it for a few mins before turning off again and then would do the same thing, I kept pressing the bottom till it turned on. Its been on now and hasnt turned off again.
Not to log ago I had to reformat my computer due to me forgeting my password and had locked myself out of the computer. About a week after that is when the issues started. I am not all that computer smart, to be honest, I do understand something things, I can follow step by step to do something.
I really dont want to pay to have it fix I want to just do it myself and soon as its in great shape and never had any issues before.
Does anyone have any idea what this could be, or why it could be?
I am thinking about reformatting again as I am worried that didnt work out right the 1st time or something.
Or if this is something that needs to be repaired does anyone have a clue on the cost of it?
Thanks ^_^

hi aev270,
sounds like a serious problem to me.
try the following: take out battery, cd-rom, hdd and try again.
if it starts up without this components - you got lucky!
this means it probably a software issue (but i dont think so - sorry)
do you see the toshiba logo / bios messages? no - the you are in trouble.
this strange behaviour could depend on many things: defektive components like ram or grafics... or (badest thing) the mainboard...
if you have still warranty on it you should go to a servicepartner having the system checked.

Satellite U400 - Slow connection on Windows 7

Hi
I use Satellite U400.
And I can't install wireless driver I dont know why. I open the file and it just won't install but still I think I have the latest drivers for my wireless network,
but my serious question was: why I drop and limit bandwith with windows 7 but not with winXP?
I have 1Mbit/s but example I want to download firefox go to their website's and then it shows between 50 and 70Kb/s but sometimes it gets to my normal max high 120Kb/s, and I saw on google that alot of people have this issue.
And sometimes some website are not loading or I just got error because of so slow connection that websites just turn off :(, never happend before.
plz someone help - any suggestions plz?

> what kind of forum is this? no help for more then one 1 week , more then 10 days now ?
What are you expecting? This is a user to user forum if someone would like to help you then he will post in your thread.
In most cases such themes has been discussed a lot of time here maybe you should not wait only for someone but should use an advanced search option and could search and read in similar threads for possible solutions
Regarding your issue:
> i do have the latest updates and still nobody from you tried to help me to get a fix , why dont you guys belive it? when i said look at google.com and write windows 7 wireless probblem or slow down my wireless, this is a KNOWN issue with windows 7 .
Firsty you said that you are sure it's Win 7 issue
>i have asked around everywhere and they all say it is NOT windows 7 issue it must be the manufacter driver issue .
Now you are saying it;s notebook issue....
So what is your possition now????
How it could be a manufacturer issue if the speed is faster using WIn XP??? For me it make no sence...
However, I googled a little bit an found this:
Tweaking Windows 7 for Faster Online Connections
http://www.brighthub.com/computing/windows-platform/articles/58522.aspx
You can also try to speed up the IE 8
For that use the command: regsvr32 actxprxy.dll
This should be typed in RUN
Then reboot the notebook.

L305D Random reboot

I have a laptop Satellite L305D. The OS is Windows Vista Home Edition. It keeps random reboot frequently. Is anyone has the same problem? Can I share some solution information?

terry4274 wrote: In this case, can I get some error logs?
When you get a random reboot, make careful note of the time. After the reboot, click on 'Start', type in Event, click on Event Viewer, click on the arrow beside Windows Logs, click on 'System', wait a little while for it to compile the log.
Then, scroll down until you're seeing the events just before the restart, right when the system randomly rebooted, look for any strange events (probably with a red or maybe yellow asterix mark). Double click on those events, click the 'Copy' button, the past them into Notepad, except edit (cut) everything out from 'Event Xml:' and below. That is we only want what's above 'Event Xml:'.
Attach the txt file here with these events, or if there's only one or two, copy and past them here.

Portege M800 now is Satellite U400

After Motherboard Replacement everest for windows reports my M800 as a Satellite U400. Can I modify this ? or i return my laptop to the service center.
Thanks

I think the DMI information needs updating. The service center should have done this when the mainboard was replaced, so take it back to them and ask them to update it.

[nforce] K7N2 Delta, having massive lock-ups / random reboots.

Hi all, it's been a while since I last needed your wisdom. Anyway, a couple of days ago my machine began to randomly reboot on me, so I went about trying to figure out what is causing the problem. I've cycled out my PSU, my drives, changed BIOS settings, so on and so forth, and it's still happening. System Specs follow:
MSI K7N2 Delta Mobo
Athlon 2800+ Processor
512 x 2 Kingston ValuRAM PC3200
Generic PSU : 3.3v : 28a, 5v: 30a
EVGA Nvidia Geforce 5950 Ultra 256 MB
Seagate 200GB 7200 RPM Hard drive
Lite-on DVD/CDRW Combo burner
Any ideas? I've been dismantling this thing and rebuilding it over and over for about a week now, and nothing has changed. I get the reboots all the time, graphic-intensive and not. I've even had the machine freeze up in the BIOS menu before. Help me please!!!

Alright, thanks a lot guys for all your help!
Hi there..
I'm not sure if you have fixed the problem or not.....but i have the same board and my pc reboot maybe one or two times a day...
and i'm sure it is my Ram, and i also use 2x512mb Kingston Value pc3200
i have tried with 2x512mb crucial pc3200 from my other pc and then there is no problem...
ps. I haven't been writing in english for a long time.

Battery issue on Satellite U400

I bought my Dad a Satellite U400 10J laptop for his birthday just under 2 years ago. Being over 60 and not too enthusiatic about using a laptop, he left the unit in his cupboard for close to a year before turning on. The first problem materialsed with the laptop not turning on with the "Battery not recognised" error. Subsequent updating of the BIOS got the laptop to startup. However, despite now charging (or appearing to charge) the battery only retains about 10 minutes of charge. This has progressively gotten worse to the point that the only way to use the laptop is to keep it constantly plugged in. Which as you can imagine, limits the utility of having a laptop in the first place.
I did take it back to the retailer and since I had purchased a warrantly extension, was hoping that they would replace the battery. They refused indicating that the battery is not covered and that by not using the laptop intitially after purchase, I had in effect damaged the battery.
Is this possible? Can a battery to irrevocably damaged through inactivity? I think that the period was around 9 months during which he had not even unwrapped it from the box.
If it is, are replacement batteries an option or should I order an orginal Toshiba battery? Also, are there extended life battery options available for this model?
Thanks in advance

yes, it can take place. It's recommended to charge the battery full even if not used. You should use original Toshiba batteries Don't think that there is extended life battery option available

Wireless issue with Satellite U400

Hello guys,
my laptop is Satellite U400-10n. (OS Vista)
It was running perfectly. But now I cannot connect to a wireless network. When I search for a wireless network, sometimes nothing comes up. I'm using cisco network magic program but it didn't help. I tried everything. I disabled the Bluetooth devise. I turned off all the Bluetooth devices around (cell phones). I have a cordless phone; I turned it off as well.
I tried to update the wireless network device, but didn't help either.
Please guys I need your help.

For WLAN configuration you don't need to use additional applications and you can configure it using Windows settings.
Anyway, check all WLAN settings. Be sure the WLAN card and your router uses the same WLAN standard, try to restart your router.
Have you tried to connect your notebook to some other WLAN?
Can your notebook detect other WLANs?

Bluetooth on Satellite U400

Hi
I recently bought a new Satellite U400-15e and assumed it had bluetooth installed. After switching on the communication switch I set my phone
to search for devices but it found nothing. I tried searching a few times with the same result. So I now assume that bluetooth is not installed
on my U400
Can some one tell me how I go about getting and installing bluetooth on my laptop.
Many thanks.....Bill
ps. Is switching on the communication swith all I need to do to activate bluetooth?

Is switching on the communication switch all I need to do to activate Bluetooth?
No. when the WLAN switch is set to ON you must enable BT using FN+F8 key combination.
After doing this for the first time BT software will be installed and T module will be configured.
When finished you must start BT software end configure it with your external device.

Wireless connection is not working on my Satellite U400/03S

Hi Guys,
I have Toshiba Satellite U400/03S laptop and I have a very strange problem that I can't seem to get around.
I signed up new ADSL2+ connection and yesterday when was I trying to setup it up I found the I can connect to internet through wired but not wireless.
The laptop shows the network in the list with full signal strength. I have configured the connection properties identical to my laptops including the WEP key and such. When I go to connect to the network, it just sits and says "Waiting for network" for approximately 5 mins, then that dialog dissapears and never connects to the network, just goes back to the network selection screen.
Has anyone had this problem? If so how did you go about fixing it? This is very frustrating and have been playing with router options and computer options for hours now trying to get it to work properly with no luck.
Just to let you know guys that I am using Billion BiPAC 5200G RC wireless router and windows XP pro on my laptop.
Help please! Thanks in advance to all that reply.
Sam

Hi buddy,
I agree with Macius. You should contact your internet provider because I think its a problem with your Internet connection or router that you get from them. So you can check with the guys step by step if everything is configured properly.
For creating a WLAN connection you have to configure the settings in router like encryption, MAC address filter, etc.
For testing I would disable all these security features.
Last but not least you should check the TCP/IP configuration of your WLAN card. Maybe you need a static IP address or DHCP Depending on your router ;)

Re: Satellite U400-11Q with Vista has new HDD but no recovery disk

Hi,
Before I start a very important message: I usually don't work with pc...:-) At my work we have an IT-department for our PC's :-))
However, now I have to work privately with a PC/ notebook and I need help: I am sitting in front of a Toshiba Satellite U400-11Q with a completely newly formatted HDD and unfortunately with NO recovery CD or DVD whatsoever !!
So far I have managed to format the HDD aagain and to put a WindowsVista Home Basic (OEM Software) from my old pc onto this notebook. However, nothing works yet ( I want to get into the Internet etc.)
Therefore I now need to put on all relevant drivers as well as the original TOSHIBA drivers, right ?
How do I do this ? Which drivers to I need ? Do I need to download all relevant drivers (totally 113) one by one from the Toshiba website ?
ANY help is appreciated as I can see myself spending the whole night in front of this PC..
Thanks,
M

Hi Dr.Lamp,
thanks for helping me with listing the drivers as well as giving me a recommendation on the use of Windows 7.
Re Windows 7, unfortunately I only have a "free" VISTA Home Basic at home and therefore I have used this operating system for tonight ! I want to get this PC/ machine running as well as possible as quickly as possible...just unfortunate that its a PC with the need of "thousands of drivers"...
If anyone in cyberspace is interested in reading about my HUGE problems with simply setting up a computer newly, I can at this point simply recommend to you PC fanatics:
Please do put onto the internet decent driver packages to download for somebody like me in a bulk !!! why make life so difficult ? How the hell will I get the right order of driver packages ( which you are listing) on to this PC if I have:
- no idea where to find the drivers you mention ( I have to google every single one of them)
- I have already bought a "recovery DVD from Toshiba, but which takes up to 14 days to arrive and costs about 36 EUR
- I just want to get the computer up and running properly with all licenses legally acquired !
So here I am after about 12 hours of woring on this thing as a newbe:
I have so far this evening managed to firstly install a network driver ( I also had an old VISTA resource DVD at hand) after somehow installing some "recommended network drivers" ( by this recovery DD).
This way I managed to get the wireless LAN connection up and running which is a huge success, because I can now download drivers form INTERNET directly onto the computer.
Currently there is an installation running of Windows VISTA including about 120 updates for this VISTA, so I am busy on these updates...I am nowhere close to the 50% installed mark so I probably will have to get some sleep now and continue tomorrow with you list as well as finding your drivers and installing them in the right order ! What a drag ?! Well, somehow these PC's just cost you TONS of TIME..
Anyway thanks for you help and if you can give me a hint on a shortcut, I would be very happy to hear about it.
Thanks

Satellite U400 BIOS 4.0 doesn't work - error 120

Hello to All.
I tried updating my u400 with the newest 4.0 BIOS, and WinPhlash says BIOS is incompatible with current system BIOS + New BIOS part number doesn't match system bios part number. Error 120.
It says i should refer to the Help, but there is no .hlp to open...
I know I downloaded the proper file, i've flashed BIOS previously, i now have version 3.7
Anyone know how to solve this issue / had the same issue?
Tamás Lengyel

What is the exact model number of your Satellite U400?
I have checked the Toshiba website and I can find different model numbers of Satellite U400 so I think not every BIOS is compatible with every U400.
So check the Toshiba website again and choose your model on the list:
