Satellite Pro L40: black screen but faint image in the background

Satellite Pro L40-17H (PSL4BE-00T005EN)
Hello,
I would appreciate some help with the following problem:
SYMPTOMS: Screen is black, but I can see that there is a faint image in the background.
I get a good image in external monitor.
I suspect, _among others_, that there may be a faulty *lid sensor/switch*, but I have been unable to locate it, although I have disassembled the unit.
If somebody knows, please let me have the exact *location* where I should look for the switch.
Thank you

Thank you RandyRoberts
You are probably right, it is likely that the inverter is faulty, or it might be a bad lamp.
Nevertheless, I cannot exclude the possibility that there is a bad or stuck lid switch. That is why I insist to check that one out as well.
I would still like to know where the lid switch is located on the L40.
Thanks and regards.

Satellite Pro L300 - Black screen flashing cursor

Hi all,
I have a Toshiba Satellite Pro L300 laptop running Vista.
The client brought it in because when it boots it goes to Toshiba splash screen then goes to black screen with flashing cursor in left top corner. I have connected external monitor with same result. Swapped out RAM as well.
Have run Memtest (passed), Seagate HDD long test (passed), Ultimate boot CD, and Winternals with no success.
*F8 does not work* and nor does Factory recovery.
Can get into BIOS F2 and F12 no problem and the HDD is listed there.
I reinstalled Vista from CD and when rebooted it goes back to flashing cursor. I have attempted Startup repair from Vista CD and System restore. FixBoot from Command Prompt and FixMbr as well with the same result.
I have a feeling it may be a corrupted CMOS? It is like the OS installs properly, but the computer loses it's memory on reboot of where the OS is located?
Is the CMOS battery easily accessible and removable on this model?
Has anyone encountered these symptoms? Is it fixable cheaply?

Hello
If you have clients I presume you are some technician and hope you have some hardware parts in your store.
Have you tried to set BIOS to default settings and check it again?
If possible try to exchange HDD and test the functionality again.
Can you use notebook with Linux live CD (HDD not needed)?
To be honest I dont think problem is BIOS and, in my opinion, CMOS battery exchange is not necessary.
Test it please with new HDD and post some feedback.

Satellite A300-Y00 black screen but fan starting

I bought a TOSHIBA satellite A300/Y00 in June 2008, i.e. 16 months ago. Model number PSAGOA-02Y. After ten months it suddenly did not boot. It sounds like the CPU and the fan is starting but the screen and the led below the screen were all black. I tried to connect it to an external monitor but that screen was black too. I gave it to Toshiba for 2 weeks (!) who said it was the motherboard. They replaced it for free as it was still under warranty.
A few weeks ago the same thing happened again. I turned it off and for some random reason it started as usual a few hours later. I called Toshiba to say that I think the computer will crash soon again. They said they could take it in for service but if they could not find anything wrong with it they would charge me x dollars. I did not give it in for service. I even went to a local Toshiba support guy who said he could not find anything wrong with my computer and that there was nothing he could do.
Now the same thing is happening again. This time I can't get it to start again. Of course their fantastic 3 months warranty for the last motherboard has expired. I tried to take out the battery and start it only on power but it does not help.
I don't want to pay $500 for a new motherboard and then have it breaking down again. It is obvious it is a hardware problem and I think Toshiba should replace my computer without charges.
Anyone with similar problems? Any advice? Getting pretty annoyed....

Hello!
Have you already contacted the authorized service provider again? If not, do it please! You should speak with the technicians again and then you will see what they can do for you.
I can understand you that this is annoyed but such things can happen and I think the ASP will do the best to help you. To be honest I have good experience with my ASP. The repair goes very fast and the technicians are very friendly and competent. Its always nice to talk with them a little bit.
Im not a technician but maybe they can repair it as a gesture of goodwill or you have only to pay the mainboard and not the exchange

Satellite Pro L40 PSL43E I need to find all the XP drivers

I need to find all the XP Drivers for this particular notebook. Any ideas where i can find them. on this site i only get the "how to downgrade" Pease Help ASAP

If such drivers are available then you will be able to find such drivers on the Toshiba European driver page.
If the drivers are not available on the Toshiba European driver page, then the drivers were not released.
But Ive got one hint; I found some XP drivers for Sat L40 series. Some series supports the same devices and therefore the drivers should run too.
Check some single XP drivers from different L40 series and maybe it would run.
Ciao

Satellite Pro L40 wont boot after changing BIOS settings

Alright changed a few settings in the bios last night and now when I boot I get a black screen lights flash and that hard drive light comes on but nothing on screen.
There was no password on bios,... how would I reset BIOS to normal?
I put a windows disk on I can hear the disk spinning but nothing on the screen
(I think I have come to the right place on the forum)
Its a Toshiba Satellite Pro L40 model psl4be.
Thanks

>There was no password on bios,... how would I reset BIOS to normal?
You can set the BIOS to default ONLY inside the BIOS so you have to access the BIOS pressing F2 or at the beginning of the booting order
But I doubt that this problem is related to the BIOS.
Maybe its just a simple bad luck that this issue happened just exactly after changing something in BIOS.
Try to connect an external monitor and check if you can see something on 2nd display.

Satellite Pro L40 wont start

When i turn on my Satellite Pro L40 it shows me a screen asking me to start windows repair or start windows normally.
When choosing either option it leads me back to the same screen.
Does anybody have any ideas?
Many thanks

Hi Will
For me it looks like the installed OS was muddled up for non apparent reason
If you are not able to boot in the Windows XP OS and if the repair option doesnt help to boot in the safe mode I dont see any other possibility as to boot from the Toshiba recovery CD and to reinstall the operating system again!
But note; the booting from the recovery CD will format the whole HDD and you will lose all files stored on the HDD. ?
This is a drastic procedure but in my eyes its the only one which could helps to solve this issue.

Memory upgrade on Satellite Pro L40-15d

Hi
I have Satellite Pro L40-15d with 512 memory (Samsung) but I wont upgrade to 1GB. I have Kingston ktt667d2/1g I have tray to put in to both slots but nothing work I cant switch on computer.
But when I change for old one laptop is ok. What can I do? Install special program or update BIOS or maybe the memory stick is broken.
Regards

Hi
The notebook doesnt boot after the memory upgrade due to these different issues;
- memory modules are not compatible together
- memory modules are not compatible with the notebook
- memory modules are faulty
- one of memory slots is faulty
In most case the memory module replacement helps.
One hint; did you try to switch the memory modules in the slots? Sometimes this helps.
Several weeks ago I have updated my memory and the notebook didnt boot.
I thought its a memory malfunction but after module switching the notebook booted correctly.
Good luck

My mbp always hang (black screen but still keyboard light)(snow leopard and lion) and self hang and restart(mountain lion), How can I do? (I report problem to apple for 100 times but no reply)

I use mbp late 2010 (MacBook Pro (15-inch, Mid 2010) Serial Number: W802627ZAGZ)
(core i7 2.66GHz. 15" 4GB 1067 MHz DDR3) and change display to highres (1920x1080)
it has problem that the screen go blank (or black screen) but keyboard still light. seems to display driver stop working.
I send my mbp to service but they said no problem about hdd.??? I'm not sure that they take care just only hd problem but not handle another problem that I tell him.
I use it and it still hang up (not it reach 100 times errors) how can I do with this problem?

Can't recall which I used to do the dynamic repartitioning.
I'm betting that it was originally Partitioned with Snow Leopard.
As a test I just added a second Partition with Mountain Lion to a FireWire HD and it would not let me Install Snow Leopard from my System or Retail Disc into the Partition.

Satellite Pro L40 - What is a average battery runtime?

Hi there,
I just recently received my Satellite Pro L40 and am just wondering what the average battery runtime is? Once fully charged it only seems to be able to handle 1hour max. Is this normal?
The laptop I had before was the same, but my friends laptop, which is more than a year older than mine, runs for more than 3 hours on a fully charged battery.
Is there a fault??
Thanks

Hi
It is not easy to answer this question because the battery working time depends from the notebook usage. You should know that you will be able to run the notebook much longer on battery power using only some common applications like Word or Internet Explorer.
Playing games, watching DVDs or burning the CD/DVD waste more battery power because the performance of the single devices is much higher!!!!
Fact is that the Pro L40 notebook was equipped with high-tech parts and devices. The notebook supports a strong Intel Pentium Dual-Core CPU, huge HDD, nice GPU and and and
Furthermore you should know that the preinstalled Vista OS eats many resources and waste more battery power as the Win XP!!!
All this factors has a influence on the battery working time.
Last but not least you should know that there are different batteries on the market.
If you want to increase the battery performance buy a stronger battery!!!

After an iPad update yesterday I sent a video and it is not viewable just black screen but sound is there. I sent it to my windows 7 laptop and there it is not viewable at all the start button appears crossed through.only works on apple PC

After yesterday's update sent a personal video it was not not viewable , i was told only black screen but audio, will play on apple pc but not windows.
On my own windows operated laptop when l open the video the start button is crossed through
Is there something l need to do? I can view the videos fine on my iPad ?

'The installer has insufficient privileges to modify this file C:\Program Files (x86)\Common Files\Apple\Apple Application Support\Web kit.resources\inspector\Images\Spinner Inactive Selected.gif.'
That one's consistent with disk/file damage. The first thing I'd try with that is running a disk check (chkdsk) over your C drive.
XP instructions in the following document: How to perform disk error checking in Windows XP
Vista instructions in the following document: Check your hard disk for errors
Windows 7 instructions in the following document: How to use CHKDSK (Check Disk)
Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors, or use chkdsk /r (depending on which way you decide to go about doing this). You'll almost certainly have to schedule the chkdsk to run on startup. The scan should take quite a while ... if it quits after a few minutes or seconds, something's interfering with the scan.
Does the chkdsk find/repair any damage? If so, can you get an install to go through properly afterwards?

Satellite Pro L40 - Sound Driver after Windows XP SP3 Install

Hi,
I had bought the Satellite Pro L40 about 6 months ago and the speed of the laptop was too slow with windows Vista. So I decided to install an old copy of windows XP that I had bought earlier. I upgraded the windows installation to SP3 before installing all the drivers.
Now all the drivers have been installed properly except the sound driver. I downloaded the XP version of the driver from the toshiba website but it did not work. So I though maybe the vista version would work, so I downloaded that. But that didn't work either.
Can anyone suggest a solution where I can get the sound driver to work? Preferably without having to get the windows reinstalled again.
Please help me out...!
Thanks

Mac Pro intermediate black screen at boot after installing mountain lion

I have a 2008 Mac Pro tower, but since installing Mountain Lion I now get a random black screen at boot. Unplugging the apple cinema 20' power supply for 15 minutes seems to clear the fault. Have had no such problems with other OS until Mountain Lion, seems OK when booting to Snow Lepoard on my other drive?
Anyone have the same fault?

Thanks for trying the help! I tried every version of start up, but with no screen it was no good..
Finally solved the problem, it was the ATI HD 2600 XT graphics card that was dying a very slow death.
Replaced it this morning with a GT120 Nvidia.
Anyone with this card should Google it, as apple did a big recall on these..

Can I upgrade the T2310 CPU in Satellite Pro L40-15D series laptop?

Hi, ( I apologise if this has been asked before but when I search ' Satellite pro l40 series' I found no relevant answers )
I've been searching around the net & so far found some conflicting answers to this question so hopefully this forum may be able to help.
I have a Satellite pro L40 15D laptop and I wish to upgrade the Intel Pentium Dual-Core 1.46 Ghz T2310 CPU to a Intel Pentium Dual-Core T4300 2.1GHz 1MB 800 CPU or something similar.
I have found the following information from http://www.notebookcheck.net/Review-Toshiba-Satellite-L40-14N-Notebook.7294.0.html
" f you consider a CPU upgrade, there are not many options available. The Intel GL960 express notebook chip set supports only up to 533 Mhz FSB processors. So, most of the up-to-date Core 2 Duo CPUs (with 667MHz) cannot be used. "
But then I have also read that the GL960 can run processors of 800Mhz?.
I also asked the question on ebay from the seller of the T2310 CPU & received this answer
"SHOULD be okay, but your T2310 has 533Mhz FSB and the T4300 has 800Mhz.
Most modern intel motherboards should easily accept an 800mhz cpu, but I cannot guarantee. Might be an idea to see if you can find out if there are other models of Toshiba L40 that also have 800mhz chips, as that would be a good indicator.
And if I can not upgrade too a T2310 because of the 800mhz is their a 533mhz cpu that will be compatible & more powerful for audio production than my current 1.46 Ghz T2310 CPU.
I have only had this PC 4 years from new,it would seem to me to be not very resource friendly if this laptop has not be designed to handle upgrades.
Thanks for any guidance.

'Problem is that CPU upgrade is not supported and all you do is on your own risk.
Check also http://aps2.toshiba-tro.de/kb0/TSB9401AX0001R01.htm"
Helpful link thanks :-)
Of course any upgrade I did personally would be entirely at my own risk .
So it's not a good idea as mentioned .
I would still like to know if technically it is possible and if so it's most probably been done & maybe works fine, rather then half answers .

Alternatively do you guys have any suggestions, other than buying a new laptop, of ways to increase the performance for music production.
I already have 1.99 GB of ram installed .
Would using a external USB sound card and bypassing the internal sound card give me a little more processing power . I believe it's the real time processing of audio effects etc that make audio production demanding on a cpu.Could that processing somehow be shared with a pro audio card? .
Either way thanks for the help guys :-)

BIOS update issue on Satellite Pro L40-15A - Old BIOS can't recognise EEPROM

Hi
I'm having trouble flashing my bios.
I have a Satellite Pro L40-15A.
The Toshiba winflash tool that comes with the bios file tells me that the 'Old BIOS can't recognise EEPROM'
I was recommended to use AFUDOS on another forum but that tells me the bios has an invalid boot block.
AMI flas for dos tells me the flash rom is write-protected??? There is no option in bios to disable it and I don't think anyone would be dumb enough to put a hardware Bios protect jumper on a laptop.
Please help
Thx

Hi and thanks for reply
The 5.10 bios update is only for XP laptops, my one came with windows vista installed so I need v2.20
"old BIOS cannot recognise EEPROM" is the error message i get when i try to flash the bios with the supplied software from Toshiba
_+UPDATE:+_
New verion of BIOS update has worked!!
Case could be closed
