Satellite Pro L20 - typed keys missing

We have about 20 laptops, Satellite PRO L20 (model No. PSL2YE-00H00EG3), and all have this problem): keyboard missing from time to time a key is pressed. All keys are affected and the question is very worrying, given that you can have a miss every 20 letters typed.

We have tried to update the BIOS to version 1.5 to version 1.8, but we had no success.

Any help would be appreciated.
Thank you
Bogdan

Hello

You said that this problem occurs from time to time. In this case, it would be possible that some 3rd applications have a bad influence on this keyboard as described in this announcement.

You also suggested that you tried to upgrade the BIOS. Did you, or was it just a tent?

    Hello

    I have a satellite Pro L20 running xp pro. We use at the school, connected to a projector to display on the screen for children to see.

    the problem is that we use the Fn + F5 key on the laptop to scroll the screen option (two screens or not) but nothing happens, it seems that it does not meet our request. and the projector read no source found. Some days she turns on automatically, but when it doesn't. We are stuck, I tried to look into the display properties, but nothing here to try n force both screens light up. Help

    Hello

    Also try switching to the external device settings Intel. You can find it under Advanced display settings. I also recommend you to reinstall the TOSHIBA utilities. I'm not 100% sure but it may be responsible for the function FN + F5.

    Also check Toshiba HWSetup under the view tab. Activate LCD + analog RGB option.

  • Blocking number on Satellite Pro L20 problem

    We have about 60 Satellite Pro L20s on a network. When the user starts the computer sometimes they start with the number lock on. Its seems to be worse on some than others. It is very annoying because it causes problems with logon.

    Is it possible to disable the locking function of the number on these laptops?

    Thank you

    Mark

    Hello

    I'm a bit confused. I thought that MS L20 has no Num Lock key.
    Is it may be on a green light below the F11 key?

  • Need to reinstall windows, but does not have any CD - Satellite Pro L20

    Hi, I wanted to reinstall Windows XP home on my Satellite Pro L20, but do not have the software that my laptop came with (read the discs lost). I have a valid XP tone (like its stuck on the bottom of my laptop), but no disc so I tired using a copy of a cd of Windows XP home, which did not work, but let me go as far as the formatting of the hard drive.

    So now I use Ubuntu, but want to reinstall Windows. Have valid product key, but no software to reinstall.

    Any suggestions?

    Thank you

    Christopher

    Valid key will not help you. This key belongs to the image recovery and copy included WXP he.
    If you have two options. Either you order original Toshiba recovery image or use Microsoft installations CD key which belongs to this copy. All the necessary drivers, tools and utilities that you can download at Toshiba support page under http://eu.computers.toshiba-europe.com > support & downloads.

    Good luck!

  • Satellite Pro L20 - where to download the recovery disk?

    Hello

    The Toshiba recovery disc can t be downloaded. If you want a new drive, you must contact an authorized service provider. Maybe they can order a new one for you.

    Alternative you take Microsoft Windows disk and install the operating system for this disk. After that, you can download all the drivers and tools on the Toshiba site. It takes a little longer and it s not so uncomfortable.

  • Satellite Pro L20 - can I put it to Draft N?

    Can anyone of you thin people help me?

    Satellite Pro L20
    Centrino 1.8 GHz processor
    1 GB OF RAM
    Windows XP

    I have a Satellite Pro L20 who has a tiny inside wireless card, IE wireless b/g and I was wondering if I could replace it by a minié n wireless card.
    It is said in the literature that it should be a mini PCI type 111. Any help would be appreciated.

    Thank you all for your valuable time.

    I agree with Luke antenna WLan 802.11 N standard needs 3-wire WLan to be able to run with better performance. AFAIK the antenna WLan used in L20 has only 2 sons and this may affect the functionality of Draft N.

    I also recommend using a USB external Wlan key, which provides Draft N performance.

  • Satellite Pro L20 - disk hard keeps spinning down

    Hi, I have recently updated the BIOS on my Toshiba Satellite Pro L20, and I noticed that the disk hard keeps spinning down after about a minute, even while typing or surfing on the internet. I checked the power settings Windows XP and have it put on the desk, with the time 'Disable hard drive' set to 5 minutes when it is plugged and 5 minutes on battery (I always use on the same network). I checked the BIOS settings to see if there is something listed there, but there are no settings for hard disk power management in the BIOS.

    Although the turning down of the hard disk does not affect performance, I fear that it may be to focus on rising constant power drive / descent.
    The new version of BIOS is 25 April 06 Windows Bios Update for Satellite L20 (PSL2X), Satellite Pro L20 (PSL2Y) and Equium L20 (PSL2Z)', or a file 2, 20 - WIN.

    I think that it s nothing unusual that the HARD drive keeps spinning down applies none or BONES need the HARD disk activity.
    In addition, the turning down of the HARD drive has no effect from the bottom on the performance of the HARD disk or over the life of the HARD drive.

  • Satellite Pro L20 - overheating of the power cable

    Hello

    For several months, I had problems with the keys suddenly works intermittently. Although brushing under the keys with a toothbrush relieved the problem for awhile it obviously was not the main cause. Each time, so not attributable to each of the keys of damaged to different keys.

    When unplugging the power cable from the metal part is very hot, and I worked on the problem of keys occurs only when the computer is running on a/c AND the battery is fully charged. In other words, no problem on the battery or recharging. The adapter is also hot, but guess that's 'normal '.

    The power cable has been tested directly from another outlet and not ongoing execution of the usual belkin surge protector, external sources seem so plotted on. I tried to find another cable/adapter to test but living very rural location of doubt this will be possible or practical.

    The fan seems to work OK, the air coming out of the side is very hot. It does not appear to be clogged with dust. Also, the area of the laptop above the fan heats up.

    Sometimes the computer crashes on black or blue screen (on iplayer lately, maybe other progs too) but the noise continues. I turned off by pressing the button for 5 seconds, but he still works for a while. I guess from overheating. But not some of it is always on a/c-do not charge, it may be on a/c-charge as well.

    Sometimes the computer seems confused if he is re-load, on a/c or battery. At least the icon switches and requires a session to unplug the device before doing things.

    Other times it is the machine of Angel since last two years! It's a Satellite Pro L20, the adapter's clover LiteOn 65W, 19V 3. 42 a. part PA3396E-1ACA (what I see is no longer available).

    Searched through but not found any similar problem, but hope someone can advise me what to do next!
    Thanks in advance

    Hello Robin

    It doesn't sound good. According to the specifications of the laptop, you have the right AC adapter. In my opinion you should contact the partner of service authorized in your country. Make a call and I hope they can help you how to handle this issue.

    It is also possible that they can send you new power adapter. Make a call and explain the situation. If you have need for addresses and phone numbers you can find under http://eu.computers.toshiba-europe.com > support & downloads > find an ASP.

    Good luck!

  • Satellite Pro L20 - need keyboard driver

    Hello world

    Just need help to find a keyboard driver Toshiba Satellite Pro L20, I re-installed windows as my hard drive crashed and as was a second hand laptop he didn t come with recovery disks.
    I downloaded every other player wireless, screen, sound, touch pad batch but I really struggle to find a m keyboard driver.

    My laptop at the moment alone will keyboard type with the weird key, others do not work at all I use a plug to the keyboard for the time being, not very mobile.
    Any help would be appreciated most.

    Kind regards
    Dave

    Thank you to everyone who takes the time to read my problem.

    Akuma is right. You should not install driver for keyboard functionality. Used keyboard driver Microsoft standard included in the operating system Windows XP Home/Vista edition.
    So if some buttons do not work, there may be a problem with the keyboard itself and you need to replace.

  • Satellite Pro L20 - cd/dvd drive not responding

    Hello

    I currently have a Satellite Pro L20, recently my cd/dvd drive a work stoppage, and he comes back with the error message i/o device driver. It is impossible to read any form of cd/DVD. I can't explore keeps it the d: drive asking for a disc to be inserted.

    Thank you.

    I relly m not 100% sure if my advice will help you to solve this problem, but I recommend to remove the drive from the device and then Manager to delete the Upperfilters and Lowerfilters values completely from the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}

    Then restart the laptop and check if it helps it worth a try.

    Anyway if it doesn t help chances are readers equipment would malfunction. Maybe the s drive laser lens can not calibrate in the right position and, therefore, it of not possible to read or write CD or DVD.

  • Satellite Pro L20 would not publish.

    I received a Satellite Pro L20 who had probably overheated (was running with contribution covered and turns off for good).

    So far I had removed everything and mobo appears intact. I had allowed cmos and disconnected the battery, reinstall CPU (tested ot in a separate mobile - good) and I tried to start the internal/external screen with no effect. It starts well, fan turns and responds to the shortcut keys / deals with optical and hard drive but gives no video output. I can't test the ddr2 memory as the other laptop is ddr.

    Is there a way to test the video output somehow? F5 (with connected external monitor) several attempts but don't know if he responded to it at all. It responds to the reset / wireless, powers down and changes corresponding s LED but gives without being eps either. And Board of Directors has no led indicator. Powering with F12 does nothing. And there is a clicking noise when you start (with headphones).

    Any ideas would be very welcome.

    P.S. The profanity? At least mark what you think, it's blasphemy - spend 10 minutes to make it messy and get what abbriviation consider you profanity...

    You already have thougt that the motherboard could be defective? I mean the machine give some answers but it won´t come up anyway. It could be:

    -Defective RAM
    -overheaten CPU
    -some resistance or capacitor on the map
    -Perhaps that you have forgotten something or some metals inside the machine fold which causes some short circuit (there was already this case a few weeks ago here in the forum, the guy disassembled the machine again and discovered that some metal shielding of the base that was turn during reassembly of the laptop.) It caused a brief signs and come the didn t machine..)
    -a faulty device (such as HDD, modem, keyboard, mouse, and any other PCB) which translates the non bootable.

    Check the machine carefully (maybe it would be good to take it apart again), so if the machine after checking the won´t happen then you should give the machine to a toshiba technician. Maybe he knows better?

  • Driver LAN for Satellite Pro L20 Windows 2000

    I am looking for a local network (ethernet) drive to my Satellite Pro L20, who has Windows 2000 on it.
    I found one for WiFi, but not for the Ethernet (cable/CAT).

    Hello

    Well, you can t find all the LAN for Win2000 drivers on the Toshiba page because this unit has been delivered and tested with the Windows Xp operating system.
    However, I found the information that the appliance has a CL LAN Realtek 8100.
    In this case, I guess for visit the site Web of Realtek. You can find a compatible driver for this network adapter.

  • What recovery CD to use with Satellite Pro L20?

    We have several Toshiba laptops in use in our society. I need to restore a (a Satellite Pro L20) to factory settings. However, although I have kept all the recovery CD, most of them have labels which do not mention which model they are intended to be used on. On some of them I wrote the model number on the label by hand, but I did not do that for the L20. I know from experience that if I receive the wrong recovery CD, I have to put dozens of drivers and utilities individually, in order to find the right one would save me a lot of time and stress.

    Each recovery CD has a number (for example GMR400626EN1), so it should be possible to identify the good CD of it, but I can't find the info on the Toshiba web site.

    Is there a list that corresponds to the reference numbers for the models of laptop recovery CD?

    Hello

    This info is certainly not available on the Toshiba support site. What you can try is to contact the partner of service authorized in your country. They have access to the database of Toshiba and I'm sure they can help you.
