USB port failure on Satellite P300-172

I purchased this laptop in August 2008, I have had no problem with it until last week when the USB port that I plug the mouse in to stopped working.
I changed to the next one, this also wasnt working, but one on the other side worked ok. Used the laptop all that evening, next day it would not boot up, just got a set up screen ,exited that and it switched itself off, switched on again, power lights all came on, but just a blank screen. I noticed that the area round the defective USB s got really hot in a couple of minutes.
I feel the USB failure has caused some major fault, motherboard perhaps.
I paid a lot of money for this laptop and I expected it to last longer than 13 months. I tried phoning Toshiba but I cant get through, it keeps saying press this button for the dept you want but whatever button you press it comes back to the original message.
Asked a computer engineer if he had any idea what could be the problem with the laptop and he thinks that too much power is going in to it.
Has anyone got any idea what could be the cause of that, I am housebound and rely on the internet.

Hi
Its pity to hear that your notebook started to malfunction but a hardware malfunction can always happen. Generally you should contact the ASP (authorized service partner) in your country for a help.
I dont know where you are from but I found this ASP database on the Toshiba European page:
http://eu.computers.toshiba-europe.com -> Support & Download -> Find an Authorized Service Provider
Regarding your issue;
In most case the higher internal temperature could be the reason for such shut downs.
The notebook supports some sensors which would power off the notebook to prevent the hardware from damage the temperature can increase because the cooling modules are clogged due to the dust and debris furthermore a usage of non-Toshiba graphic card driver can lead to graphic card issues So its always advisable to use the Toshiba graphic drivers.
Anyway it looks like your notebook needs an help from a expert so get in contact with ASP in your country and ask for details.

How can I connect my iPad to a TV that only has an s-video input available but also has a usb port on the satellite box available.

I would like to connect my iPad to my older TV but the only inputs available are the s-video input port on the TV itself and there is also a USB input port on the satellite box that feeds the TV. I could also split all the RCA jacks to accomodate another input here. Thanks in advance for any and all help with this problem of mine..............RR.

There is no s-video cable available for any iPad.
The USB port on the cable box is for maintenance use only.
There are RCA cables available:

USB port issue on Satellite Pro A300-13Y

I have a Satellite Pro A300-13Y with 4 USB ports. The two right side USB ports dont work. I have bought this laptop recently (2-3 weeks ago). It has a Windows Vista Business SP1 on it. I have Chip set utility installed on it, I have checked the device manager and I have tried to find driver for this but I couldnt solve this.
Then I called Toshiba service dek, they say I have to install again to factory standard install to see if it might be solved. But I dont find it the best way and I have some applications installed on it and have some info on my laptop so, I would like to find another way to solve this problem.
Also I think it could be a hardware issue. Can somebody show the way how can I find or solve this problem? I can also send it to guaranty, but if I made a mistake and if there is not a hardware issue I have to pay for this.

Thanks for your post. I will try it next week because I have much value of data on it and they have to be transfred to an extern harddisk that I'll buy this or next week.
Only something to know, I see in device manager a lot of usb controllers liste (4 usb controller and 4 usb root hub) in the Universal Serial Bus controller, where two of them are usb2 enhanced host controller and the rest are usb universal host controller.
Does it mean that Vista has detected only two USB2 controlleres?

Shortened story: A135-S2246 upgraded to Win 7.
System acts funky, so I do "clean install" of 7.
Dreaded BIOS password issue arises, but I get past it.
Like a good soldier, I upgrade the BIOS to 1.60 and install all of the Toshiba software for Win 7 clean installs.
The USB ports now tell me that every USB device I own is defective.
I've uninstalled all USB ports, drivers, etc., installed all drivers for my USB devices and tried to get Win 7 to manually recognize.
I've Google until my Googler is worn out and can't find a real fix.
NO LOVE.
Before I order restore discs (FREE! with a cost of $24.95 to mail them to me), can anyone tell me if this is issue is resolvable?

Satellite A135-S2246
I've uninstalled all USB ports, drivers, etc..
A good start.
Try disabling Selective Suspend. Open registry editor (regedit.exe) and navigate to the following key.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\usb
In this key, create a new DWORD value called DisableSelectiveSuspend and set its data to 1.
Reboot.

USB port failure

I have 2 USB ports on my Powerbook G4 laptop but one has mysteriously stopped working after installing Palm desktop software. I removed the software but the 1 port still doesn't work. I don't have my original startup disc anymore either. Any ideas?

Hi, thashiznit48. If you need to use two USB ports at the same time, working around the bad port by buying a USB hub (preferably an externally powered one) will be a whole lot less trouble and expense than replacing your Powerbook's logic board, which is the other main alternative.

N8 USB port failure

The USB port on my N8 has stopped working after about a month. When I plug it into my pc it doesn't register as a device and it doesn't charge from the USB port. Any suggestions? Or is it back to the phone shop?

No fluff in port. Tried to connect mass storage device but Nokia adaptor cable CA-157 brings up error report on phone. Heard bad reports about apps like OVI store being deleted and not being able to be reinstalled after 4 button reset. Red led does not light when any cable is connected.

Folio 9470m usb port failures

Has anyone else using this laptop model experienced issues with console cable connections? I am finding that a serial console session to a given appliance that I am configuring might last me one minute if I'm lucky, or might freeze after a few seconds. The only way I have found to address this is to reboot my laptop. This is really not ideal when i am stuck in a freezing cold datacentre and am working to time constraints. Plugging in the power helps (but not always) though this is far from ideal - what is the point of having a laptop that you can carry into a datacentre if it needs to be plugged into a power source before it works properly?! Any advice would be hugely appreciated.

Hello LadyBeader,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More. I understand that half of the USB ports on your computer are not responsive to USB devices, and I would be happy to guide you towards a resolution! To begin, I will need to ask you a few questions:
What is the Product and Model Number of your desktop computer?
What version of Windows do you have installed on your computer?
Has your computer completed all of its important Windows Updates?
Have you updated your HP drivers using the HP Support Assistant?
Is this an on-going, or recent issue?

Cannot use Touch keys on Satellite P300-172

Hi,
so I was cleaning my Toshiba laptop last week and after accidentally going over the touch keys it booted my computer up, I thought nothing of it because its happened before but for some reason the buttons have now broke and are no longer responding to touch and so they are now constantly on, this is annoying on numerous levels, 1 been that it drains on the battery a lot, the light it puts off at night is very annoying, and most of all I cant turn it off cos they wont work, as a result I can no longer use the touch keys
If any1 knows how to fix this please post a reply
Thank you

tnx but that didnt work, instead i took the AC out, ran the battery dead, removed battery, re-inserted it, plugged AC back in ,started it up n they all seem to work again now :)
tnx again anyways

Satellite P300-172 - What is my serial number

I'm trying to download easy cap software from a cd.
The install process requires me to divulge my laptops serial number.
Problem is I cannot proceed without inputting 19 digits whereas my serial number only has 9.
Is there something I'm missing here?
Please help.
Thanks

Is "easy cap" screen capture software or the hardware to capture video? If the latter then [http://forum.easycap.co.uk] . In either case I doubt that either software house has a list of laptop serial number formats and any 19 digits will do. But is your problem with a video capture package such as Ulead and your software was supplied as an OEM bundle with a different manufacturer's PC?

Satellite P300 - Multimedia Board not lighting up

Hi All
I have a Satellite P300-172 and the Multimedia Buttons above the keyboard dont light up/work anymore after motherboard replacement. The first time I switched the laptop on I had left the cable unplugged, it's plugged in securely now and they still dont work.
I have tried doing a hard reset, uninstalling/reinstalling VAP and updating the BIOS.
Any other suggestions to try?
Cheers

Hi,
I did replace it myself, but I'm reasonably well versed in laptop repair.
There's only one cable that runs from the multimedia button board and that's the one connected to the mobo, I've plugged it in a couple of times with no luck. I did a quick sweep of the other cables anyway, but they seem to be fine. (everything else works as well)
There is an Illumination Setting in the BIOS, switching it off turns the power and touchpad illuminations off, but when you turn it back on the Multimedia buttons dont come back on :(

USB Ports on 3 month old Satellite C655-S5049 do not work-even after Recovery to "Out-of-Box" state

Hello - Hoping someone can help with another suggestion- it doesn't look good.
Both USB ports on my wife's 3 month old Satellite C655-S5049 are non-functional with any USB device. Flash drives, wireless mouse, and external hard drive (powered) that all work on all of my other computers, do not work in either of this laptop's USB ports.
This problem seems to have developed gradually, and became noticeable previously as non-responsiveness in the wireless mouse, which gradually became a concern, with the computer appearing to freeze or lock-up - probably because of the number of times the mouse was clicked on shortcuts and executables before something happened.
The ports are now completely "dead"- no recognition of anything inserted once the computer is up and running.
There appears to be a thermal component involved, since I was able to get the devices recognized and working for up to a minute when booting the computer with the devices in the ports after it had been off for several hours after I did the default state recovery. The flash drive and mouse were recognized, drivers loaded message, but they then went to "unplugged" before I could get the cursor moving. I was able to access the flash drive, since I did it as soon as the driver loaded, but then it disappeared ("un-plugged" itself in the driver loaded message box). I can also get them recognized from this COLD boot state when I immediately plug them in once Windows 7 (64) loads, but they quickly disappear. If I wait a few minutes before re-booting, they flash during the Windows boot, but drop-out before it completes. If I wait 3-4 hours to re-boot, they flash (are recognized) for about a minute (Windows completely loads), but then they drop out.
I tried all of the suggestions on this board (and others) before doing a Recovery to Factory Default state. I have tried it with the original version 1.20 Bios, and with the version 1.50 Bios update. All driver updates have been downloaded and installed. The laptop does occasionally lock-up at the Toshiba screen during boot, and is verrrry slow in some operations (2 hours to do the recovery discs). The only other noticeable problem (at this time) is an occasional drop-out of wireless (Atheros AR9285) connectivity, which I have been blaming on the router since it is sporadic and infrequent (not consistent with the thermal argument). These problems are all after the Factory Default State recovery operation, so my assumption is that they are hardware based.
Any suggestions for a solution? This is a standard spec Satellite C655-S5049 that I was considering adding another 2GB memory to, but now I am unsure of its' future. A laptop cooler that runs from a USB port seems counter-productive.
I am technically capable, so you can be much briefer in your response than I have been in trying to fully detail the problems. This isn't the NVidia chip, but it does bring back memories of laptops past.
Thanks for any help,
G

No Audio or USB Ports after Recovery on Satellite L505D-S5983

I have recently done a system recovery with disks I created when I originally got my Satellite L505D-S5983. Which put the laptop back to an "out of the box" state...supposedly... I have been asking on a Microsoft forum for help with my problems, with limited luck.... It is still not working. I'm pasting my original posts here hoping that maybe somebody on here can help me.
POST 1:
My Toshiba Satellite L505D is running 32-bit Windows 7 Home Premium. After about 4 months of downtime I recently started it back up. There were roughly 37 updates to install when I turned it on, as expected. The updates were downloaded and installed, but when the system was restarted the system froze as soon as the desktop loaded. I booted multiple times and every time it completely freezes immediately after start up. I am not even able to open the task manager (ctrl+alt+del). They system boots perfectly fine in safe mode, and I ran what diagnostics I could find and nothing shows up....according to Windows everything is fine.
After Going through this multiple times, I got sick of it and decided to do a system recovery. Not a system RESTORE...it was a system RECOVERY. The HDD was completely wiped, and the system was supposedly returned to its original form as it was out of the box. Getting my hopes up as it finished its process... The system worked fine through the initial setup (language, time, etc.) and then as soon as the desktop loaded it froze again!
So here I am with a completely wiped HDD (except for the factory toshiba software), and a Windows OS that will only work in safe mode... I would like to avoid reinstalling Windows, I don't have any disks or anything. So any help would be appreciated
P.S. let me elaborate on what I mean by "froze". The system is completely non-responsive. No cursor movement at all, touchpad, keyboard, USB ports, nothing. When I did the restore the cursor, touchpad and keyboard worked through the initial settings only. Even when the desktop is loading i get movement for a second or two before everything freezes.
REPLY I RECIEVED:
Hi,
Since the computer is working in safe mode, I would suggest you to start the computer in clean boot to check which third party program is causing the issue. To configure your computer to clean boot follow the link
http://support.microsoft.com/kb/929135
Note: After you have finished troubleshooting, follow step 7 in the article to boot to normal startup.
If the issue does not persist in clean boot then refer ‘Step 3’, ‘step 4’ and ‘step 5’ from the following link to narrow done the issue and find out which service or startup item is causing the issue.
MY RESPONSE POSTING MY CURRENT ISSUE:
Thank you, and yes that's exactly what it was. It turned out to be an ATI program for my AMD graphics card that was not installed properly. It makes me wonder if I had to do the recovery in the first place lol.
However now I have a whole other issue. Windows is now telling me that "No audio output device is installed".....
In device manager the yellow "!" is there (High Definition Audio Controller), it tells me that it is not working....yet it says that the best drivers are installed! So yeah...I have no audio now. The only info windows gives me for the sound card is that it from Microsoft... with a driver version of 6.1.7601.17514....which naturally doesn't really help me since I have no idea what card or mobo I have . Is there any way for me to find out what I need other than opening up my laptop?

Ok...so I have installed all of the appropriate drivers that I thought I may need from this website. I have tried ALL of those system analysis programs that were suggested. Every one of them lists my mobo simply as a Toshiba motherboard, with no audio card information. Which I'm assuming that is because it has an internal sound processor. My problem is that none of the properties, or ANYTHING I try, will give me information on what I need to fix this...
I would be more than willing to run the recovery again if I knew that I had everything I actually need... When I created my original recovery disks it created a third disk with "apps and drivers". I installed all of them...and still here I am... And I haven't even STARTED on my USB port issue yet...those don't work either, and they don't even show up in my Device Manager...sigh...
And please, a response that doesn't look like an automated response to try and sell software like the last one I recieved from the Microsoft forum would be appreciated
Thank you for your time, and apologies for the lengthy post, but I wanted to provide as much info as possible.

Satellite L505D-S5983
I would try another restore of the hard disk to its original out-of-the-box contents using Toshiba recovery media. Maybe something went wrong in the process. Make sure everything works before applying any updates and adding any hardware or software.
Then add things carefully, rebooting Windows and testing the USB and audio at each step.
Please note this.
The only info windows gives me for the sound card is that it from Microsoft... with a driver version of 6.1.7601.17514....which naturally doesn't really help me since I have no idea what card or mobo I have . Is there any way for me to find out what I need other than opening up my laptop?

USB device failures and need to re-update under Windows 7 / Satellite A505

I'm having a devil of a time trying to get access again to a set of devices which worked fine under Vista-32 and backward..
Recent self-repaired problem, The laptop refused to accept a Garmin eTrex GPS via any other USB port except port 1 (the top-left port).. Attempts to attach it via ports 2 or 3, resulted in failure to read device, and Windows Device Manager reported the GPS asn an unknown device. The fix to get it to accept the device on these ports, required uninstalling the driver to those two ports (plugging the device into either of those ports, when seen by Device manager, uninstall the device, unplug it, the plug it back in again.) result now, all 3 ports will now accept the gps.
Now, an old device failure.. I have 3 different Prolific USB to Serial (rs-232C) adaptor cords, for connecting to older serial devicees. (older GPS's, external older computers, robotics projects, etc.) as of yet, the above remove/replace method will not allow connection of these cables (yes, using the supplied drivers, and a few generic found online from Prolific themselves) and, likewise refuse to access the devices connected to them.
There is one other device, which uses another form of USB to serial (FTDI Chip, device is the Arduino microcontroller, which uses the FTDI D2xx chip to connect via USB) I'm surprised, is actualy in the installed Windows-7 driver library, as well as a Microchip PIC18C745 (Vellaman P8055 project board) (also native device under Windows-7)
I've tried to find a reliable Prolific driver, but as of yet, these devices (Including one used in Microsoft's labeled version of the Pharos GPS500 dongle, which is sold with Microsoft Streets & Trips 2009 (The driver for this one, on other computers has caused system crashes.. Even under Vista & XP)
Is this a problem with the laptop itself, or Windows-7 that I'm fighting?

Toshiba Satellite C55-B5201 with Windows 8.1 64bit No USB Ports Work

I have had nothing but problems with USB ports on this laptop. I went from 3 USB ports all working fine, then 2, 1, and now none. Tried all the obvious from chipset drivers, restore points, even did a factory reset. The USB ports do not function regardless of whether I plug a mouse, printer, anything, into them. I have manually downloaded drivers, ran autodetects, and the OS acts like everything is fine. I find it hard to believe that all three ports have failed and believe it is either a windows or intel problem, but I dont know what else to try. Very frustrating since latop only 1 year old. Can anyone provide an answer to correct this problem. Thanks!

even did a factory reset.
That confirms no software on the hard drive is responsible.
