Satellite A300 cannot turn on when AC adaptor connected

Hi,
I have a problem with my Toshiba Satellite A300 when the notebook is connected to power adapter I have no possibility to turn it on, it goes only 2-3 sec. on an after it goes down.
When Toshiba is turned on with the battery supply and I tried to connect power adapter it goes also down.
I have no problems with charging itself but only with operating with power adapter.
Please help me what can I do with this issue, does anybody has similar problem?

Hi!
For me it sounds like a hardware malfunction of the mainboard if the AC/DC adaptor is connected and notebook is turned on
Im not sure but the best way would be if you go to the nearest authorized service provider with the AC/DC adaptor. The technicians can check your notebook and exchange the mainboard if its really necessary. The guys are very friendly and useful!
Here you can search for the nearest ASP:

Why do I get the message "cannot get mail" when trying to connect to microsoft exchange server.

Why do I get the message "cannot get mail" when trying to connect to ms exchange server?

Hard to say. Has it ever worked? Maybe your account has mobile e-mail disabled. Maybe ActiveSync isn't set up properly on the server. maybe the correct ports are not open on the corporate firewall.
You will have to talk to your IT department.

Satellite A300 - Not turning on, screen remains black

I have a Satellite A300 laptop. I tried turning it on when I got home from work and the monitor remained blank. The lights come on the bottom (the plug, the power and the battery lights) but the screen remains black.
Can someone help me?

Hi
Its difficult to say whats going wrong here but maybe its just a small issue which could be solved easily.
Try this;
Remove the battery, disconnect the AC adaptor.
Then wait some hours and plug the both parts again.
I had such issue in the past and leave the notebook disconnected during the night.
Next morning I plugged battery and A\c adaptor and the notebook worked again
Maybe this will help you too

Satellite A300 : cannot boot : blocked by Phoenix TrustedCore Setup Utility

This one is a bit bizarre. We have a Tosh Satellite A300-193 Laptop (Manufacturer Code: PSAJ1E-01000XEN) purchased July 2008, which my daughter uses for work. We have Kaspersky anti-virus on it, but since its license had expired (and we didn't really like it), I was going to remove it and install Avast.
Kasperky's removal instructions involve getting their "kavremove" tool which their instructions say should be run from safe mode. So, having downloaded the tool, I pressed F8 to boot to safe mode. ...
That's when things went wrong. Instead of the typical black boot-options screen, I got a password request from "Phoenix TrustedCore Setup Utility". We have never set up a password on this machine, and I have never seen this particular screen before. After three wrong guesses (!), the machine powers off.
Now when I turn it on, it goes straight to this Phoenix password request: I don't touch F2, F12, F8, or anything. I cannot work out why it should do this, nor how I can possibly by-pass it. None of my password guesses work (of course). My daughter is a primary school teacher with a school inspection looming in a week: while she has most of her work on a USB stick, there is data on this machine she really needs. Needless to say, tensions are rising.
I have googled all evening, so I know there is no point asking about passwords. But can anyone point me in a helpful direction? I'm baffled and at a loss. Grateful for any help (or hope!).
David.

Hi,
Which steps/procedure in that other thread you linked did you do to make it boot without asking for the BIOS password?
I looked through that message briefly, and what I didn't see is that after you get it to boot, you should probably go into the BIOS and reset the BIOS settings to default.
Another possibility is that the BIOS firmware itself may be corrupted, causing it to think that there's a BIOS password set. If that's the case, you may need to try to flash the BIOS with a known good BIOS, maybe booting from floppy or CD to do the BIOS flash.

Win7 on Satellite A300 - cannot get FN keys to work

Hi every body
I really need your help guys I really need FN keys job
I recently formatted my Satellite A300 laptop with Windows 7 32bit and the function keys doesnt work. I downloaded VAP from your site also I tried downloading flash card utility from the other Toshiba types list.
When I try to install it on my Toshiba it kept saying to me invalid serial no.
Why is that >> also still FN keys doesnt work. Please help me. What should I do?
Sometimes when I push FN+ brighten it works but nothing appears on my laptop as it used to when I had xp also I bought my Toshiba from UAE.

Hello
I have satellite A300 too and use it with Win7 32bit. Everything works perfectly. It is very important to install all drivers, tools and utilities following right installation order so here is the list how I have done this:
Satellite A300 (PSAG8E) and clean Win7
-Win7 (original Microsoft install disc)
-chipset driver
-storage manager
-display driver
-sound driver
-modem driver
-supervisor utility
-infrared
-patches
-configfree
-VAP
-toshiba hardware setup
-HDMI control
-WLAN driver
Everything works well but missing some drivers
Added Vista stuff:
-Toshiba assist - work properly
-Card reader - installed properly
-Webcam driver for A500 - tested with Skype - work properly.
-Synaptics driver
Win7 runs well and I am very satisfied with it.

Satellite A300 - Cannot install operating system

I just bought a notebook Satellite A300.
At the begining it had no operating system, but the one at the store installed me Windows 7 ultimate (trial).
Now i have problems installing other system.
It shows me an error and one more thing. When i bought the notebook it had no cd-s, no drivers, nothing, it is ok?
Please respond me, I don't know what to do.

Hallo Alexandra
I have the same notebook model and at first I want to say that you got good choice. Satellite A300 is supported for WXP, Vista and for newest Win7 too. I have tested performance with all three operating systems and to be honest, best performance is under Win7.
So I recommend you to install Win7. I can help you with exact, step-by-step guideline.
If you want to install WXP you MUST use WXP SP2 or WXP with SP3. Your notebook has SATA HDD inside and when WXP installation starts you must load SATA driver (F6 option when WXP installation starts). This SATA driver can be loaded with floppy disc. Other way you must create WXP installations CD with integrated SATA driver. For this purposes you can use nLite software. It can be a little bit complicated.
Using Win7 you don't need this SATA driver.
Please let me know your opinion about all this.
At the end I must say that you should maybe look forward and learn to use newest operating system and newest compatible software. We all like WXP but it is time to say goodbye. Do you agree with me?

Satellite A300 keeps turning on closing the lid

Hi all,
This is my first post here.
I have a Toshiba Satellite A300 laptop and every time i close the lid/screen the laptop turns it self on.
having narrowed it down to the media bar above the keyboard i found that if i turn off the laptop and then touch the media bar it turns on the laptop,
I have disconnected the ribbon cable and i can close the lid and everything is OK, as i thought it was the on/off switch at first.
any ideas?
Regards

Having looked at the bios there is no System Configuration -> Function Buttons (disable/enable)
I have tried the Toshiba Button utility but that's not working as the drop box "Name" is empty.

Cannot turn on ipod without USB connection

I bought my brand new ipod nano yesterday. I've added all my tunes, it's been charging all night, but when I unplug the nano (it says 'charged' apparantly), I cannot turn it on. While it is plugged into my USB, the nano is fine...I can listen to songs and scroll through the menu etc, but it just won't turn on if it's not plugged in
Maybe it's not fully charged? It says 'charged', but if I plug it in again to charge, it keeps on charging. Is there something wrong with my battery? Help me

Hey msakamoto,
Thanks for the question. I understand you are experiencing issues with your iPod nano. The following resource may help to resolve your issue:
iPod nano (6th generation): Hardware troubleshooting
http://support.apple.com/kb/TS3474
Will not turn on or screen remains dark
- Connect iPod to power for at least ten minutes to ensure that the battery has enough charge to allow iPod to turn on.
- If iPod does not turn on after ten minutes, try resetting the device while it is still connected to power. Reset the iPod by holding down the Sleep/Wake button and the Volume Down button for at least eight seconds or until you see the Apple logo appear.
- If the Apple logo appears on the display, connect iPod to a computer and verify that it appears in iTunes and can play music. If iPod appears in iTunes and can play music, no further troubleshooting is needed.
- If the screen remains dark and will not turn on, then your iPod may need service.
Thanks,
Matt M.

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 Pro A300 - Cursor constantly moves when external mouse connected

Hi there
I have a Satellite Pro A300. When I attach a mouse directly by USB the cursor is constantly moving. I also have a mouse attached via a Toshiba docking station and that works perfectly.
It doesn't matter which USB port I use or whether the laptop is connected to the docking station or not, or whether it is running on mains or battery power.
I thought it was the mouse that was the problem so I went and bought a new one but the problem is persisting.
Actually, while I have been writing this post, it has stopped doing it and then started again! Very frustrating.
Can anyone help?
Thanks
Susib

Hi
How about the touchpad does the cursor moves and jumps using the touchpad?
Try to disable the touchpad while using the USB mouse check if you can notice a difference
How about BIOS?
Do you have the latest version installed?
Check this!

Satellite C850-B820 turns off when I take off my power cable

Hello
I bought laptop Satellite C850-B820 2 months ago, usage on it normal, 2-3 hours daily, i was working on it without the power plugged in, the battery status was 50% so i plugged in to recharge, suddenly electricity went off and came back for 1 seconds, after a while i took of the power cable and suddenly it cut off, re plugged it again and checked the battery status its fully recharged 100%, anyone have idea what wrong with it?
Might the cut of electricity effected the battery or the mother board?

>Shows 100% recharged, but the battery has no action, if i unplug the cord it cut off,
In my opinion there are two possible reasons why the unit shuts OFF when the AC adaptor is disconnected.
1) the battery malfunctions and the battery charging status is wrong
2) the motherboard power supply electronic is faulty. Such electronic controls the notebooks power supply
I think you should check if new battery would helps to solve your problem.
But you said that the notebook is not very old, about 2 months old and therefore the warranty should be still valid.
In this case you should not try to resolve this yourself but should contact the service in your country in order to check the unit. It should be definitely warranty covered

Satellite Pro A120 cannot boot up when printer is connected

Hi I have a brand new Toshiba Satellite Pro A120 but am having a very strange problem.
I installed my printer - Epson Stylus Photo R300 but now the laptop wont boot up if the printer is turned on. When I turn it on the Toshiba screen comes up ok, then the Windows XP screen comes up with the black background when the blue bar goes across to load Windows but its all faded out and the laptop just freezes and will not power up!
However if you turn the printer off and re-start the laptop it boots up fine!
Its definitely the printer that is causing this as its only when I have it turned on.
It never caused this problem with my old PC that was using Windows XP too.
Any help with a resolution would be greatly appreicated.
Thanks
Adam.

Hello Adam
I am afraid there is not much to do. Friend of mine has the same problem and the fact is that Epson chipset is pretty bad and it gives completely wrong information to the system. Because of that notebook is confused and can not start.
I can just recommend you to use USB hub and I hope it will work. I dont know if your notebook can boot from USB device but if this option is available please disable it.
Good luck!

To be honest I dont understand your question
If you have formatted the second HDD this should not be a problem to start Windows.
Have you burned the recovery disk? Then boot from it and install the notebook.
