Equium A300D-16C. not booting after shutdown.

Please, this is a problem i seem not to understand. I have been using my Equium A300d-16c laptop without no problem for over a year until yesterday's evening. i was installing a software(nokia PC suite) which prompted for a restart. the shutting down was normal and for it to restart was a problem. it displays nothing but a blank screen. It is evident it does not boot as when i press the power button it goes of immediately. Only the power indicator is on. Another thing i notice is that the DVD-ROM reads any disc put inside but there is no display of any sort.
My first reaction was that it may be overheating, so i cleaned the cooling vents and blew away dusts from all compartments. but still the problem persists. Please i seek to know what may be the problem before taking it to for repairs. Help Needed. Thanks.

Thanks. There is nothing displayed on the screen. it does not seem to boot into anything, as the powere goes off immediately when the power button is pressed. I have tried to change the ram modules, but still the same problem. i dont know what kind of hardware failure could cause this as it was working fine untill the shutdown. Thanks for the concern.

Equium A300D will not boot.

My Equium A300D won't boot. It just displays that "file is possibly corrupt. File header checksum does not match the computed checksum". Why? What can I do? I only have it a few months.

Have you installed new RAM lately? Its important to test the RAM before using it. Or perhaps the standard RAM is faulty.
Go to www.memtest.org and run Memtest for a few passes (its a bootable CD).
The file system could be corrupted, try running CHKDSK from the Recovery Console. http://support.microsoft.com/kb/314058
The HDD could be faulty, Hitachi DFT is a good HDD tester. Run the Advanced test to check for bad sectors.

Equium A300D-16C - Battery not detected after replacement

I have a Equium A300D-16C. The original battery was shot so I purchased a Genuine PA3727-1brs 12 cell battery. I have put it in the laptop it appears to charge it but in the corner it still says no battery detected even though its on charge. When I take out the charger it will say unknown remaining.
I have tried the usual tricks of going into device manager and uninstalling the apci compliant control and still it has not sorted it self out. I have also updated my bios to the most recent one. I just wanted to know what else could I do so I can see how much battery is left and if the laptop can recognise i.,

Hello
Is it an original Toshiba battery from an authorized service provider?
Usually the new battery should be detected after first start I would recommend charging the battery while notebook is turned off. Then start notebook with battery only and check if its recognized properly.

Equium A300D-16C - display not working

My girlfriend has an Equium A300D-16C which has been having a few problems lately.
For the past few months, whenever she turns the system on, the display doesn't fire up and it takes several attempts for it to come on.
The strange thing is whenever this happens the system does still boot normally as you can hear the Windows 7 start up sound.
I have been looking into this issue for quite some time now and I'm starting to run out of ideas.
Originally I thought it could've been a cabling issue but upon stripping the laptop down I found the cable was still firmly in place.
I have also tried removing the RAM, HDD and DVD drive but it still doesn't fire up. On the odd occasion it has started up when doing this but upon rebooting it hasn't started again.
I am thinking this could be either a power issue or the motherboard is on its way out. This problem is gradually getting worse (it took over 20 attempts turning it on and off this morning) so eventually it won't come on at all.
To clarify, the system will boot after many attempts but most of the time the display will not turn on (not even the backlight). It does work with an external display on the HDMI so the GPU is working.
I have tried holding the power button with no power source to discharge the system but it doesn't help.
I have also noticed that if you hear it boot and close the lid, upon reopening the lid the display will come on but with the wrong resolution (1024x768) which just puzzles me even more.
Any ideas on what could be wrong? I would rather repair this than just buy a new one as its still a decent system apart from this problem.

It is always problematic to discuss about problems that happen from time to time. Ok in your case most of the time it doesn't work but when it works there is connection between display and mainboard.
On this virtual way we can just speculate what the problem can be. Maybe connection to the mainboard, maybe display controller, display cable, display connector. Who knows?
If there is no even backlight I presume display doesnt get the video signal at all. It must be something on mainboard side.
What you can do? You can contact nearest service and ask for help but if they will say that mainboard must be exchanged it will be pretty expensive. You can try to find similar model on ebay with broken display or some other hardware failure (not mainboard) and exchange the mainboard.
It is really not easy to say what can be done.

Equium A300D-16C - Switches itself off after 3 seconds

I have a Toshiba Equium A300D-16C that will not start up. When you switch it on it begins to start but within 3 seconds switches itself off before it even gets to any type of screen. It then automatically tries to switch on again, then repeats the same cycle of auto off, auto on over and over.
When you put your ear to the bottom of the laptop you can hear the system starting up then you get two very quiet beeps before it switches itself off. Does anyone know what the cause could be or if there is a fix or should i just accept that my laptop of just under two years has died and given up the ghost?
Thanks in advance for any feedback.

> How much would i be looking at to replace cpu/motherboard (not beign a tech wizard in the slightest)
I don't know exactly what is wrong with it as it should be tested before making any conclusion. But the most possible reason is the motherboard - southbridge or power circuit controller. If it's motherboard issue, you will have to pay pretty good money :( as the most expensive part of your laptop. (about 35$-40% from total new laptop price). Don't know even if it's worthy to replace it due to high price. But before, you should contact the Asp (service center):
http://eu.computers.toshiba-europe.com/innovation/generic/ASP_SUPPORT/
Ask them what really happened to it and make decision, then, replace or not.

New battery isn't detected on Equium A300D-16C

Hi,
This is my first post on the site. I have an issue with a new battery on my Equium A300D-16C. (no battery detected)
The original one that I had for the computer died after two years of use so I had to order a new one as a replacement. I have received it and it itself works fine, giving me 90 minutes charge. But the problem is that it isnt detected by the computer when I click on the power icon on the bottom bar of screen, so I dont know how long I have left with it. Also, the orange light that indicates it is charging should go white upon it being full of charge, mine just starts flashing orange after a while (is this when it is fully charged?).
I took the mains out of my computer a few minutes ago and it cut out and I had to switch it back on again, despite the battery being in and it being full of charge (as it has been in all day and the mains have been in for decent length periods).
What can I do to solve this?
Worth mentioning I am not too good with computers so everything might be best explained really, really simply as I am not the cleverest when it comes to this area.
thanks

> Now when i take the mains power out, the computer cuts out and shuts off within minutes without it being able to be turned back on
Seems the battery is empty and therefore notebook shuts down when AC adaptor has been disconnected.
There are two possibilities:
Either the new battery is faulty or there is something wrong with motherboard power supply electronic.
I think both should be checked.

Equium A300D-16C - Windows has failed to start

I have a Toshiba Equium A300D-16C and all of a sudden it starts up and goes onto windows boot manager and says that Windows has failed to start and it wont let me do anything else.
I really dont know what to do and all my uni work is on it.
It says to put the windows installation disk but its not responding to any disks what so ever.
If anyone could help Id be grateful
Thanks

hi Lashay
guessing you have xp on this unit try to reinstall bootfiles.
seems that windows has lost some files...
this could be software or a hardware issue...
"fixboot " and "fixmbr" on recovery console should do this job.
safest way is to get a new hdd and a hdd-usb-adapter!
install operating system on the new hdd,
then connect the old hdd using the usb-adapter to the new system and transfer all user files.
not the system files or maybe you will get the same trouble again!
if there is a serious problem on the hdd its getting worse with every attemp to read the disk...

Strange sound behaviour on Equium A300D-16C

This isn't so much of a problem, just a bit of an annoyance at times really. The sound's working fine on my Equium A300D-16C (sound card and driver all fine on the Device Manager etc. etc., buttons working fine), but, the sound level (volume) keeps changing. I first noticed it as I'd installed the sounds add-on for MS Office 2007, but wasn't always getting sounds, but then other times I was getting very loud sounds, and others very quiet sounds.
I'm +fairly+ sure I'm not accidentally touching any shortcut keys (at least the lit up quick access ones above the keyboard I'm not, but are there any other shortcuts for sound?), but for instance last night at one point I noticed the volume was set at 16, but then half an hour or so later it was 4, and then this morning when I booted it up the volume level was at 0 (but not muted).
As I said, it's not particularly a problem, because if I need to I just adjust the volume to what I want it to, but it's just been puzzling me these last few days as to what might be causing it.

Ah! //Slaps head and goes to hide under a rock// :-D I guess that'd be the one on the front that obviously rests against my slightly rounded middle...? (I am in shape - round's a shape! ;-))
It never even occurred to me that there'd be a dial somewhere! Duh!
Thanks for clearing that up. :)

Equium A300D-16C turns on but the screen shows nothing/stays black

Hi there, I have a Toshiba Equium A300D-16C laptop.
It was fine until now...
When I press the power button, my laptop turns on but the screen remains black / off.
HDD indicator doesn't flash or anything ... ( in case this helps )
I've also tried to remove the battery, hold the power button for 30s and plug the power cord back in... Same thing laptop turns on but screen is black.
I tried to connect my laptop to my PC's monitor using HDMI cable but no success... Laptop turned on but my pc's monitor was showing nothing.
I haven't changed anything inside my laptop or unscrewed it.
PS:
I quite often kept my laptop on the bed/pillow so it may have something to do with overheating or something.
How did I get to this point:
Yesterday my laptop was fine, there was nothing wrong with it... I switched it off at night but when I tried to switch it back on this morning that's where I faced this problem.
Any help would be appreciated.
Many thanks,
Rejanu.

Hello
> I tried to connect my laptop to my PC's monitor using HDMI cable but no success... Laptop turned on but my pc's monitor was showing nothing.
Its very good that you have this test with an external monitor because so you could make sure its not related to internal monitor and its working properly.
Well, you have tried a lot so my personal opinion is its a serious hardware malfunction It could be related to mainboard or CPU in my opinion
I think such hardware diagnostic can only be done from an authorized service provider. I think you should contact the guys. They can help you to get rid of this problem :)

Re: Dvd drive stopped working on my Equium A300D-16C

Hi I need help!
My Equium A300D-16C has stopped recognizing any type of disc, Ive tried double clicking on the drive but they gey kicked out and the message "please insert a disc into the drive" appears.
Having read back previous posts in a bit not to look too much like a dumb blonde and have so far checked the registry values - which are not set, uninstalled the drive via the system device - to no avail. Only had it about 2 months and really cannot be without it.
Any help would be very much appreciated

I tried to install a bluetooth dongle on vista , the bluetooth device was an old one and i dont think it was compatible with vista as it didnt work and it knocked off my webcam,i uninstalled the bluetooth and re-installed the webcam driver from toshiba support, and it worked again.

Mac Mini will not boot after Security Update 2008-007

Hello,
A G4 Mac Mini machine I was asked to take a look at will not boot after the owner (succesfully) installed Security Update 2008-007 from Software Update. Booting always hangs at the blue screen after the Apple logo, and booting in verbose mode reveals that WindowServer is crashing repeatedly. Permissions and filesystems have been repaired, PRAM reset, etc. Safe boot also exhibits the same problem, but it is possible to boot to single user mode. Hardware checks out fine with diagnostic utilities.
Any suggestions on how to fix this? Unfortunately, backups are not available (it's not my machine =).

Hi Arkku , and a warm welcome to the forums!
I'd certainly give Sig's advice a try first.

"OK, restart your computer, hold down Command-s and type in the following:

rm /var/db/.applesetupdone Enter
# The rm command is the remove command which deletes the file.
# Robert: I'd rename the file via: mv /var/db/.applesetupdone /var/db/.applesetupdone.old
reboot Enter
Once you've done that the computer reboots and it's like the first time you used the machine. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!

HP Pavilion 15-n268sa will not boot after windows update (windows 8.1)

After a series of windows update (windows 8.1) my HP Pavilion 15-n268sa will not boot up, no fan noises, no lights no nothing.
I have tried a "hard reset" a number of times with no success.
When the battery is present the white LED flashes 3 times when the power button is pressed.
Please please help.

Hello Cuffy,
Welcome to the HP Forums!
I understand you notebook will not boot after a series of Windows updates.
Can you tell me if you are able to access the HP Recovery Manager by repeatedly tapping the F11 key while the notebook turns on? If you can access this, try doing a system restore to before you installed the updates. If not I would suggest you go through this document: Computer Does Not Start and the LEDs Blink or the Computer Beeps.
If it's the Caps Lock light that is blinking this document will tell you exactly what the error is (spoiler: 3 beeps is a memory failure). This could also explain the failed updates. The updates are stored in the RAM before being applied to the operating system.
You can try reseating the RAM, or using only 1 of the RAM cards, as you have 2x4GB cards. If it still doesn't work with 1 card, try the other card to confirm it has failed.
You can replace defective cards via HP Phone Support if covered under warranty or at the HP Part Store if not covered. You can contact HP Technical Support at 1-800-474-6836 in North America. For all other regions click here.
Hopefully this information helps!

Not Booting after recent Security Patch/Java update

My wife has experienced what many have experienced with the recent update.
MacBook not booting after update (i.e. - "I have no name!")
I have tried everything posted on this topic since 2/13/09, but without any success. Does anyone have the fix for this yet?
Things I have tried:
* I can boot in safe mode (holding "Shift" while restarting)
* I cannot boot from an install disk(s) (holding C while restarting) - I have both a black one from purchase, and two gray ones with purchase from MiniMac
* Booting with verbose - gets stuck at same place as everyone else
Operating in safe mode:
* I can run DU and "repair" drive
* I can see and access the CD/DVD
* I cannot see drive in target drive mode (doesn't ever connect the 2 systems)
* I downloaded the update files from apple and reinstalled them individually (via USB ext Drive) with a reboot in between
* I attempted to update & archive, but I cannot run install CD from any systems disks (see above)
Has anyone figured out how to fix this yet?

Same problem than the other guy who is not mentioning the update in the title.
Powerbook 1.67.
System log said "No user defined computer name" and "using blah blah name" or so.

Obviously since you have iOS 7 you're a developer. As a developer, you signed a NDA with Apple not to discuss the iOS on a public forum. Please log in to the Developer Forum using your credentials and ask for help there, lest you risk having your credentials terminated.
Thanks, and best of luck to you.
