This is a discussion on Toshiba A300 Laptop BIOS help within the Motherboards, Bios & CPU forums, part of the Tech Support Forum category. Hello,
My Toshiba Laptop is a A300 with model number PSAGCA-03C010 however this model is not listed on the Toshiba
My Toshiba Laptop is a A300 with model number PSAGCA-03C010 however this model is not listed on the Toshiba website with their BIOS downloads.
I've run msinfo32 on a working laptop of the same model, and it says the bios model is Insyde 2.20 (and when you boot it, it has the H2 logo).
I've also read somewhere people can only flash certain models of the A300 with a USB disk or USB floppy drive. Going to try a USB first.
However, my problem is I have 2 of these models and both of them do not load the BIOS screen at all, they just power on for a few seconds and display nothing.
If someone could point me in the right direction of downloading the correct BIOS, and perhaps flashing it (to determine if this is a BIOS problem or a motherboard problem), that would be great, as I have not had any kind of issues with BIOS problems before. Googling Insyde 2.20 bios download does not help. Please note they both power on for about the same time.
I have also downloaded a similar BIOS from toshiba, however the files were not of the kind you guys talk about when flashing with a USB drive. There was a bunch of setup files, batch files and DLL files. Tried to boot from this but didn't work.
If there's anything I can do to help let me know, I've already had someone suggest to download and run software called BIOS Backup ToolKit on the working laptop to get the BIOS file, however Total Antivirus shows multiple infections and I'm not sure if it would even work.
I downloaded it, and am trying to get it to b flashed somehow without windows. I've extracted the files, and the .iso inside the files, to find the .fd files that people normally talk about flashing with. Loaded them to USB and Floppy, and tried a number of hot key combo's that people normally talk about for this model to be flashed. I managed to get it to stay powered on using combinations of Fn + B + F + Esc + maybe even a 0. However it tried to read the floppy, then fails, and the USB doesn't do anything. Toshiba tech support won't tell me how, and wouldn't even provide a bios/driver download for me as they said the laptop was outdated haha.
I think the motherboards may be damaged. I burned the iso to a DVD (it has a DVD drive) then started it with the hot keys and it started up, displayed nothing as usual, and then tried to read the dvd for about 30 seconds. Then stopped. So I thought, maybe it needs to reboot, however now it won't reboot with the hot keys haha. The laptops may have moisture damage on the mainboards too.
I've never heard of putting the BIOS on a CD/DVD as an ISO....not to say that you can't but I've never seen it done.
The usual method to update the BIOS is to download file either by saving it to the desktop and drag/drop to a USB drive or download directly to the USB.
Next, while USB is still inserted in the PC reboot and enter into the BIOS....then navigate the BIOS to update the BIOS and follow the prompts to extract the new BIOS update and install it. Then reboot. This is the old way which can be over whelming for the novice but youtube has some great videos on the subject for just about every mobo, laptop and PC out there.
Like Wizmo stated, the new way is with in windows per manufacturer procedure....which I've used a lot and never had an issue with it.
Here's a video for an Asus mobo so you have an idea of what to do.
I've tested the bootable floppy and CD on the non working laptops I have of this model, and they attempt to read the floppy drive a fraction of a second and spins the cd a couple of times but nothing happens. I have a working model of this laptop, and it seems to be able to read the floppy and CD fine. Do you think this could be a motherboard problem?
also the CMOS battery has failed on the board of the working one, and because the battery is soldered to the board, I'd prefer to just use an app to update the system time every day. I found a really good freeware one a while ago, but now I've lost it (there seems to be a few) but the one I had a while ago was really helpful. Just looked like a little dialog box that selected its time zone server and updated.
@plankton23, some motherboards used to come with the option of booting from the CD/DVD, so essentially the motherboard CD/DVD would have the BIOS firmware in it, and when started with specific keystrokes would launch the BIOS recovery and flash the known good stable ROM that was a part of the Motherboard Disc.
This would help when BIOS crashes or a firmware issue causes it to fail.
Now if you need a "floppy disk", use Rufus to flash the ISO as a FDD Image to your USB stick (one of the options), and then start the laptop and use your key combinations.
Are you sure both laptops need BIOS updates and that is in fact the issue ? Are there any diagnostic lights or do you see any patterns in sound/lights ?
There are no warning sounds or lights. sometimes it will power on for half a second, but when you get it to work with the keys, it will work forever as long as its plugged in. The boot works on the working laptop though, and I am following the instructions from the toshiba software the guy provided above on how to flash it (first from floppy, then redirect to cd drive.) It reads it for half a second then stops, but with the working one it reads it and then proceeds with its processes.
Also the CD spins a bit but doesnt look like it loads anything as the screen is still blank. No hard drive noises.
Any chance you can remove the RAM modules and reset all of them ? This time, use a white eraser, clean the contacts on the module and then reseat them, ensure they lock in place. Remove eraser debris from them before inserting, also use anti-static gloves and on a cardboard laid out to avoid static.
Possible Virus on Windows 7 Hello,
I am pretty sure I have a virus, but my antivirus programs have been unsuccessful in finding it. I ran a lot of different things at one point (Norton Antivirus, ESOD, rkill, etc.). I am really not computer savy at all, so I can not give any more information on that front. The problem I...
