Sorry to hear that... Well the first option I would try is to:

Uninstall the Web cam Driver

Go to Acer's Support Site

Download the web cam driver and see if that fixes the problem!

Hello, My name is Keith and I run a small computer repair store in Alabama. I have a customer that has a Toshiba Satellite C75D-B7200 and he cannot remember the BIOS password


Hello Keith!


First of all, there is an OEM Toshiba software out there to flash the bios directly from windows, doing so will remove any password and restore the BIOS to it's original settings with an updated version. If that still doesn't work, consider a 3rd party software to recover the password or if the bios is socketed and none of the above solutions worked, order a new one directly from Toshiba.

Be ABSOLUTELY SURE to flash the BIOS with the correct version according to the model number of the laptop and that you connect the laptop with the power adaptor so it does not run out of battery in the middle of the process failing to do so might rend the computer unusable with a corrupted BIOS file.

1) First thing to check is the AC adapter (Charger) power output.
It is 19 Volts (DC)
Suggest use a multimeter to check.
An economical, yet good enough for this test, multimeter, can be purchased for as little as $8 to $12.
Available in a multitude of stores. An auto parts store is but one example.

http://www.youtube.com/watch?v=LnTxs0o5CJA

In the above video ->
DO NOT TEST THE POWER LINE CORD -> GOING INTO THE AC ADAPTER (Charger) 0:00 to 3:58 in video.

-> TOO DANGEROUS. Take the power cord to a pro to test it.
AGAIN -> DO NOT TEST THE POWER CORD
110 to 220 volts will give you a BAD SHOCK to -> FATAL <-
(Can kill you)

For the second part of the test starting at 3:58, it is okay.
You will be testing for 19 Volts -> DC
If the voltage shown is not at least 17.1 Volts (DC), (90 percent),
the AC adapter is no good.
Replace.

AC adapter checks out?
Then it's time to check the DC Power Jack.
(DC_IN on the laptop. The jack on the laptop you plug the AC adapter into )

2) Remove the Battery. With a non-metallic object, gently see if you can wiggle the center pin of the DC Power Jack around.
ANY perceptible movement means a bad DC Power jack.

Good news is that it is Not soldered to the motherboard. It is attached to wires, that are attached to a small white plug in connector. (DC Power Jack is connected to a harness),

http://www.amazon.com/TOSHIBA-NB100-NETBOOK-CABLE-HARNESS/dp/B005J9CEXS

(You can click on the photo to enlarge)

Once removed, you can check it for continuity with the multimeter, set to OHM. (1K)
Or have it checked.

The DC Power Jack harness, plugs into the CN5 connector on the motherboard,

http://www.aliexpress.com/store/product/MOTHERBOARD-FOR-TOSHIBA-NB100-NB105-V000155020-6050A2213401-100-TSTED-GOOD/202172_485947825.html

Looking at the motherboard in the photo, you will see two green squares. The middle square is the Processor.

The green square to the right is what I want you to look at. Specifically, the small white connector to the right of it.
(The green square is a chipset. It has a white triangle < pointing to the Top/Right corner)

Put your mouse cursor on the photo. (Magnified view)
Go to the small white connector to the right, of the green square
I indicated above.
Has a small white arrow ( > ) pointing to the Top/Left corner of the white connector.
This is the CN5 connector on the motherboard.

If the DC Power Jack harness is not the problem, then the problem is Power MOSFET's on the motherboard, and or Capacitors.
(Ceramic SMD capacitor/s)

[Just basic info. Pertains to an HP laptop. Just want you to see about Power MOSFET's,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html ]

Choice is yours, whether you wish to have bad electronic components replaced, or replace the motherboard.
May be more feasible for you to replace the motherboard.

Set the bios password and forgotten whaat it is


You need to preform a Acer Aspire One BIOS Recovery

instructions here: http://macles.blogspot.com/2008/08/acer-aspire-one-bios-recovery.html

Summary:
You need a flash drive formatted as fat (Right click on drive. Click format. Select fat for file system. Press start)
Down load the bios 3310 from here: http://macles.blogspot.com/p/acer-aspire-one-bios.html
Extract all files. Put both FLASHIT.EXE and the BIOS file with FD suffix in the root directory of the flash drive. The files must not be in a folder. Rename the BIOS file to ZG5IA32.FD before proceeding. It only works with this exact filename.

Make sure laptop is off and has battery and power plugged in.

Plug in flash drive to netbook. Press Fn and Esc simultaneously, keep them pressed and press the power button. Release Fn+Esc after a few seconds. The power button starts blinking at this point. Press it once. The netbook will now access the files on the flash drive and initiate flashing the BIOS. After a while the power button stops blinking, and the netbook reboots by itself. Wait patiently.

If it doesn't reboot, but keeps blinking, wait at least a few minutes before turning it off, and try again.

My Acer netbook doesn't turn on. The battery is full but when I press the power button it becomes green but the screen remains black. What should I do???


Try to reflash the BIOS of this particular model. Follow the guide below to try and repair the netbook.

Try this fix….all you need is a flash drive, the BIOS files from Acer support Downloads and 10 minutes of your time.

Acer One Black Screen of Death Repair…..

In most cases the black screen of death for the Acer One is due to a bad update or corrupt BIOS. In 90% of the cases, this black screen can be cured by flashing the BIOS of the Acer One.
The first thing you will need besides the netbook is a flash drive, preferably a 1 GB version so you have plenty of room. Make sure it a flash drive and not a reader or mp3 player.
Go to the Acer support site and go to service and support and go to the drivers download section. Navigate to the exact model of your Acer One, it will be labeled on the bottom of the case. It will be something like AOA150 etc….
Once you choose the model, choose BIOS and download the latest that is listed. Save it to a folder on the desktop so you can find it later. Now find the file and unzip it to that folder. When the files are unzipped they will all be listed.
Now go to “My Computer” in the control panel and find the flash drive listed. Right click on the flash drive and scroll down to “Format”. Choose “FAT” as the format….not fat32 and not ntfs. Run the format, hit apply and accept and the flash drive will be formatted to the “FAT” file system, this will allow it to boot your computer and flash the new BIOS.
Now go to the folder that has the unzipped BIOS files. Now find the folder named…. “Dos_Flash…open this folder and you will find the file that has the version number of the BIOS files needed to flash the BIOS. Right click on this file and scroll down to “Rename”, choose rename. You have to change this file name to the following…..zg5ia32.fd
Now, copy this renamed file to the flash drive that you previously formatted and also copy the file, Flashit.exe to the drive as well. This file is in the same folder as the one you previously renamed.
Now make sure the netbook is off and is fully charged. Now connect the flash drive to any of the available USB slots. Now, press the “Fn” key and hold it as well as the “Escape” key and hold it. Hold these two down together and do not let go of them. While you are holding these two keys down, press the power button and hold it down until you see the green power indicator light comes on and starts blinking…once this happens, let go of the other buttons and observe the indicator light on the flash drive. It should also start blinking indicating files being read on the flash drive. Now, just wait up to 1-10 minutes for the BIOS to be written and flashed. If it all goes well…..the system should boot up without incident and without any data loss.

I try update my bio on my ao0751h netbook acer, and doesn't successfully, now my netbook doesn't turn on. How i recovery a bios?


Solution 1: Boot-block BIOS
Modern motherboards have a boot-block BIOS. This is small area of the BIOS that doesn't get overwritten when you flash a BIOS. The boot-block BIOS only has support for the floppy drive.If you have a PCI video card,you won't see anything on the screen because the boot-block BIOs only supports an ISA videocard.
Award: The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable diskette. Copy an Award flasher & the correct BIOS *.bin file on the floppy and execute it automaticly by putting awdflash *.bin in the AUTOEXEC.BAT file.
AMI: The AMI boot-block BIOS will look for a AMIBOOT.ROM file on a diskette. Copy and rename the correct BIOS file on the floppy and power up the PC. The floppy doesn't need to be bootable. You will see the PC read the floppy, after about 4 minutes you will hear 4 beeps, this means the transfer is done. Reboot the PC and modify the CMOS for your configuration.
Solution 2: Get a new BIOS chip
  1. Contact your motherboard manufacturer to see if they sell BIOS chips. Some motherboard manufactures send them for free.
  2. Contact a company that sells pre-flashed chips, like Unicore Software, FlashBIOS.ORG, BadFlash or Bios World
Solution 3: Hot-swapping
Note: I'm not responsible for any damage this method may do to you or your computer !
  1. Replace the corrupt chip by a working one. The best option is to take the working BIOS chip from a motherboard which has the same chipset although that's not absolutely necessary. It just has to give you a chance of booting into DOS. Before pulling the working BIOS chip out of it's original motherboard, set the System BIOS cacheable option in the BIOS to enabled.
  2. After you have put the working BIOS in the motherboard with the corrupt BIOS boot the system to DOS (with a floppy or HD).
  3. Now replace (while the computer is powered on) the working BIOS chip with the corrupt one.
  4. Flash an appropriate BIOS to the corrupt BIOS and reboot.

Solution 4: (for Intel motherboards)
  1. Change Flash Recovery jumper to the recovery mode position (not all products have this feature)
  2. Install the bootable upgrade diskette into drive A:
  3. Reboot the system
  4. Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As soon as the drive LED goes off, the recovery is complete.
  5. Turn the system off
  6. Change the Flash Recovery jumper back to the default position
  7. Leave the upgrade floppy in drive A: and turn the system on
  8. Continue with the original upgrade

Toshiba Satellite 3000 hard drive


If you saved the old bios info on a floppy before you flashed your bios with the new bios info, you can reflash and restore your bios back to the original. However if you didn't save the info which is usually saved as a .bin file you still have a chance to re flash back to original settings. Use a friends computer with a floppy drive and download your original bios program from the toshiba web site or any other site which has bios flash programs/utility file to the floppy and reflash. If you laptop doesn't have a built in floppy you can use aexternal one that connects to the rs232 parallel printer connector. Thats if your laptop has one of these now becoming an obsolete port on most if not all laptops. As this port is being replaced by the USB port.
