As long as you have one good computer up, use the serial numbers/model numbers and I recommend goggle as a search engine, simply type those in till you find the make of each, usually most will supply you with a link that you can download the manual's and tech information and what ever other requirements you might need!

If I can further help you let me know, I will be happy to look up the information for you when I can and supply some links that may help. Remember tho I would need the information about your computer and or laptop serial numbers/ model numbers/ make/ motherboard identification / etc


Thanks,,,,,Larry

How to bypass toshiba laptop password on harddrive?


Actually its really difficult as well as risky process to reset he hard drive password on a laptop as you can not bypass it but you can definatly reset it. But that requires you to take out the CMOS battery and reinsert it which is on the motherboard, so it ultimately requires dissembling the laptop.

I will not suggest you to do that as it is a risky process. Contact the customer care and the will help you out. Or you will have to mannually take your laptop to service center if its hard ware locked.

Thanks !!

Bios Beep code


Beep Code Manual, Better Than Gold Techies, American Megatrends Int. & Phoenix
(I'm IT, I use these codes to trouble shoot hardware issues at my job. Enjoy) cold.gif
BIOS Beep Codes
When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected. Because there are many brands of BIOS, there are no standard beep codes for every BIOS.
The two most-used brands are AMI (American Megatrends International) and Phoenix.
Below are listed the beep codes for AMI systems, and here are the beep codes for Phoenix systems.

AMI Beep Codes
Beep Code Meaning 1 beep DRAM refresh failure. There is a problem in the system memory or the motherboard. 2 beeps Memory parity error. The parity circuit is not working properly. 3 beeps Base 64K RAM failure. There is a problem with the first 64K of system memory. 4 beeps System timer not operational. There is problem with the timer(s) that control functions on the motherboard. 5 beeps Processor failure. The system CPU has failed. 6 beeps Gate A20/keyboard controller failure. The keyboard IC controller has failed, preventing gate A20 from switching the processor to protect mode. 7 beeps Virtual mode exception error. 8 beeps Video memory error. The BIOS cannot write to the frame buffer memory on the video card. 9 beeps ROM checksum error. The BIOS ROM chip on the motherboard is likely faulty. 10 beeps CMOS checksum error. Something on the motherboard is causing an error when trying to interact with the CMOS. 11 beeps Bad cache memory. An error in the level 2 cache memory. 1 long beep, 2 short Failure in the video system. 1 long beep, 3 short A failure has been detected in memory above 64K. 1 long beep, 8 short Display test failure. Continuous beeping A problem with the memory or video. BIOS Beep Codes

Phoenix Beep Codes
Phoenix uses sequences of beeps to indicate problems. The "-" between each number below indicates a pause between each beep sequence. For example, 1-2-3 indicates one beep, followed by a pause and two beeps, followed by a pause and three beeps. Phoenix version before 4.x use 3-beep codes, while Phoenix versions starting with 4.x use 4-beep codes. Click here for AMI BIOS beep codes. 4-Beep Codes Beep Code Meaning 1-1-1-3 Faulty CPU/motherboard. Verify real mode. 1-1-2-1 Faulty CPU/motherboard. 1-1-2-3 Faulty motherboard or one of its components. 1-1-3-1 Faulty motherboard or one of its components. Initialize chipset registers with initial POST values. 1-1-3-2 Faulty motherboard or one of its components. 1-1-3-3 Faulty motherboard or one of its components.
