Toshiba satellite A80 continuous beep on boot

Thread Starter 
I am working on this A80.

On booting to the Toshiba screen, the system emits a high pitched continuous beep and the key board freezes. I did the following:
1. I replaced the RAM but the problem continued.
2. I replaced the HDD but the problem still continued.
3. I tried to but from the recovery disk. It booted alright but I couldn't use the keyboard to issue instructions. I could only boot the DVD after I held down the PRT SCRN +F12 buttons for about 3 mins. Since just holding the f12 or C keys alone does not stop the beep. All the same no dice.
4. Lastly I disassemble the whole system and disconnected the RTC (CMOS) battery. on coupling back the beep is still there.

WHAT ELSE DO I DO?
I'm almost frustrated now. can anybody help out there?

It sounds like it could either be a faulty memory module or possibly a faulty video chip. Download "memtest86" and check out the memory modules one at a time. Also, try booting into "safe mode" and see if that works. If it does, go to Control Panel>Hardware manager and see if there are any conflicts (possible video)

Can you use the kb to get into the bios? If so go into the bios and enable legacy devices. Then get a usb (or PS2 if you have a port) KB and disconnect the laptops internal kb.

Hi, can I hijack this really old thread? I'm new and I know starting a new thread is usually frowned upon if there are others still open with the same issue.

 

I have a 3 year old L505 series running windows 7 and I have pretty much the same problem.

The laptop boots to the toshiba screen and wants me to either select the operating system (windows 7) or diag options. At that point there is no response from either the built in kb or an external usb kb. I did notice the screen kind of flickering a little, see more on that below.

I have tried the following:

F2: If I go into the bios, I can navigate freely and all the buttons on both kb’s work fine. Tried to set everything back to default but still having the same issue.

F8: Beeps continuously, safe mode doesn’t even begin to load.

F12: Tried to load windows disk and run utility. Some times it beeped continuously no-stop but randomly it would eventually load. Once in the start up options if I select any of the drop down menus, the selection would zip up to the top option. Like as if I was holding down the up arrow. That would explain the screen flickering, more on that later. I tried to do a system restore but I got an error and was not able to initiate the restore on several tries. System scan resulted in no errors.

I then plugged the hard drive into my desktop to pull the files out before I try re-install. For some reason my desktop booted off the laptop hard drive, but it worked just fine. I then popped it into my hot swap dock and scanned the whole drive with the pro version of malware bytes and portable scanner. Just found a few cookies.

After that, I figured that it must be hardware related. So I cracked open the laptop and unplugged the keyboard from the mb. Rebooted with the USB kb and still had the same problem with the seemingly stuck up-arrow.

Tried installing brand new memory, didn’t work.

Tired re-installing the OS, got through the initial install, but upon reboot the system just beeps and doesn’t make it to the toshiba screen.

I am out of ideas and about to scrap this perfectly good laptop, please help.

Jay.
