3 Short 1 Long Beep
My Lenovo Thinkpad X1 Carbon laptop has problems with its BIOS and motherboard information. It boots unreliably, getting stuck on a black screen when it fails. The times it boots successfully, it throws random errors from a pool, such as:
0187: EAIA data access error.0251: System CMOS Checksum bad - Default configuration used.2200: Machine Type and Serial Number are invalid.2201: Machine UUID is invalid.

I did all of thease works but not working. I heared 3 Long 2 short beeps pause 3 long 2 short beeps. Repaeat for 3 or 4 times. My laptop is Lenovo G505. Please help me. I've recently purchased 5 Lenovo M700 desktop PC's, so I tried upgrading the RAM's on one of the PC's I removed one or the RAMs from the other PC and slotted it into the other one so when I booted up there was 3 beeps and one long beep sound and there is also no display on the screen.
1 Long 3 Short Beeps Asus Motherboard
I'm updating my BIOS as per this tutorial, booting through a USB Stick. The laptop is connected to the AC.
The utility asked me the administrator password, and after some instructions and waiting, it rebooted, and has spent over an hour on a black screen, with the power light slowly phasing in and out.
Even though a BIOS update is a very delicate matter, I figure it can't take that long, but when I touch the power off button, it sounds two short beeps, followed by three more short beeps, and the power remains on. This sequence is not covered in the documentation.
What does it mean? Download swiftshader 3.0 dll. Is it reasonably safe to hold the button and turn off the laptop?
