| 157412 | 2003-07-04 06:08:00 | Just wondered if anyone knew a work around for the PS2 keyboard port not working. Reset bios, but still no response although keyboard LED's do flash on startup and there is +5V getting to K/brd. Do you know you can't get into that damn BIOS without that &#%$@* keyboard. MOBO is an EPOX (haven't got number as forgot to note) and running a 600MHz Celeron. |

| 157413 | 2003-07-04 12:10:00 | checked the pins on the ps2 side of the keyboard, they maybe squeezed together or get a ps2 to usb adaptor | beama (111) | ||
| 157414 | 2003-07-04 12:33:00 | You could try a USB keybd, but if USB Keybd isn't enabled in the BIOS it won't work. (and it isn't enabled by default on most m/bds) Also Halt on no errors would have to be enabled in the BIOS. Most likely cause is a failure of the motherboards keybd controller rather than a PS2 port failure. The other likely cause is a BIOS Failure. If this is the case, it's ready for the knackers yard. The BIOS chip could have "crept" The can start to work their way out over time if it is a socket type. Press down hard on the BIOS Chip & see if it pops back in. (make sure power to the board is off) Heating the BIOS chip up with a hairdryer can also get it started sometimes. I did ressurect one board about a year ago by removing the board, putting the edge of it on a block of wood & tapping the PS2 connection with a hammer, I then gave the back of the board a spray with CRC. As older boards expand & contract with heat, solder joints can fracture & a wee spray with CRC can help make contact again. I give it a wee spray every couple of weeks & it's still going. Bit mickey mouse (& probably bordering on downright dangerous, but what the hell it worked) Please post back if you come up with a solution, as I have a couple more here with the same problem. |

| 157415 | 2003-07-05 03:05:00 | I have a strong idea that (because it's necessary) USB is enabled in the BIOS during the POST. If you have a PS/2 or Din5 keyboard, and don't explicitly enable USB keyboard in the setup, it is then disabled for normal running. But if the only keyboard is a USB one ... They have thought of it. :D |

| 157416 | 2003-07-05 04:18:00 | Thanks for the replies there. Sorry beama, forgot to mention I had tried another known good keyboard. Stumped badly, will have a look at BIOS chip. Think I may leave the CRC idea though. I checked for Dry joints and the chip protector on board, but they are OK. Graham L . I will borrow a USB keyboard and try. The original is PS2, and as I have reset the BIOS, who knows. :) Worth a crack, it's just so frustrating seeing the instruction "Press F1 to continue" when it totally ignores keyboard. :D |

| 157417 | 2003-07-05 04:22:00 | If you've got USB sockets I'm pretty sure it will work. I think they call the setting which works with keyboards and mice "Legacy USB" (or something similar). CRC and other such things are probably best kept out of circuitry. They can seep up into components like electrolytic capacitors, and have unpredictable reactions. |

| 157418 | 2003-07-05 05:13:00 | Just reset the BIOS on 5 machines & none of them had USB keyboard enabled by default (all boards were a couple of years old though) so it will be interesting to see if it does work. I might just get a USB keyboard myself & try it out. Yeah I wouldn't recommend soaking the board, just a quick light spray, especially at the back of the PS2 connection. If you put on enough for it to "seep up into components like electrolytic capacitors" then you will definitely be asking for trouble. |
