So I've taken my DELL 4100 out of storage and it doesn't power up and the power supply appears to be dead, has anyone successfully converted a standard ATX supply to power a Dell with their propriety power connector? I assume you can splice the ATX wires to the correct connector but i can't seem to …

The problem is that you've not yet formatted your drives after partitioning them. I've had this issue before when there are more than two physical (IDE) drives to be formatted. Try Microsoft support archives for odd issues like this, they generally have the issue covered. "Repeatedly Prompted for …

So back in February I stumbled across a seller that had a job lot of seven socket 7 motherboards, I didn't need one let alone seven but I put in a bid as the auction was ending and no-one else had bid. I ended up getting them all for the whopping price of £7.00! They're all AT form factor but some …

Thanks for the feedback! That makes more sense to me now. I got the board to post but it only recognizes the processor as a 'Pentium family 255Mhz' I guess the board is too old to accept this processor! so far my searches for bios updates have returned nothing. It looks like I'll be swapping CPUs …

I've just been given some old motherboards, mostly pentium 3 and 4 stuff but one was a socket 7 motherboard. based on some searches I think it's a Gateway 4000275, I want to put an AMD k6-2 400AFR into this board but it needs a 6X multiplier. The only option on the board that looks like 6 is the 3/ …

Nope, the failed diode acts like a jumper to ground. You have to have new one or remove it. The diode is in series only after it has failed.

As the TVS diode is directly in series with the 12V rail it will prevent the drive powering up if there has been an overvoltage event. Test your diode with a multimeter, there should be no continuity between the diode legs if the diode is intact. The diode will clamp small surges and recover but …

That's exactly why I started digging around for info! I found this out when I accidentally plugged the wrong adapter into my external drive that contained all my backups. A data recovery company quoted me £150 to take a look and the recovery would have been £1200!! A replacement diode cost me 35 …

If you've over-voltaged your hard drive you can get some life out of it by simply removing the TVS diode (Transitional Voltage Suppressor). Most drives that people think are 'fried' actually just have blown diode. http://i36.tinypic.com/5k1xcn.png If you can solder, it would be best to add a new one …

Good to know, Thanks FGB. I have here in my hand, another barrel battery of the same voltage just waiting to be soldered in - no fuss , no diodes, no difference except the higher current. It's even the same brand. PLEASE! can someone just tell me whether the higher current is acceptable?

I need to replace a barrel type battery, I have another (almost new) barrel type knocking around but it is 8mA, the original is 4mA. Anyone know what would happen if the current supplied to the BIOS was doubled? Will it kill it or will it only draw what it needs? Sorry if this has already been …
