Hi, apologies if this exact query has been answered before, but just wanted to check. I have an E521 which doesn't start up running on Vista. An amber light at the front of the pc remains solid (no blinking) and there are no diagnostic lights that come up. The fan seems to be working and the hard drive vibrates a little. Does that mean i need to change the power supply or should i try some alternative diagnostics first before buying a power supply? Thanks
The following is Dell's solution for a solid amber power light:
Remove and then reinstall the memory modules.
Remove and then reinstall any cards.
Remove and then reinstall the graphics card, if applicable.
Ensure that all power cables are securely connected to the system board
The e521 Diagnostic Codes and Troubleshooter is HERE.
If the above does not make a difference and if you are comfortable working around computers, you could try the following:Note: The only 100% method of testing a PSU, is to install a know working power supply.Unplug the cord from the power supply, hold the power button in for about 15/20 seconds, open the case, unplug the 24-pin power connector from the motherboard and jump the Green wire to one of the Black wires, reconnect the power cord and power the system, if power supply's fan and the hard drive run, then the PSU should be good.Note: Do not remove any wires from the plug, use a small piece of wire or a paper clip as a jumper.
Power supply checks out and the system still does not work, again remove the power cord, hold the power button in for several seconds to discharge the residue power, reconnect the 24-pin connector to the motherboard.Remove all the PCI cards, the video card [if applicable], memory, all peripherals, disconnect the data and power cables to all the drives, check that the front panel cable is connected to motherboard, with nothing else connected to the system, reconnect the power cable and power the system on. If you do not get any beep codes and/or there is no change in the diagnostic lights, it would appear that the motherboard and/ or the processor has died.Bev.

Thanks, when Dell say remove and reinstall cards/memory modules am i right in thinking they're saying take the module out and put it back into its slot again? There is no additional software or harder to 'install" right? I shall try these recommendations out over the wkend, thank you.
Yes, that is what Dell means.
Thanks. No difference when i remove and re-install the cards. However, when i jump the power supply green and black cables and then switch the power on, the fan does not work. When i do not jump the cables and just try to switch the pc on without changing any settings, the fan does work.
I am guessing its the power supply? I believ the existing psu is 305W ATX 24 pin. I've found what looks like a compatible replacement but its 450W (http://www.amazon.co.uk/450W-Gold-Silent-Power-Supply/dp/B000O38OPG/ref=sr_1_fkmr3_1?ie=UTF8&qid=1283099729&sr=8-1-fkmr3). Will that be a problem? thanks again.
Sorry, cannot say if the CIT 450W Gold 12Cm Silent Atx Power Supply is compatible with the e521, as Amazon does not list details of the power connectors, but the wattage is fine.
The e521 does not use Dell proprietary power supplies, you can install most standard ATX power supplies with either a 24-pin or 20+4-pin main motherboard power connector. As the E521 has an open back panel, a power supply with or without the on/off switch can be installed. You should be able to buy a compatible power supply from either a local or online computer store.Note: You will need a power supply, with four SATA power connectors.Bev.
Thanks. How about http://www.amazon.co.uk/Enhance-Supply-format-Active-selecting/dp/B000BI7ZQS/ref=tag_tdp_sv_edpp_i
350W ATX POWER SUPPLY FOR PC 1 x 20 pin ATX Connector 4 x 4-pin P4 Connector 4 x Molex IDE Connector 1 x Floppy Connector Dimensions 150mm x 140mm x 85mm
I guess i cant take the Sata cables from the existing psu and re-use them? Presume the psu has to have 4 sata cables coming out of it. thanks
The 350w power supply, is NOT compatible, it has only a 20-pin main motherboard power connector [ the e521 requires either a 24-pin, or 20+4-pin connector]
You are right, the SATA cables cannot be transfered.
Usually a power supply will two SATA power connectors on each cable.
A power supply with four SATA power connectors, similar to the 550w PSU, HERE is needed.
Perfect, thanks for all your help.
Happy to have helped.
