Computer unplugged now wont start

Hello. Thanks in advancement for any kind of aid you deserve to provide me.I have actually an older design HP Pavilion 521N -- I bought it new in 99 or 2000. It has an AMD processor, half a GB of RAM, and so on and so on. It has actually been a really reputable machine for many kind of years. It runs on Windows XP Home.Yesterday I moved it to a new desk. To accomplish this, I shut it down, disconnected all peripherals and also power cord, moved it to the new desk, then reconnected the peripherals and also power cord. (A tiny green light on the back, alongside the power cord plug, started glowing as soon as I plugged it in. But the comptuer will not turn on using the front-panel switch.The hands-on said to unattach, then reconnect every little thing. I did. No go.The hands-on said to inspect one more appliance in the outlet. I did and also it functioned. I replugged the computer in the outlet; it still will certainly not revolve on.Is tright here anypoint I have to try following prior to I haul it dvery own to the computer system repair shop?Thanks for listening.

It may price even more to repair that point than it is worth. Do you check out a fan running on the back of the computer inside the power supply? ( Near the power cord )

your motherboard must have little tiny cables that connect straight to your motherboard, the PWR cable might"ve been disrupted and also may have come loose, shedding use of the power switch in the front panel, make sure you check that to watch if thats ok. following as the previous thcheck out sassist are tright here any kind of fans at all running in the situation reflecting any type of sort of power. I think this is a trouble that you dont need to pay any type of dollar for you simply must play about some more, its a prevalent difficulty as soon as moving approximately a case. check out what u can acquire for an update and also rewrite-up on the forum,thanks

Thanks for your replies and also aid.The power cord is firmly seated in the PSU.I cannot view any PSU switch everywhere.The PSU fan is NOT turning. But a little green light on the ago of the computer that"s component of the PSU is lighted. I have the right to likewise hear a really faint hum from the PSU. (No various other fans are turning, either).I have actually disconnected and relinked the plug from the switch to the motherboard.I have disassociated and also relinked a number of other plugs to the drives; however the plug on the motherboard that brings the power from the PSU is really tough to gain to. It is seated firmly in location.

Definetly soudns prefer a PSU problem then.I would definetly want to make it 100 % certain though before you go out and gain it looked favor and also then u pay 89.00 dollars to acquire it looked at and also uncover out something u must currently know.GET RID of allll peripherals first simply leave PSU installed, if you have actually another computer system in your house switch out the power supplys and test that one via ur brand-new computer system.U dont need the front panel to turn on ur computer system tright here should be a button on ur MOBO that turns it on.That power connector that you "cant" acquire to because it is firmly in location is key to figuring out if this realy is a PSU difficulty. Find a means to that power connector and also rerelocate it and reset it earlier into location firmly. If there"s a method to affix it to the motherboard there"s always a way to disconnect it from the MOBO.but from whats going on i would certainly definetly assume a PSU problem.

If you have actually a DC voltmeter take among the totally free molex connectors and read the voltage tbelow, if tright here is no power it might be the PSU. To discover out if it is a motherboard problem you have the right to remove the PSU 20/4 pin connector from the motherboard through the PSU unplugged from the wall, you will certainly must place a jumper in between the socket of the green wire and any kind of black wire, this replaces the motherboard founding attribute, plug the PSU ago in and take a volt meter and read the different rail voltages.This page will certainly show the shade codes and associated voltages, the twenty pin attach is on the first web page, the twenty 4 pin connector have the right to be seen by using the link at the bottom of the page.

Family and also loved ones will always be a priority in my daily life.  You never before recognize when one will certainly leave you.

The HP power gives have an LED inside of them that tells you whether the power supply is great or not. There is a chance it is not working appropriately yet if the LED is functioning, it is then commonly the motherboard or negative RAM.If you deserve to open then situation, deserve to you view if tbelow is an LED lit on the motherboard? Tright here is usually a small green one, for standby power.DR

That power supply is toast. You have to gain a brand-new computer system and usage the drive from the damaged one as a file drive. Get all your information from it. Make a hamster cage out of the old HP box.
