Question about Computers & Internet
My computer is HP Media Center m7250. Today, we experienced power outage. After that, I can not power up the computer. There is a green light on the power module, which is flashing. Then I pulled the power plug off. the green light still flashing, but the flashing slows down and finally dim. When I plug power back, the green light flashing again at a constant pace. Does anyone experience the same problem and know a solution.
BTW, HP costomer support said they can boot my computer remotely if I pay $99 for extended warranty.
Thank you sooo much. I have an HP m1206n or something like that with the same exact problem. Followed all the instructions at http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&dlc=en&product=471588&rule=38432&docname=bph06788#bph06788_section_2
the solution here says to get the computer serviced or replace the mother board. I figured I would try your trick first. Worked like a charm. Just as long as you don't pull power from the tower then the green led light on the back begins flashing again.
I have just come back from holiday and had switched off all plugs. When I went to switch everything back on the green light by the power socket on my HP MC m7000 flashes constantly but does not power up.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

The 'cure' for this is to replace the power supply.
Inside your power supply are Electrolytic Capacitors. These are Filters for a power supply. To simplify detailing the construction of them, let's just say they are small aluminum 'cans', with an Electrolytic paste inside.
They are used to filter the incoming AC electricity from your house, (Business, school, whatever) They are also used to filter the DC electricity, coming out of the power supply. (Your computer power supply converts AC electricity, into DC electricity)
The one's we're going to concern ourselves with here, are the Output capacitors. The one's that filter raw DC into true DC.
When a capacitor (Of this type) starts failing, it's because Electrolytic paste is developing a gas inside. (Hydrogen gas) The gas expands, breaks a seal, and begins pushing the paste out. (Oozing out)
So much paste loss, and the capacitor can still function, but at a weakened state.
These capacitors deal with the voltage power rail for a power supply. Weak capacitor? Weak voltage rail!
Your processor requires a steady, 'clean', supply of DC voltage. It operates in a very TIGHT tolerance. Too much, or too little, it turns off. Too little it doesn't turn on.
The power surge has weakened Electrolytic Capacitors inside your power supply.
Lights light up. Fans spin. It sounds like the harddrive is running. (It IS! It's just sitting there spinning. More about that to come)
ALL the lights use less than 1 watt. EACH fan uses 2 to 3 Watts. The harddrive just sitting there spinning, uses about 5 Watts.
When it's time for the processor to turn on, (BIOS turns it on), it can't! Processors use 55 Watts to 125 Watts. Depends on the processor make and model.
Your harddrive just is just sitting there spinning, because the processor isn't running.
Solution? Replace the power supply, be happy.

check if you bios built in video is enable and try to disable that and use your video card, if you are running in built in video card then increase the size of the video memory

chipset drivers would be your best bet of the group. Memory card readers are usually plugged into USB headers on the motherboard.

Hi, I went to the HP page for HP Compaq Presario SR1620NX -
and searched for SM bus controller.
There was a help page that came up and looked like it may work.
It looks like the next step is to determine which chipset you have and go there (intel, AMD, nvidia) HP offers a link to these websites at the bottom of the article.
Have fun, Good luck.
