Hp Proliant ML350 g4 will not power on. System was on but not responding so used power button to shut down. Now no response to pressing power button. No LEDs lit anywhere. Fans running on power supplies.


sounds like the motherboard has gone.... you could try changing the PSU and popping out some of the ram boards to see if that helps. but with the symptoms you've said, i'd say its the motherboard.

Installing new cpu on a emachine


According to the specs I have Serena, the eMachines eTower 633i Desktop PC, uses a TriGem Cognac motherboard.

[TriGem is the manufacturer, Cognac is the model.
Note it is Not the TriGem Cognac+ ]

http://www.motherboards.org/mobot/motherboards_d/Trigem/Cognac/

Specifications. (You can click on the photo to enlarge)

PDF motherboard manual,

http://www.elhvb.com/mboards/TriGem/manuals/index.html

Click on - Cognac - in the left side of the list.

Going back to the Motherboards.org page;
(Nothing like upside down photo information, and the motherboard is turned 90 degrees to the Right, to how it actually sits in your computer case )

The processor socket is a Socket 370,

http://en.wikipedia.org/wiki/Socket_370

Used for Intel Pentium III processors, and intel 'Celey' processors.

(Excuse me......Celeron.
An Intel Pentium III processor has TWICE the L2 cache, that a comparable Intel Celeron has.
The cache for a Processor is a small memory area for the Processor.

It is the First memory the Processor accesses.
The Ram Memory is second, and the Harddrive is third.
More cache for a Processor makes it more faster )

The motherboard chipset is an Intel 810.

The Northbridge chip of the motherboard chipset, is an Intel 82810.
The Southbridge chip is an Intel 82801AA, or an Intel 82801AB.
(Intel ICH, or Intel ICH0 )

Looking at the chart, and reading across, you can see what the Intel 810 motherboard chipset supports;

1) Processors: Intel Celeron, or Intel Pentium II, or Intel Pentium III.

2) Processor Front Side Bus: (FSB) 66MegaHertz, or 100MHz.

3) SDR Sdram ram memory at 100Megahertz.

[Single Data Rate Sdram is often just referred to as Sdram.

Erroneous.
Double Data Rate Sdram is also Sdram (DDR Sdram)
Synchronous Dynamic Random Access Memory
So is DDR2 Sdram, and DDR3 Sdram ]

Also referred to as PC100.

So when looking for a CPU you look for;

1) Fits in a Socket 370 processor socket.
Yep. The best is going to be an Intel Pentium III.

2) Has a FSB of 100MHz.

Hmmm,............

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_III_microprocessors#.22Coppermine.22_.28180_nm.29

Scroll down.

Pentium III 1100.

Maximum frequency rate ('Speed') is 1.1GHz (1100MHz)
Front Side Bus = 100MHz
Uses a Socket 370 processor socket.
Part Number = RB80526PY005256
sSpec Number = SL5QW

http://www.cpu-world.com/CPUs/Pentium-III/TYPE-Pentium%20III%20%28Coppermine%29.html

http://www.cpu-world.com/CPUs/Pentium-III/Intel-Pentium%20III%201100%20-%20RB80526PY005256%20%28BX80526F1100256%29.html

In the top header -
Specifications / Pictures (1) / CPU ID (1) / Comments (1),
click on Pictures (1)

You can click on the photo to enlarge.
256MegaByte of L2 cache. (256MB)

A comparable Celeron would have 128MB of L2 cache.

http://www.impactcomputers.com/sl5qw.html

[ Don't forget to follow Anti-Static Precautions.
Clean the bottom of the Heatsink THOROUGHLY, and the top of the Processor if it needs it. (I always do anyway)

PROPERLY apply fresh, new Thermal Paste.

Comp not reading montor


It sounds like the on board video has failed. I would try installing a video card on the motherboard. Then in the bios at start up, disable the on board video, so it will use the video card instead.

I hope this helps and thanks for using FixYa,

DESKTOP COMPUTER TURN ON PROBLEM


In this case it is normally a voltage regulator near the cpu that is shorted and will need to be replaced.
Remove everything from the board, except the heat sink fan and plug in the big power connector, do not connect the 4 pin connector. Turn the power on as you were before.
Using a multimeter, check the voltages on those regulators. You should find them running in pairs normally, but make sure to check all of them and try to pick the odd one out.
Put your black lead to ground, and use some electrical tape to cover all of the red leads probe except for 2mm at the tip to help prevent shorting out anything else while you are there.

Motherboard


Hi, this is an indication of a power surge possibly from a near by lighting strike. Always use a surge protection board. The best solution for another motherboard is to Replace it with a generic brand, if you have any doubt about the size format of the board then buy a mini ATX board and you will find this will fit any case, you do not need to buy the exact same motherboard as the orriginal one. Just make sure your Ram and CPU are the same type as needed on the new board. ie:- socket 775 CPU and DDR RAM or whatever your current board uses.

MY MONTOR HAS POWER AND IS NOT WORKING.


Hi, dont loose faith. If you look on your mother board along the edge closest to the front of the case you will see a series of pins, usualy about 10 pins. Printed on the board will be the names of the plugs that match. The wires from the front of the case have corresponding names. The power and reset switch will work no matter witch way around you put them. The HDD led and the pwr led will only work one way so if these lights dont work, just reverce the plugs. If desperate you can bridge two pins together at a time until you get the on/off switch. Note you cant hurt anything unless you use a hammer. Regards mistyman

HP pavilion laptop shuts down abruptly


It sounds like something is overheating to me. Also, it could be a bad motherboard. Try putting your laptop on a hard surface. I carnt stress this enough. Also, you can try cleaning out the laptops cooling vents with some compressed air (you can get it at pcworld). At the end of the day and it still wont work, send it in for repair. Good luck
