HP IQ816 - Flash then powers down

HP Recommended
HP iq816 Touchscreen
Microsoft Windows Vista (64-bit)

I have a HP IQ816 Touchscreen.

When I plug the power in and turn it on, there is a visible flash from underneath the unit at the bottom left side of the screen (as you look at it from the front).

It starts and runs for a while without any problem.

Then occaisionally, whether you are using it or not - the visible flash happens and the unit just powers off immediately (not a shutdown type power off).

I can then power it on immediately but the BIOS has cleared all it's settings (time / date etc) and these need putting back in.

It then runs for a while and then does the same thing intermittently..... It can be five minutes after it has started or it can be three or four days but it always does it - flash, no power, machine off.

I have just replaced the Inverter board as I found this as a possible cause on the HP forums but the problem still persists.

Can someone point me in the direction of the actual cause of this problem?

Best regards

Steve

 Hi Steve,

 

Apologies for the inconvinience caused.

Is there a pattern in which the light flashes before shutdown? (example -flashes three times, once every second, followed by a two second pause

Please provide us the LED activity pattern, we will be able to assist you further.

 

Thank you,

Sindu

Hi Sindu and thanks for the response.

This isn't an LED type flashing light, this is a very bright flash coming from inside the unit at the bottom. I would suspect that it is an electrical flash from a short or a component fault.

There is no pattern, there is just one quick flash and then no power to the unit at all.

The machine doesn't power down slowly, the power is cut off immediately as the flash occurs.

Best regards

Steve

Hi Steve,

 

If you see an electrical flash and you feel it is an electric failute on the board, I recommend you to unplug the system from power and do not perform any troubleshooting with it. 

Please call up HP Customer Support, they will help you further with getting the unit serviced as per the warranty options.

 

Best Regards and Good Luck!

Hi Sindu.

This is an old computer which was out of warranty many moons ago 🙂

I just want to know which piece of the internal puzzle is the most likely cause of the problem. I replaced the inverter board and the Blu Ray drive. I'm sure I can replace any other parts that may be past their sell by date - I just need to know which one/s they are.

Best regards

Steve

Hi Steve,

 

Looks more like a system board issue, but I would suggest to take it to an HP authorized service provider.

 

Regards.

I know it's a system board issue...

My question is - can you give me an idea which one it is likely to be?

Best regards

Steve
