Intermittent black screen

[GJL03]

Trust me, I'm a novice... with two presumably connected issues:

1. Periodic blackscreening when in normal use. Doesn't appear to be a specific action/cause.

2. Power button stuck in stand by mode (flashing) when powered back up and will not boot.

The only solution I have found is to close the screen down/open it up again (sometimes several times) notebook will eventually boot up normally. Under moderate use the laptop will work fine for days/weeks until same issue.

Took it to a repair shop and they said it was needing a new motherboard. I was thinking it may be power/battery related? Any help welcome, a solid,  relatively new laptop I'd like to save is possible.

Sad to say, the repair shop is probably right. Sounds like some component on the motherboard is marginal, working sometimes and not others. Just a matter of time before it stops altogether.

The value line of HP laptops aren't designed to last much beyond the warranty period. Any of the tiny components on the motherboard that fail render the device unbootable, and repair costs can exceed half the cost of an upgrade.

It is also possible the thermal cycling could cause the solder joints to become marginally connected. The only practical solution is a motherboard replacement.

Even if you replace the motherboard, your replacement will suffer from the same subpar design, so better to put the money towards a new, higher quality laptop or a newer design budget laptop.

Thats very helpful on several levels, thank you for the information. Have to say I was expecting more from this device which was in excess of £500 with upgraded processor chip. Low to moderate use only.
