Hello and welcome to Bleepingcomputer.

I see where your thread was getting pushed along the forum pages without any input and before it goes further into the void I wish to jump in and save it by answering your question with a question.

If you are experiencing errors related to your CPU, have to tried the easiest remedy of blowing out the processor heat sink with compressed air?

You obviously have a hardware error or failure, this may have been caused by an over-heated component that has reached the point of complete failure.

A remedy may be disassembling the laptop and gaining full access to the processor, removing it from the ZIF slot, checking it for signs extreme heat exposure.

I do not know how comfortable you are with attempting this because laptops can be a pain to work on.

The ribbon wires inside which connect the various boards together are connected to very fragile ZIF flip lock connectors.

Those flips are very easy to snap off rendering the connector useless and replacement is a complete nightmare because the boards use micro surface mount technology.

The solder pins on those connectors are so CLOSE together, it is almost impossible not to get solder bridges joining the connectors together causing dead shorts.

No one said this new method of doing things was the best idea, I personally think surface stinks, but it also saves the consumer money, by having parts that use a lot less minerals than that of the older bulky parts of the old 'tube' and 'solid state' electronics era.

This has also rendered most electronics equipment of today as 'disposable' technology, the cost of repair far out-weighs the price of a 'new' piece of equipment.

A detailed service manual is a must have if you wish to fix this unit yourself.
Are you willing to do this repair?

Bruce.
