Everyone, help all, help all

It seems that it is difficult to buy notebook accessories in the market, and only special maintenance points can order directly from the manufacturer. Consider sending it directly to the second-hand market, dismantling it to sell, maybe there can be a few thousand yuan, and then post some money and buy a new one.

I estimate that if you change the motherboard and graphics card now, it will cost 2700, and now the notebook of about 4000 is already very powerful. Then your old computer only needs to be sold for 1,000 yuan, and you can buy a new one with a little money. Personally, I feel that it is still a good deal.

Lenovo IBM's machine personally feels good, and Acer's is also more cost-effective.

Main board ASUS K50id

Graphics: NVIDIA GeForce GT 320M ( 1024 MB ASUS )

It doesn't seem very convenient for the notebook to change the board by itself. If it takes too long, the board interface may not be compatible with the memory, CPU, etc. It's better to find customer service to repair it.

Motherboards and graphics cards are very expensive, it is recommended that you buy a computer again, don't buy ASUS, ASUS's workmanship is not good, you can buy thinkpad

I think it's better to find the manufacturer's after-sales service to recommend you the hardware that matches your model, and then let people help you refer to it. It's really hard to repair a broken notebook, especially after the warranty period, and the accessories are very expensive.

Find a place to sell your computer and return it to the factory for replacement parts·· After the warranty, the money has to be paid by yourself.

If it's too expensive, change it over.

It's best to use the original notebook If it's very expensive, replace it Anyway, how long have you used it, and the warranty can be sent to the after-sales service.

Classmate, ** can't see clearly, you can take a new picture, I'll wait for you.

What did you do in math class?

a---m---c---n---b

1)ac=6cm,bc=4cm

The dots are the midpoint, respectively.

So mc = 6 2 = 3cm

cn=4/2=2cm

mn=3+2=5cm

2) Set ac=x

mc=x/2,cn=(a-x)/2

mn=x/2+(a-x)/2=a/2

The length of MN is always half that of AB.

It's so simple, the midpoint is halfway.
