Yes, of course, spend money to buy peace. And D630 has a graphics card defect, which may be broken after the warranty period, so the repair cost is not small. You can go to Dell's technical support forum to see when your warranty period ends, and renew it as soon as it ends.
-
Nothing necessary. It has been three years of on-site service and one year of comprehensive protection. As long as you take care of it, you don't need to add money to buy comprehensive protection if there are no accidents. After all, there are three years of door-to-door service for the main accessories, which is enough.
-
It's necessary! Don't put your trust too much in Dell! As the saying goes, problems are everywhere!
-
The performance of the D630 is good, and if you want to prevent situations like splashing water into the keyboard and accidentally dropping, you can choose this "protection fee".
In fact, this is like insurance, spending money to buy safety
I bought a 640M Dell NB last year, and I bought it for one year of protection, but I accidentally spilled tea into the keyboard a month before it expired, causing the machine keyboard to fail. I gave it to Dell, although it took a longer time before and after, and it took more than a week (a more complicated procedure halfway, although Dell's after-sales service seemed simple), Dell sent someone to replace the keyboard directly. If you choose to change the keyboard yourself, the cost is not small.
-
It's too necessary, but it's quite cheap for you to renew the warranty, because once the warranty is over, your maintenance cost will be far greater than 400 yuan, and you know the quality of Dell, which is not very good.
In short, you have 3 years of full coverage and peace of mind
-
There's no need, unless you buy it when you first buy it, there's no need to buy it again in the future, and the D630 notebook has been officially discontinued.
-
If someone dares to buy it, you can ask, in addition, I asked yesterday that now the price of the extended warranty seems to have increased, and 380 is estimated to be unavailable.
-
You are a nostalgic person, always immersed in your own living space, maybe you broke up because of some unpleasant things, maybe you lost to know how to cherish, but you should grasp everything now, things have passed for three years, do you think you still have a few three years to reminisce, when you are old, and then look back on the past, do you think it is ridiculous.
-
Is there a local area network? It may be limited by others.
-
It's up to you, just like buying insurance, if you think it's worth it, you can buy it, and if it's not worth it, don't buy it, which is a kind of risky investment.
Another point is that the warranty of the notebook itself is two years, and if it is not used frequently, there is no need to extend the warranty.
-
Hello, you can go to our Dell technical forum to check the information, the content here is very comprehensive.
-
If you have a problem with your computer now, you can upgrade your repair service to door-to-door service, ** is also about 500, if you have passed the time of repair service, 2 years is 1500, as soon as possible.
-
Not necessarily.
Please note that the warranty period for laptops is on a part-by-part basis. The whole machine is indeed 1 year, but the screen, motherboard, CPU, hard disk, memory, these more expensive things actually have a 2-year or even 3-year warranty period.
In other words, the laptop manufacturer guarantees that your computer will be able to work normally for 3 years. As for the one-year warranty, it is nothing more than the small parts of the camera, touchpad, keyboard charger, etc., which are cheap, the failure rate is not high, and the third is that you can easily find a replacement, so don't worry too much.
Do you think that your computer will be obsolete in 3 years? Why spend such unjust money?
-
The third floor is too expensive to renew the insurance, and it can generally be used for three years, and it should be replaced when the time comes.
