Yesterday morning, as usual, came to the station, open the laptop, the computer found nothing happens, it can not be switched.
I encountered this problem thinking process is as follows:
1, Baidu
Phone Baidu has about similar problems, largely determine the possible causes, prepared according to the tutorial detection. But found no tools, tool start looking around, and finally in the hardware store to buy a set of 10 yuan. It began to dismantle the rear cover, remove the battery, the amount, the battery will not split. Again Baidu has about how to remove the battery, to no avail, to abandon this plan.
2, near the repair shop
Search nearby repair shop on Baidu map, bring the computer went. The first store has not opened the door, shop for second place, but provide on-site maintenance services. So I called and was told to wait until the afternoon free. But I did not want to, etc., in the online search a little home repair phone, the points go, and soon received a phone call, he asked about the problem, arrange over.
Soon came a maintenance staff, try a few times not, say, a bad motherboard, the motherboard needs to be replaced, offer more than a thousand, the computer needs to take. I said that I think about it, when ready to go, he said to give on-site service costs 50 yuan. Well, I also very uncomfortable, consult a moment, she gave him 30 yuan tolls run. This plan failed.
3, after-sales application
Baidu's online computer sales customer service, turned engineer, as he was asked to do two tests. (1) disconnect the power, press the power button for 30 seconds, the release of static electricity, and then plugged in the normal start; (2) Disconnect the power while holding ctrl + esc, and then plugged in the normal start. Both tests failed, engineers speculated that the motherboard may be a problem, ask the address and contact details, to arrange the next day arrangements for staff to deal with.
This morning, to an engineer, examined the motherboard, hard drive, detect possible problem is that SSDs unstable, but the self-test computer, boot no reaction; bad wiring board, can not be switched. After removing the hard drive to re-accord, successfully detected; motherboard rubbed with an eraser to remove a few joints, put back, the computer starts successfully.
The solution presented followed by: (1) the computer starts successfully, you can normally use, does not rule out the possibility of failure occur again; (2) recording the issue, motherboard and hard drive may be defective; (3) advance backup SSD data, if the next fails, arrange to come directly replace the motherboard and solid state drives. Say something, my computer in the maintenance period, all free of charge. So far, the problem is solved, thanks, not before.
Summary: My skill level in general, but more kindness, hope to help yourself or someone else to solve the "small problem", when they can not find time to be resolved, guilt and self-blame would doubt his ability. Also, the problems encountered will be very upset and would like to get rid of the first time.
(1) "small problem" may not be small, deal with problems encountered correctly, you are best to normalization process.
(2) problems, upset will affect their judgment, the correct approach is to assess the damage and solve the problem.
Add that: My computer is a Dell notebook G7, before the computer is not particularly satisfied with this, because solid-state problem, reinstall the computer system twice (own equipment), bought more than a year, is a three-phase maintenance year.
