First check whether the power cord and socket are normal, try to press the power button to force the shutdown and restart. If it still fails to boot, it may be the power module or motherboard fault, it is recommended to dial 020-39029800 to arrange on-site diagnosis.

Blue screen is usually caused by drive conflicts, memory failures, or system file corruption. Try to uninstall recently installed software/drivers after safe mode boot. Repeated blue screen recommended to check memory and hard drive health.

Stunning is caused by aging mechanical hard drive, insufficient memory, too many boot items or poor cooling. The most effective speed increase is to upgrade the solid state drive (SSD) and expand the memory. With system optimization, the old computer can speed up 3-5 times. We provide diagnosis (RMB 50–150), giving the most cost-effective upgrade plan.

The first time to power off, unplug the power and battery, inverted water control, do not try to turn on or charge to verify "still cannot use". Then dry the surface moisture with a dry towel, as soon as possible repair. The sooner the water treatment, the higher the repair rate of the motherboard, delay will lead to increased circuit corrosion.

First confirm if it is a hardware failure or a system/network issue. Hardware failures (power/hard drive/memory) need to be replaced in the field; system issues can be attempted by remote restart or restore snapshots. Our engineers provide 7×24 remote + onsite support.

It is very necessary. The server is running under high load for a long time, and fan dust accumulation, hard drive aging, array degradation, and missing system patches are all hidden dangers. It is recommended to conduct a quarterly inspection (hardware health/array status/log analysis/cooling) to prevent sudden downtimes. The probability is reduced by more than 80%. We provide flexible maintenance contracts.

Most RAID levels (0/1/5/6/10) are recoverable after a crash. The key is not to write to the failed disk. Our cleanroom lab supports all types of RAID reorganizations and data recoverys.

Yes. Delete operations simply mark the space as available and the data itself is still there. As long as no new data is written over, it can be retrieved by professional recovery software or hardware means. The success rate is inversely proportional to the number of operations after deletion.

Data recovery is charged according to fault type and difficulty: logical faults (error deletion/error formatting/partition loss) start at several hundred RMB; physical faults (head damage/motor seizure/bad sectors) require cleanroom-cleanroom platter recovery, and the cost is relatively high.

Yes. If the phone cannot be turned on, flooded, deleted by mistake, etc., photos, contacts, SMS and chat history of mainstream social software can be extracted through chip-level reading or special tools. iPhone and Android are supported. Device ownership needs to be verified before recovery, and a confidentiality agreement is signed throughout the process.

Guaranteed. We strictly abide by data confidentiality specifications: sign a confidentiality agreement before any work starts, and all operations involving data are carried out in a dedicated isolated environment. After recovery, the source media will be handled according to your requirements. Zero data leakage accidents in 15 years, which is also the reason why a large number of enterprise customers choose us for a long time.

Category V or Category VI cables are recommended, following TIA/EIA-568 standards. Horizontal cabling should not exceed 90 meters, and patch frame-to-switch jumpers should not exceed 10 meters. All cables should be labeled and numbered and test reports should be retained.

Make sure the router is centered and unobstructed, and the channel is congested (available with Wi-Fi analysis tools). Mesh networking or AC+AP is recommended for large units. We provide free on-site wireless survey services.

Common causes include: insufficient router performance, channel interference, poor cable quality, too many terminals, broadcast storm. We will do site survey to locate the root cause, and then targeted solutions-may need to replace enterprise-level routing/AP, re-planning channels, replacement of Class 6 cables or VLAN division. Most cases can be cured once construction.

It is very necessary. Monitoring is not only anti-theft, but also a management tool (remote view/dispute forensics/safe production). Selection suggestions: shops/offices can use 4-8 POE network cameras +NVR, factories/warehouses increase points according to the area and consider night vision and waterproof. We provide free on-site survey and scheme design.

Billing has two parts: data-centre resource fees (rack space, bandwidth, power, IP addresses) are charged and invoiced directly by the licensed IDC provider, while our technical service fee covers racking, deployment, system configuration and day-to-day operations. We assess your needs first and then quote, with monthly or annual payment options.

For enterprises with less than 5 racks and limited power/network requirements, renting space in a licensed IDC facility is usually more cost-effective, eliminating one-time investment and continuous operation and maintenance labor such as equipment room decoration, UPS, precision air conditioning, fire protection, etc. Self-built equipment rooms are suitable for enterprises with compliance requirements or large-scale deployment. We can do input-output comparison analysis for you.

Brand PC build is convenient after sale, but the premium is high, and the upgrade space is small. Self-assembled PC build is cost-effective and optional, but it requires professional knowledge. We provide on-demand PC build service, taking into account cost performance and after-sales protection.

SSD is recommended for system disk and common software (more than 10 times faster); HDD is available for large-capacity storage/backup (cost-effective). SSD+HDD hybrid solution or all-flash array is recommended for enterprise scenarios.

A look at the channel (choose a physical store and regular invoice merchants), second look at the price (obviously lower than the market price of most of the greasy), third look at the packaging and serial number (can be verified by the official website), four to warranty certificate. All our accessories are channel direct supply of brand-new genuine, support inspection, false one compensate three.

Guangzhou (Tianhe/Haizhu/Yuexiu/Liwan/Baiyun/Panyu/Huangpu/Nansha/Huadu/Zengcheng/Conghua) can be on-site, some remote areas may charge a small amount of transportation fees. Emergency failure response within 2 hours.

Hardware repair/replacement warranty 90 days, system reinstallation warranty 30 days, network engineering warranty 1 year, IDC colocation is governed by the provider's contract SLA. Free repair of the same fault within the warranty period.

Yes. We are a registered company. All maintenance, engineering and sales services can be invoiced (VAT invoice). Corporate customers support corporate transfers and monthly settlements. Individual customers can also ask for invoices as warranty certificates.
