Before You Give Your Laptop for Repair — 10-Point Checklist Every Delhi Office and Home User Should Follow
Most people hand over a laptop for repair the same way they hand over a car for servicing — trusting that the professionals will do their job and return everything as it was. With cars, that is mostly fine. With laptops, it is a risk you should think about before you walk in the door.
A laptop going in for repair may need to be opened, reset, reimaged, or in some cases have its storage accessed as part of diagnosis. None of these processes are inherently problematic with a reputable repair centre — CNC has serviced thousands of laptops since 1996 and the data question is never a grey area for us. But regardless of which service centre you use, you should take these steps first. They protect your data, your privacy, and give the technician cleaner conditions to work in.

The 10-Point Laptop Repair Checklist
1. Back Up Your Data — Before Anything Else
This is not optional and it is not “do it if you have time.” Do it first, before the laptop goes anywhere.
Many repairs — screen replacements, motherboard work, severe malware removal, OS reinstallation — can be completed without touching your data at all. But hardware failures can be unpredictable, and some repair scenarios (like a failed boot drive) require accessing or moving data as part of the fix. If the drive itself is the problem, backup may no longer be possible after the failure deepens.
How to back up before a repair:
- External hard drive or USB drive — manually copy Documents, Desktop, Downloads, and any other folders where you keep active work. This is the fastest option if your laptop still boots.
- OneDrive / Google Drive / iCloud — if your files are synced to a cloud service, verify that sync is complete (check the sync status icon in the taskbar). Do not assume it is up to date — check the actual last sync timestamp.
- Windows Backup — Control Panel → Backup and Restore → Set up backup. This creates a full image or file backup to an external drive.
If the laptop will not start and you have not backed up, call CNC before bringing it in. Our team can often extract your data first before proceeding with repair. See our data recovery service for cases where the drive itself is the issue.
2. Note Down Which Files and Folders Are Most Important
After a backup, write down (or photograph) the folder structure of your critical files. If something goes wrong during repair and data needs to be restored, you will know exactly what to look for and can verify the restore is complete. A vague “I had some documents in there” makes post-repair verification very difficult.
3. Sign Out of All Accounts
Before handing over the laptop, sign out of:
- Your Microsoft account or Apple ID (linked to Windows activation or macOS on MacBooks)
- Google Chrome, Firefox, or Edge — sync sign-in, not just the browser history
- Email clients (Outlook, Thunderbird, Windows Mail)
- Banking, financial, or business applications
- Any business software — Tally, CRM, ERP — that stores credentials locally
This is not about distrust — it is about hygiene. A signed-in browser profile accessible on your laptop means your saved passwords and browsing history are one click away. No reputable technician will use them, but removing the temptation and the exposure is the right approach.
4. Write Down Your Passwords Separately — But Do Not Leave Them on the Laptop
Some repairs require booting into the operating system — the technician will need your Windows login password or PIN, or your MacBook login password if the disk is encrypted with FileVault. Give this information at handover in person or on a slip of paper that you take back, not as a sticky note on the laptop lid.
Also note: a legitimate repair centre will ask for your password to boot the machine if needed — they will not ask for your email password, banking password, or any online account credentials. If a technician asks for those, that is a red flag.
5. Remove External Storage and Accessories
Take out any USB drives, SD cards, external hard drives, or peripherals that are plugged into the laptop. These are easy to forget and easy to lose in a workshop. If you have a laptop with a SIM slot (some business models), remove the SIM card.
Also remove any laptop stand, keyboard cover, or skin if they are removable — they may interfere with some repairs and are easier to keep track of at home.
6. Note the Current Condition of the Laptop
Before handing over, check and note:
- Any existing scratches, dents, or broken plastics — so these are not attributed to the repair
- Whether the battery percentage and charging behaviour are normal — this helps the technician if the issue involves power
- Any programmes or applications that are running slowly or behaving oddly — even if the main complaint is different, this context helps diagnosis
A reputable repair centre will also conduct their own condition check at intake and note it on the job sheet. Ask for a copy of the job sheet — it is your proof of condition at time of handover.
7. Ask for a Written Job Card
This is non-negotiable. A job card (also called a service receipt or job sheet) should include:
- Your name and contact number
- The laptop model and serial number
- The problem described in writing — your description, not just “repair”
- The condition of the device at time of intake
- The estimated cost of repair (or a range, if diagnosis is needed first)
- Estimated delivery date or timeline
At CNC, every laptop that comes in gets a numbered job card and the customer gets a copy. This is standard practice at any professional repair centre. If a shop hands back the laptop without having created a job card at intake, that is a sign of disorganised operations.
8. Clarify the Warranty on the Repair
Ask specifically: “If the same problem recurs after repair, what is your warranty policy?” A reputable centre gives a clear answer. CNC provides a 90-day same-issue warranty on all laptop repairs — if the same fault reappears within 90 days of repair, we fix it without charging again.
Unscrupulous repair shops may fix a symptom without fixing the root cause, and a short or no-warranty policy means you will pay again when it comes back. Get the warranty commitment on the job card.
9. Get a Clear Estimate Before Authorising Any Work
For any repair beyond a basic cleaning or software fix, you should receive a diagnosis-first workflow:
- Technician diagnoses the fault
- Quotes the cost of repair including parts
- You approve before any parts are ordered or installed
A repair centre that starts work and then tells you the cost afterwards is not operating in a customer-first way. The diagnosis fee (if any) should be stated upfront — at CNC, diagnostic assessment is free, and repair cost is quoted before work begins.
10. Save the Laptop’s Specifications and Serial Number
Before the laptop leaves your hands, note or photograph:
- The serial number (usually on a sticker on the base, or under Settings → System → About in Windows)
- The model number and RAM/storage configuration
- The Windows licence key if it is a sticker key (not needed for OEM keys tied to motherboard, but useful for retail purchases)
The serial number is your proof of ownership if there is ever a dispute, and it identifies your specific unit in a busy workshop.
A Note on MacBooks Specifically
MacBook users should do two additional steps before any repair:
- Disable Activation Lock — go to System Preferences → Apple ID → Find My Mac → turn off “Find My Mac.” This is required for the technician to reinstall macOS or access the drive. A MacBook with Activation Lock enabled is a paperweight for any technician.
- Back up using Time Machine — if you have an external drive, Time Machine creates a full incremental backup. Restore from this backup is fast and complete. One hour before the repair appointment is enough time to run a final Time Machine backup.
When You Should Not Wait — Bring It In Immediately
If any of these are happening, do not delay repair trying to back up first — call CNC and ask how to safely handle the situation:
- The laptop fell in water or liquid — switch it off immediately and bring it in. Do not attempt to switch it back on.
- The hard drive is making clicking or grinding sounds — this indicates physical damage and continued use risks permanent data loss
- The laptop switches off without warning mid-use — possible battery swelling or heat issue; continued use is a fire risk in some cases
See our guide on 5 checks to do before visiting a repair shop for situations where you are not sure whether the issue needs a service centre visit at all.
Frequently Asked Questions
Will the repair centre be able to see my personal files during the repair?
A technician doing hardware work — replacing a screen, fixing a keyboard, replacing a fan — does not need to access your files. A technician doing software work — removing malware, reinstalling Windows, fixing boot issues — may need to boot the system and could potentially see the desktop and open files. This is why signing out of accounts and backing up sensitive data before handover is the right approach, regardless of which centre you use. At CNC, all technicians work under a code of conduct — client data is not accessed beyond what is necessary for repair.
What if I cannot back up because the laptop will not start?
Call CNC before bringing the laptop in. Our team can often boot the laptop in recovery mode, connect an external drive via USB, and copy your data before proceeding with the repair. In cases where the storage drive itself has failed, we offer a professional data recovery service. Do not attempt to power it on repeatedly — this can worsen the situation if there is a hardware fault.
Should I factory reset my laptop before giving it for repair?
No — not unless the repair specifically requires a clean install and the technician advises it. A factory reset deletes all your data and programmes, and most repairs do not require it. If you factory reset before a hardware repair (screen, keyboard, battery), you have lost all your data for no reason. Back up, sign out of accounts, and let the technician do the minimum necessary for the specific fault.
What is the repair warranty at CNC?
CNC provides a 90-day same-issue warranty on all laptop repairs. If the same specific fault recurs within 90 days of the original repair, CNC fixes it without additional labour charges. Warranty does not cover new faults unrelated to the original repair, physical damage after repair, or water damage on a previously liquid-damaged unit that was only partially repaired.
Is it safe to give a laptop with Tally data or business accounting files for repair?
Tally data files are stored in a specific folder (usually C:\Users\[username]\Tally.ERP9\Data\ or similar). Back this folder up to an external drive before any repair. If the repair requires a Windows reinstall, your Tally data will be wiped along with everything else — but a backup means restoration takes minutes. CNC is a Tally-authorised partner and can also help restore Tally data after a reinstall if needed.
How long do laptop repairs usually take at CNC?
Most common repairs — screen replacement, keyboard, battery, fan, RAM and storage upgrades — are completed same-day or next day. Motherboard-level repairs and data recovery take 2–5 working days depending on parts availability and complexity. CNC will give a specific timeline at the time of diagnosis and will update you if it changes.
