Lenovo warranty claims: ThinkPad, IdeaPad and the depot process
How to check Lenovo warranty status, file a claim, use Customer Replaceable Units, and escalate a repair that has stalled.
Lenovo’s consumer warranty is typically one year on IdeaPad and Legion lines, with ThinkPad often carrying longer terms depending on configuration. Business machines are frequently sold with three-year coverage that the buyer does not realise they have.
Check the machine type and serial first
Lenovo identifies machines by a machine type model number and a serial number. Both appear on a label on the underside. In Windows, run wmic bios get serialnumber, or open Lenovo Vantage which displays warranty status directly.
Enter the serial on Lenovo’s warranty lookup page. This tells you your coverage type, whether you have depot or onsite service, and the expiry date.
Lenovo warranty start dates are frequently wrong on machines bought through resellers, because coverage is registered at shipment rather than at sale. Submit your invoice through Lenovo's warranty entitlement update process to correct it. On a three-year warranty this can recover a meaningful amount of coverage.
Customer Replaceable Units
Lenovo uses CRUs more heavily than most manufacturers. Rather than shipping the machine away, Lenovo will send you the part and you install it yourself, with documentation provided.
Common CRUs include keyboards, drives, memory, batteries, and on many ThinkPads the palm rest assembly. This is usually the fastest resolution available and it does not affect your remaining warranty.
If a technician suggests a depot repair for something that is a CRU on your model, ask specifically whether the part can be sent to you instead.
What is covered
Manufacturing defects: display failures without impact damage, keyboard failures, fan and thermal faults, motherboard failures, dead drives, hinge failures not caused by a drop.
Not covered: accidental damage, spills, cosmetic wear, and battery capacity decline within the expected range. Lenovo sells Accidental Damage Protection separately.
Swollen batteries are a safety matter, not just a warranty one. Stop using the machine, do not charge it, and say the word "swollen" when you contact support. It changes how the case is handled.
Filing
Run Lenovo Vantage’s hardware scan first. It produces a result code you can quote, which shortcuts scripted troubleshooting the same way Dell’s and HP’s diagnostics do.
Then open a case through Lenovo’s support site. Record the case number and quote it every time. Depending on coverage you will get a CRU shipment, a depot repair, or an onsite technician.
For depot repairs, photograph the machine on all sides before packing, and back up first. Lenovo’s terms make data your responsibility and depot returns sometimes come back reimaged.
Escalating
Lenovo cases stall in the usual ways: parts on backorder, a machine sitting at depot with no status change, repeated failed repairs on the same fault.
Ask for a case manager rather than continuing with rotating agents. If the same component has failed repair twice, ask explicitly about a unit replacement — repeated failed repairs are the standard grounds across all manufacturers.
Beyond that: written complaint to Lenovo customer relations, then your state attorney general’s consumer protection division, then small claims court.
Keep a dated file of every case number, promise and timeline. It is what makes an escalation credible and it cannot be reconstructed later.
