Dell’s built-in diagnostics (ePSA) are designed to identify hardware-level problems before Windows even loads. If you see:
- ePSA error code: 2000-0135
- Message: “Battery – Not a Dell battery. The computer cannot charge this battery.”
…this is Dell telling you the system cannot properly identify/authenticate the installed battery, so charging is blocked.

1) First: confirm you have the “battery identity” version of 2000-0135
Dell’s own reference table shows that 2000-0135 can appear with different text. One entry is the battery identity message (“Not a Dell battery”), and another entry uses the same code for a charger-related “unexpected charge condition.”
So always diagnose by the exact wording shown on your screen, not just the number.
2) What 2000-0135 (Not a Dell battery) actually means
This code typically indicates a failure in the battery identification/communication path. Dell’s troubleshooting notes explain it as an error that may involve the battery or the main system board, and that charging is not allowed when the battery cannot be identified.
In plain English: the laptop cannot reliably read the battery’s data (ID/health/communication), so it refuses to charge.
3) The most common causes
- Incompatible battery type (the battery “fits” but isn’t the correct model family for your Dell)
- Battery controller/ID circuit failure inside the pack
- Loose battery connector (especially after replacement, repair, or a drop)
- System-board charging/communication fault (less common, but possible)
4) What to do next (Dell-style troubleshooting order)
Step A — Re-run diagnostics with the charger attached (important)
Dell specifically recommends repeating the diagnostics with the charger attached as directed by the test. This helps rule out “test conditions” and confirms the result is repeatable.
Step B — Update BIOS to the latest version for your exact model
Because battery identification and charging logic are firmware-controlled, BIOS updates can sometimes resolve detection/authentication issues. After updating, run ePSA again.
Step C — Check whether the battery is correctly matched and properly seated
- If the battery is removable: power off, remove it, inspect contacts, reinstall firmly.
- If the battery is internal: follow Dell’s service manual for your model, or have a technician reseat the battery cable (this is a very common real-world fix after battery replacements).
Step D — If it still fails, submit the error online (service-tag + validation code)
Dell provides an ePSA online submission process where you enter:
- Error code (2000-0135)
- Validation code
- Service Tag
This is the cleanest next step when you’ve updated BIOS and the error keeps returning.
5) Should you replace the battery?
Replacing the battery is usually the right move when:
- The error returns after BIOS update + re-test with charger attached
- The laptop won’t charge the battery at all
- You recently installed a replacement battery and the code appeared immediately (high chance of mismatch or a defective pack)
- The battery shows other clear symptoms: very short runtime, sudden shutdowns, swelling, or rapid percentage drops
Before you replace, make sure you’re choosing a battery that matches your exact Dell model (and ideally your original battery type/part family). A “close-looking” battery from a similar series can still trigger identification errors.
6) How to avoid 2000-0135 in the future
- Match by exact Dell model (and if available, the old battery type/part number).
- Confirm voltage and connector match the original battery.
- After installation, run ePSA once and check BIOS battery info to confirm proper detection.
FAQ
Can I keep using the laptop if it shows 2000-0135?
Often yes—especially on AC power—but Dell is warning that charging is blocked. The practical risk is sudden shutdowns if you unplug, plus ongoing battery/charging instability.
Why does Dell block charging for “not identifiable” batteries?
The system uses battery identification and health data to manage charging safely. If that data can’t be trusted, charging may be disabled.
What information should I save before contacting support?
Save the error code, the validation code, and your Service Tag. Those are exactly what Dell’s online submission process requests.
