HP Notebook PCs - 601 or 60X Error Displays on a Black Screen

This document pertains to HP notebook computers with the HP Unified Extensible Firmware Interface (UEFI) beginning in late 2008.

On startup, the computer performs a battery check by examining the remaining capacity of the primary battery as well as the capacity of any secondary battery that may be installed.

If the system detects that the storage capacity of the battery is very low, it displays one of the following alerts.

Identifying the newer HP Battery Alert error (601)

Identifying the older HP Battery Alert error (601)

The message displays for 15 seconds as the normal startup process continues.

Differences between battery messages (601–605, 607–608)

601: If Primary (internal) Battery (601) appears in the alert message, it means the measured storage capacity of the primary (internal) battery is less than 25% of the original storage capacity. The number “601” denotes the associated error code that is recorded in the system log. This might be caused by environment factors like low ambient operating temperature, or due to the aging of battery pack. Operating your system in a warmer location for a while might resolve the condition.
602: If Secondary (external) Battery (602) appears in the alert message, it means the measured storage capacity of the secondary (external) battery is less than 25% of the original storage capacity. The number “602” denotes the associated error code that is recorded in the system log.
603: Battery not present – Primary battery is not detected by the detected by the test.
604: Battery Charge Level Error – The test cannot determine the correct charge level of the primary battery.
605: AC Adapter Error – The test indicates that the battery is not receiving a charge.
605: Battery Counterfeit Check Error (605) – A non-HP battery was detected. If you purchased the battery from a reseller, contact HP.
607: Primary (internal) Battery is Weak with Low temperature.
608: Secondary (internal) Battery is Weak with Low temperature.

Resolving the Battery Alert message

Step 1: Update the BIOS to the latest version

Download a BIOS update from the HP website. Go to the HP Customer Support - Software and Driver Downloads page.
Navigate to the product page for your computer.
Select BIOS from the list that displays, and then review any available BIOS updates.

caution:
Confirm that the BIOS update is more recent then the one installed and that it applies to your computer. Installing the wrong BIOS could cause your computer to stop working. For more information about updating the BIOS, see Updating the BIOS (Basic Input Output System).
- If you do not see a BIOS update listed for your computer, no update is currently available.
- If you find a BIOS update, click Download, and then click Save.
Browse to the folder or desktop where you saved the downloaded BIOS update file, and then double-click the file name (example: sp12345) to start the installation.
Wait for the computer to install the update. The computer might beep, turn off and on the display or cooling fans, or display a blinking power light. This is normal.

caution:
Do not turn off or restart the computer until the update process completes.
Click Yes on the User Account Control screen.
In the InstallShield Wizard window, click Next.
Select I accept the terms in the license agreement, and then click Next.
On the HP BIOS Update and Recovery window, click Next.

note:
Windows that display during the update process might vary depending on your computer.
Select Update, and then click Next to prepare the update.
Click Restart Now to install the update.
On the HP BIOS Update screen, click Apply Update Now, or wait for the update to start automatically.
Wait while the BIOS update installs. The computer displays the installation progress.
When prompted, click Continue Startup, or wait for the computer to restart automatically. It might take a few minutes for the computer to restart.

note:
If the update fails, a failure screen displays with additional information. The system might run a BIOS recovery after restarting. Do not attempt to turn off the computer if this happens.

note:
If a '251' or CMOS Checksum error displays after the update, go to Error: CMOS Checksum Bad to resolve the issue.
When the lock screen displays, sign in to your computer.

Step 2: Test the battery using HP Hardware Diagnostics

To resolve a Battery Alert message, you should perform the Battery Test in the System Diagnostics (F2) environment, and then calibrate the battery for best performance.

To access the HP System Diagnostics Battery Test, turn on the computer and immediately press the esc key to display the Startup Menu. Press the System Diagnostics F2 key, and then select the Battery Test option.

For instructions on testing the condition of your battery, see Testing and Calibrating the Battery (Windows).
