Laptop only charges to 90%

[IanY1]

My battery charge indicator in the SysTray only goes to 90%. My laptop is 18m old. Is this likely to be a battery problem & is so does it matterr ? need replacement. HP Hardware diagnostics say the battery is OK. Or else can I recalibrate it

90% might be the best your "over a year old" battery can manage.

This is likely just "normal wear and tear" (nothing about which you need be concerned).

You can leave it "as is"

OR

Yes, if you like, you can try calibrating the battery.

If the calibration does not work

OR

If the 90% charge capacity is "bugging your trip"

You have the option (if you want to do so) of replacing the battery.

Battery having trouble?

• If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down. Short Version:  An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.
• The battery might be OK and just need calibration (balance / set).

The steps to check / calibrate / replace the battery are included in this document:
