I'm unable to log in on my lap top, when I try it just shows a black circle

Let's perform some troubleshooting steps to fix the issue, ajwplumbing.

Intuit recommends Google Chrome as the default web browser. Other web browsers have similar capabilities but may look different while performing the function.

But if you're still experiencing an issue, there are times your browser is full of frequently accessed page resources that may cause some unusual responses. To isolate this, you can log into your QuickBooks Online (QBO) account in a private window (incognito). Here's how:
 

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox).
• Control + Option + P (Safari).

Once done, check if you're already able to sign in without issues. If so, return to your default browser and clear the cache to speed up the loading process. Usually, the cache becomes overwhelmed with older data which can potentially cause viewing and performance issues. Clearing it will refresh the system, and you'll be able to work with a clean slate. However, if the issue persists, you can use other supported browsers. 

Moreover, QuickBooks also relies on your computer or device's processing power, the amount of available memory (RAM), and the bandwidth of your internet connection. To learn more, you can go through this article for additional information: Why Is My QuickBooks Online Slow?
