The sales person said it was probably best to get a replacement cord from Dell. But, being short of time, I bought the non-Dell brand AC adapter from Staples, and have been using it since. It seemed to work fine — battery was always at “100 percent and charging,” and when I did unplug it, I seemed to get the normal one to two hours of use.But now when I check status on battery icon, it reads “NO BATTERY DETECTED.” And if the AC adapter is unplugged, the orange “low battery” light immediately comes on. Do you think the non-Dell dell latitude d620 batterydell inspiron e1505 battery AC unit might be the culprit?

A: I’m not at all surprised that the battery on a 4-year-old laptop has gone south. As for whether it reached its end any sooner because of the AC adapter you were using, that would depend solely on whether it was defective or perhaps was not the correct voltage.
You’re always safer sticking with equipment from the manufacturer. The downside, of course, is that you generally pay a higher price.
Personally, I’d make that decision after seeing the price differential.
Q: It seems that after one of my drivers was updated my Dell latitude e6400 battery mouse — which I had no problems with before — went south. Is this possible or did the mouse just die? It still works but is very slow in scanning e-mails and such. Very frustrating. Or was this drivers thing just a coincidence?
— R.J. Long, Auburn
A: It’s entirely possible for drivers to conflict with each other. You could try restoring Windows to its configuration before installing that driver and see if the mouse problem goes away. To do so, go to the Control Panel and launch the System utility. Next, click on the System Protection tab and then click the System Restore tab.
If that solves the problem, you can choose between reinstalling the driver and having to try another mouse. If it doesn’t solve the problem, you’ll know your mouse is dying all by itself.
Q: I went into my Yahoo e-mail account the other day and all of these returned hp pavilion dv6 battery Hp elitebook 8530w battery undeliverable messages were in my inbox. It looks like someone got into my Yahoo account. I changed my password for Yahoo. Should I change all my other passwords for every account I have? (I think I have more than 1 million passwords at this point in my life.) How did this happen? Does anti-virus protect from this problem? I am a Mac user so I don’t have an anti-virus program.
— Margaret Wallace
A: Anti-virus software may or may not help protect you from this problem. One way spammers get e-mail addresses — as well as take control of computers for sending spam — is through viruses.
I strongly recommend that any computer connected to the Internet — including Macs — be protected Hp pavilion dv3500 battery by anti-virus and firewall solutions. Apple also recommends this.
It’s also a good idea to use “strong” passwords — passwords of at least eight characters, with letters and numbers — and to change them frequently.
