Question: How do I install it on a CQ-50 and do I need to mess with the Bios after installation?
Document: Excellent product! This choose was cost efficient and was easy to install. I sense more likes for this CMOS Battery type.
So far so good. No problems thus far. Super easy to install once I found which compartment actually held the battery.
The price was right, and an easy install. I'll be using more products from you to do customer repair work.
It works been using it for about 13 months on my Q Presario CQ50 installation was easy plug n play and no problems.
It came pretty quickly and in protective bubble packaging. Was exactly as described, and was pretty close to being identical to the original battery that I was replacing. No complaints here! Thanks, much appreciated!
I plugged in the battery and it does not work. Went back to make sure it was plugged in correctly. I still get the same error on the computer. Garbage. Can't get a hold of the company.
I like how fast it was sent to me and then to find two of them (CMOS Battery).Very good deal.Yes I will be telling all this to all of my friends and my friends, friends.Thank you.Corby T Clegg
The battery worked but the wires that ran into the connector slid out while I was installing the battery. The wires were not soldered to the connector at all, I was able to slide them back in but this battery is about as cheap as it gets....guess you get what you pay for.
Battery looked to be a direct replacement for the CMOS battery in my Compaq laptop. I found a video on Youtube which showed how to replace it and pressed F12 upon start up of computer and the computer booted correctly.
Hi, I was a little disappointed that I received the wrong battery, initially, (not sure if it was my error or the company sending the battery) but it was remedied, immediately, beyond all my expectations. I returned the incorrect item and within 24-48 hours I installed the correct one in my computer. Thank-You, Thanks-You and Thanks-You!
