Fortunately, such a solution is found rarely and only on the old boards.On very old boards instead of the battery uses a special rechargeable battery.

If you are sure that you will be able to choose a new battery, bring the old shop. Note that some motherboards allow the installation of elements of two types: CR2025 and CR2032. The second is preferable: it usually costs as much and lasts longer. Do not look for expensive batteries, because in life they do not differ from cheapest of the same size.In computers Hewlett Packard can be used non-standard batteries. With the high price of new batteries in this case will have to accept.
To install a new element, position it positive output to itself and place under the focus, located in the holder in front of the striker. Click on the battery, and it will be under the retainer.
If you removed the PSU, put him in his place. Connect to computer the power cord or turn on power supply a switch. Close the computer case, open it, and then start to quickly press the keyboard key "F2" or "Delete" (depending on motherboard model), until the entrance in the CMOS Setup. Re-set the time and date, then save the settings. Start computer use.
