last time I published a series of models by HP existing problems; present hp notebook BIOS problems caused by a common problem has been demonstrated phenomenon! performance issues are as follows: 9 J $ U2 T # M! G: K%? First: the official launch of the BIOS version F.55 of the BIOS are the adapter detects not, can not boot with the adapter, single-use batteries can not, at the same time to be inserted into the boot. ; E2 F + R0 R1 R5 Z1} i1 "| * Z 2 a second: the official launch of the highest version of F.67 BIOS, such as installation of XP, then install the network card or sound card can go up very, or not detected, but some models can be. Third: Some models black, the first graphics card that is the problem of comrades attention, and general machinery produced in the BIOS versions of the BIOS to F.55 This version is also the most vulnerable, after the first brush, the BIOS will not rush to do graphics. Fourth: brush before please make a backup BIOS, the BIOS brush some black friends, and here a failure, no BIOS machine brush back. !] & T! S: L1 O [ solution as follows: First, the HP website (http://www.hp.com.cn ) Download the BIOS file to the corresponding model , use WinRAR to extract, which have similar 30F7F24U.FD and 30F7F24D.FD two files, where D represents an independent graphics card models, u on behalf of integrated graphics models. to find the corresponding BIOS file, u disk with a small-capacity ( best no more than 1GB), format it to FAT or FAT32 format (but do not create the boot disk), then copy the files into the corresponding BIOS Copy the complete need to rename the BIOS file, leaving only the front of the 30F7 characters FD and the suffix changed to BIN.will u disk into the machine and remove the laptop battery while holding down two buttons WIN + B to boot attention to boot to hold down two buttons, then release the power. when Hewlett-Packard Blind notebook refresh operation will enter the BIOS, first blew out, and then the beep sound that you locate a BIOS file into the program after their calls to refresh the basic stop, refresh will shut down automatically after successfully again start, everything will be back to normal a. S
